The FCC Wants You to Know  
This scanner has been tested and found to comply with the limits for a scanning receiver,  
The FCC Wants You To Know  
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable  
protection against harmful interference in a residential installation. This scanner generates,  
uses, and can radiate radio frequency energy and, if not installed and used in accordance  
with the instructions, may cause harmful interference to radio communications.  
However, there is no guarantee that interference will not occur in a particular installation. If  
this scanner does cause harmful interference to radio or television reception, which can be  
determined by turning the scanner on and off, you are encouraged to try to correct the  
interference by one or more of the following measures:  
• Reorient or relocate the receiving antenna  
• Increase the separation between the scanner and the receiver  
This device complies with Part 15 of the FCC Rules. Operation is subject to the following  
two conditions: 1) This device may not cause harmful interference, and 2) this device must  
accept any interference received, including interference that may cause undesired operation.  
Scanning Legally  
Your scanner covers frequencies used by many different groups, including police and fire  
departments, ambulance services, government agencies, private companies, amateur radio  
services, military operations, pager services, and wireline (telephone and telegraph) service  
providers. It is legal to listen to almost every transmission your scanner can receive. However,  
there are some transmissions that you should never intentionally listen to. These include:  
Telephone conversations (cellular, cordless, or other private means of telephone signal  
transmission)  
• Pager transmissions  
• Any scrambled or encrypted transmissions  
According to the Electronic Communications Privacy Act (ECPA), you are subject to fines  
and possible imprisonment for intentionally listening to, using, or divulging the contents of  
such a conversation unless you have the consent of a party to the conversation (unless  
such activity is otherwise illegal). This scanner has been designed to prevent the reception  
of cellular telephone transmissions and the decoding of scrambled transmissions. This is  
done to comply with the legal requirement that scanners be manufactured so they are not  
easy to modify to pick up these transmissions. Do not open your scanner’s case to make  
any modifications that could allow it to pick up transmissions that are illegal to monitor.  
Modifying or tampering with your scanner’s internal components or using it in a way other  
than as described in this manual could invalidate your warranty and void your FCC  
authorization to operate it.  
In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws  
in your area. It is also illegal in many areas (and a bad idea everywhere) to interfere with  
the duties of public safety officials by traveling to the scene of an incident without  
authorization.

About This Manual  
The screen displays used in this manual are representations of what might appear when  
you use your scanner. Since what you see depends on the frequencies and user ID’s for  
your area and the settings you select, you might notice some differences between what is  
in this manual and what appears on your scanner.  
To get the most from this manual, review the contents to become familiar with the basic  
functions available. If you are new to scanning or trunk tracking, be sure to read  
“Understanding Scanning” on Page 7 for a quick background on the technology behind the  
hobby. The first thing you’ll need to do is plug the AC adapter into the scanner. Then you  
need to connect the included antenna to the scanner. See “Installing Your Scanner” on  
Page 15 if you need any help doing this.  
In addition to the information in this manual, the help file included with the free demo  
software includes more instructions and programming planning worksheets that are very  
useful for organizing the information you need to program your scanner. Download this

Understanding Scanning  
UThnisdseercstiotannprdoivnidgesSycouawninthinbagckground on how scanning works. You don’t really need  
to know all of this to use your scanner, but some background knowledge will help you get  
the most from your BC898T.  
Understanding Banks and Channels  
The memory in your scanner is organized into 10 banks of 50 channels each. Each bank  
can contain conventional channels as well as 1 trunking system. For each trunking system,  
each bank can also store 10 groups of 10 talk group ID’s (100 per bank).  
What is Scanning?  
Unlike standard AM or FM radio stations, most two-way communications do not transmit  
continuously. Your BC898T scans programmed channels until it finds an active frequency,  
then stops on that frequency and remains on that channel as long as the transmission  
continues. When the transmission ends, the scanning cycle resumes until the scanner  
receives another transmission.  
What is Searching?  
The BC898T can search each of its 17 bands and up to ten bands together to find active  
frequencies. This is different from scanning because you are searching for frequencies  
that have not been programmed into the scanner. When you select frequency bands to  
search, the scanner searches for any active frequency within the lower and upper limits  
you specify. When the scanner finds an active frequency, it stops on that frequency as long  
as the transmission lasts. If you think the frequency is interesting, you can program it into  
one of the banks. If not, you can continue to search.  
What is CTCSS/DCS?  
Your scanner can monitor systems using a Continuous Tone Control Squelch (CTCSS)  
and Digital Coded Squelch (DCS) system, which allow squelch to open only when the tone  
you have programmed with a specific frequency is received along with a transmission.  
CTCSS and DCS are subaudible tone signaling systems sometimes referred to as PL  
(Motorola’s trademarked term for Private Line). CTCSS and DCS are used only for FM  
signals and are usually associated with both amateur and commercial two-way repeaters.  
These systems make use of a special subaudible tone that accompanies a transmitted  
signal.  
CTCSS and DCS are used for many purposes. In many cases, CTCSS and DCS are used  
to restrict access to a commercial repeater, so that only those units, which transmit the  
correct tone along with their signal can “talk to the repeater.”  
CTCSS and DCS are also used in areas that receive interference where there are several  
stations with output frequencies close to each other. When this occurs, you might hear  
multiple communications at the same time. The stations might even interfere with each  
7
 
other to the point where it is impossible to clearly receive any of the stations. A scanner  
equipped with CTCSS and DCS (like your scanner) can code each received frequency  
with a specific CTCSS or DCS frequency. Then, when you receive multiple signals, you  
only hear the transmission with the CTCSS or DCS tone you programmed. If you do not  
receive the correct tone with a signal, the scanner’s squelch remains closed and you hear  
nothing.  
Local frequency allocation groups set cooperative standards to establish the CTCSS and  
DCS tone for each transmitter (or repeater).  
You can search for the following CTCSS frequencies and DCS codes.

Conventional Scanning  
Conventional scanning is a relatively simple concept. Each group of users in a conventional  
system is assigned a single frequency (for simplex systems) or two frequencies (for repeater  
systems). Any time one of them transmits, their transmission always goes out on the same  
frequency. Up until the late 1980’s this was the primary way that radio systems operated.  
Even today, there are many 2-way radio users who operate using a conventional system:  
8
 
• Aircraft  
• Amateur radio  
• FRS/GMRS users  
• Broadcast AM/FM/TV stations  
• Many business radio users  
When you want to store a conventional system, all you need to know is the frequencies  
they operate on. When you are scanning a conventional system, the scanner stops very  
briefly on each channel to see if there is activity. If there isn’t, the scanner quickly moves to  
the next channel. If there is, then the scanner pauses on the transmission until it is over.  
Simplex Operation  
Simplex systems use a single frequency for both transmit and receive. Most radios using  
this type of operation are limited to line-of-sight operation. This type of radio is frequently  
used at construction job sites, and with inexpensive consumer radios such as GMRS/FRS  
radios. The range is typically 1-8 miles, depending upon the terrain and many other factors.  
Repeater Operation  
Repeater systems use two frequencies: one transmits from the radio to a central repeater;  
the other transmits from the repeater to other radios in the system. With a repeater-based  
system, the repeater is located on top of a tall building or on a radio tower that provides  
great visibility to the area of operation. When a user transmits (on an input frequency), the  
signal is picked up by the repeater and retransmitted (on an output frequency). The user’s  
radios always listen for activity on the output frequency and transmit on the input  
frequency. Since the repeater is located very high, there is a very large line of sight.  
Typical repeater systems provide coverage out to about a 25-mile radius from the repeater  
location.  
What is Trunk Tracking?  
Your BC898T is designed to track the following types of trunking systems.  
• Motorola Type I, Type II, Type IIi, hybrid, SMARTNET, and PRIVACYPLUS analog  
trunking systems, which are extensively used in 800 MHz communication systems.  
• LTR trunking systems  
• EDACS trunking systems  
When tracking these types of systems, you might want to remember these important points:  
Your scanner defaults to monitor Type II systems; however, you can change this if the  
system in your area is different. (The types of systems are discussed below.)  
Your scanner can track more than one trunking system at a time and scan  
conventional and trunked systems at the same time.  
9
 
• The frequencies for many of the 800 MHz public safety systems are listed in the  
National Public Safety Trunked System Frequency Guide included with your BC898T  
scanner.  
Conventional scanning is a simple concept. You enter a frequency used by someone you  
want to monitor into your scanner’s memory. For example, the police in your area might  
transmit on 460.500 MHz, the fire department on 154.445 MHz, the highway department  
on 37.900 MHz, etc. So when your scanner stops on a frequency, you usually know who it  
is, and more importantly, you can stop on a channel and listen to an entire conversation.  
This type of scanning is easy and fun.  
However, as the demand for public communications has increased, many public radio  
users do not have enough frequencies to meet their needs, creating a serious problem.  
Trunking radio systems help solve this problem.  
Trunked Scanning  
While conventional scanning worked great while there were only a few groups wanting to  
use the frequencies, with the advent of smaller, lower-cost radios more and more agencies  
and businesses wanted to take advantage of the utility of 2-way radio. As a result, the  
bands that were used most became full, so new users were not able to take advantage of  
the technology as quickly as they wanted.  
Trunking solved this frequency shortage by allowing multiple groups to use the same set of  
frequencies in a very efficient way. While each type of trunking system operates a little  
differently (see the next few sections), they all work on the same basic premise: even in a  
system with a lot of users, only a few users are ever transmitting at any one time.  
Instead of being assigned a frequency, as with conventional systems, each group is  
assigned a talk group ID. A central computer controls the frequency each group operates  
on...and this frequency selection is made each time a user transmits. So, while on a  
conventional system queries, replies, and follow-ups are all on a single frequency, they  
could each be on completely different frequencies on a trunked system. This semi-random  
frequency assignment made monitoring such a system impossible prior to Uniden’s  
invention of the Trunktracking scanner.  
Not only does your BC898T scan channels like a conventional scanner, it actually follows  
the users of a trunked radio system. Once you know a talk group’s ID, you won’t miss any  
of the action.  
If you are a new scanner enthusiast, you might want to read the first part of this manual  
and use your scanner in conventional mode before you begin trunk tracking.  
Understanding scanning fundamentals and terminology will make trunk tracking much  
easier. If you are already an experienced scanner operator, you might want to go to  
“Programming Trunked Systems” on Page 42 now.

Types of Trunking Systems  
Trunking systems divide a few frequencies among many different users, but the way that  
each system does this is slightly different. This section describes some of the technical  
data behind Motorola, EDACS, and LTR trunked radio systems.  
Motorola Trunking  
While there are different types of Motorola trunking systems, they all use the same basic  
trunking method. The system consists of one control channel plus one or more voice  
channels (typically 10, 20, or 30 total channels). When a user presses Push To Talk (PTT)  
to transmit, their radio first sends their talk group information to the control channel. The  
computer then assigns that talk group to a specific voice channel and transmits that data  
over the control channel. All radios in that talk group switch over to the assigned voice  
channel and the user can begin speaking. This all typically takes place in about a  
second...the person transmitting hears a beep from their radio when the channel is  
assigned and then it is OK to start talking.  
The systems in use are:  
Motorola Type I – the radios send the radio ID, the fleet and subfleet talk group ID to the  
control channel each time they transmit. To program a Type I system, you need to know  
the system’s fleet map. The most common fleet maps are included at the back of this  
manual. You can also find fleet map resources on the web.  
Motorola Type II – the radios only send the radio ID and radio channel code to the control  
channel. The central computer keeps a database of radio ID’s and which talk group is  
assigned to which channel code for each radio, so with this system the user’s radio sends  
only about 1/3 the data as a Type I system with each transmission. Type II systems do not  
use Fleet-subfleet talk groups; instead they use a 5-digit ID for each talk group.  
Type IIi Hybrid — these systems support a mix of both Type I and Type II users. Like Type  
I systems, you must know the system’s fleet map to ensure proper tracking.  
EDACS Trunking  
EDACS trunking works in much the same way as Motorola trunking with a couple of major  
differences. In an EDACS system, each frequency used by the system is assigned a  
Logical Channel Number (LCN) so that less data needs to be transmitted by the control  
channel. Also, talk groups are assigned in an Agency-Fleet-Subfleet (AFS) hierarchy. Also,  
there is one variation of EDACS called SCAT that your BC898T can monitor.  
Logical Channel Numbers – each frequency used by the system is assigned an LCN. This  
information is programmed into each user radio. When a user presses PTT, their radio  
sends their AFS information to the control channel. The computer then assigns that talk  
group to a channel and sends the LCN so that all other radios in that talk group will switch  
to the correct channel. To program an EDACS system in your scanner, you will need to  
11  
 
know both the frequencies used by the system and the LCN for each frequency so that you  
can program the frequencies in LCN order.  
Agency-Fleet-Subfleet – talk group ID’s for EDACS systems are assigned in a way that  
makes it easy to see at a glance the affiliation of the user. Each radio is assigned a 2-digit  
agency identifier from 00 – 15. For example, 01 might be used by the police, 02 by  
ambulance service, 03 by the fire department, and so on. Each agency is then subdivided  
up to 16 times to provide fleet identification, and then 8 more times to identify subfleets.  
For example, the complete AFS for the Police Department West District’s dispatch channel  
might be 01-062. 01 identifies the agency as the police department, 06 identifies the fleet  
as the West district, and 2 identifies the subfleet as the dispatch channel. While these  
assignments are somewhat arbitrary and vary from system to system, there are many  
resources on the web for finding the assignments for most systems. Because of the logical  
hierarchy of the AFS system, your BC898T lets you assign wildcard ID’s that let you, for  
example, use only one ID memory to identify all units in either an agency or a fleet.  
EDACS SCAT – EDACS SCAT (Single Channel Autonomous Trunking) systems operate  
on a single channel and alternate control data with analog voice traffic. While your BC898T  
cannot track ID’s in this system, it can eliminate the control data so that all you hear is the  
voice transmissions when you monitor this type of system.  
LTR Trunking  
LTR (Logic Trunked Radio) systems are trunking systems used primarily by business or  
private communications service providers, such as taxicabs, delivery trucks, and repair  
services. These systems encode all control information as digital subaudible data that  
accompanies each transmission, so there is no separate control channel. Users on an LTR  
system are assigned to specific talk groups, which are identified by the radio as six digit  
numbers.  
These numbers are in the form AHHUUU, where:  
A = Area code (0 or 1)  
H = Home repeater (01 through 20)  
U = User ID (000 through 254)  
When the scanner receives a transmission on a channel set to the LTR mode, it first decodes  
the LTR data included with the transmission. In the ID search mode, the scanner stops on the  
transmission and displays the talk group ID on the display. In the ID scan mode, the scanner  
only stops on the transmission if the LTR data matches a talk group ID that you have  
stored in the bank’s talk group ID list and have not locked out. LTR systems are frequently  
programmed so that each radio has a unique user ID. LTR systems also need to be  
programmed into your scanner in channel order.  
Since many LTR systems use only odd-numbered channel slots, you would program these  
systems using only the corresponding odd-numbered channels in a bank (for example,  
12  
 
you would program a system with channels at 1, 3, 5, and 9 into Trunk 2 channels 51, 53,  
55, and 59).  
Where To Obtain More Information  
By itself, this manual really only provides part of what you need to know to have fun  
scanning – how to program and use the scanner. The two included conventional and  
trunking frequency guides will give you a good head start on the other part of what you  
need to know – what frequencies have interesting content.  
Information On The Internet  
The Internet is a great source for current frequencies and information about scanning.  
Many web sites have lists of frequencies for your area. You can use a search engine to find  
and use them.  
Make a list of the agencies you want to listen to, then look up the frequencies and systems  
used by those agencies. Here are a few useful sites:

Installing Your Scanner  
These guidelines will help you install and use your new scanner:  
• If your scanner receives interference or electrical noise, move the scanner or its  
antenna away from the source. You might also try changing the height or angle of the  
telescoping antenna.  
To improve the scanner’s reception, use an optional external antenna designed for  
multi-band coverage. (You can purchase this type of antenna at a local electronics  
store). If the optional antenna has no cable, use 50-70 ohm coaxial cable for lead-in.  
A mating plug might be necessary for the optional antennas.  
• Use an optional earphone or stereo headset with proper impedance for private  
listening. Read the precautions on the inside front cover of this Owners Manual.  
• Do not use the scanner in high-moisture environments such as the kitchen or  
bathroom.  
• Avoid placing the scanner in direct sunlight or near heating elements or vents.  
For Home Use (Desktop Installation)  
DC 12V  
Power Jack  
Remote Jack  
Antenna Jack  
Telescoping  
Antenna  
Plug  
1. Insert the DC plug end of the included AC adapter into the DC 12V jack on the back of  
the scanner.  
2. Plug the other end of the AC adapter into a standard 120V AC wall outlet.  
3. Plug the included telescoping antenna into the ANT connector on the back of the  
scanner. Then extend the antenna to its full height.  
Note: For frequencies higher than 406 MHz, shortening the antenna might improve the  
reception.  
4. Use the scanner’s desktop stand for a better viewing and operating angle.  
15  
 
Adapter Safety Feature  
The AC adapter included with the scanner might be equipped with a polarized line plug —  
a plug with one blade wider than the other. This plug fits into a power outlet only one way.  
If you are unable to insert the adapter’s plug into an AC outlet, try reversing the plug.  
Using An Optional External Speaker/Earphone/Headphone  
LINE Jack  
External Speaker Jack  
For private listening or for listening in a noisy area, you can plug a 1/8-inch (3.5mm) mini-plug  
earphone’s or headphone’s or monitor speaker’s (not included) cable into the EXT SP jack  
on the front of the scanner. This automatically disconnects the scanner’s internal speaker.  
Listening Safely  
To protect your hearing, follow these guidelines when you use an earphone or  
headphones.  
• Do not use an earphone to listen to the WX alert siren or when in SAME alert mode.  
The alert tone’s volume is not adjustable and damage to your hearing could occur.  
• Do not listen at extremely high volume levels. Extended high-volume listening can lead  
to permanent hearing loss.  
• Set VOLUME to the lowest setting before you begin listening. After you begin listening,  
adjust VOLUME to a comfortable level.  
• Once you set VOLUME, do not increase it. Over time, your ears adapt to the volume  
level, so a volume level that does not cause discomfort might still damage your  
hearing.  
Using An Optional Tape Recorder  
You can use a standard tape recorder or a VOX (Voice Operated Control) tape recorder  
with the scanner. The tape recorder you use must have a remote jack. You need a cable  
with a 1/8-inch (3.5 mm) plug (not included) to connect the tape recorder to the scanner.  
You can get a cable from your local electronics store.  
16  
 
 
Connect one end of the cable to the tape recorder’s remote jack, then connect the other  
end of the cable to LINE on the front of the scanner.  
Remember! You must program a channel for tape recording before you can record it. See  
Using the Demo Software  
You can operate your scanner using a personal computer and the free demo software  
available at http://www.uniden.com.  
If you have installed the software and it is running, select Help by right clicking anywhere  
on the opening screen. A selection popup appears. Move the cursor to Help. BC898TSS  
Help appears. Then click on BC898TSS Help.  
To turn on the computer control feature and set the baud rate, hold down RMT on the front  
of the scanner until you hear two short beeps, turn the rotary tuner until the baud rate you  
want to select appears, then press E.  
To cancel computer control, hold down RMT until you hear two short beeps, turn the rotary  
tuner until OFF appears, then press E.  
Installing The Software  
Download the software, then double-click on the install package to begin installation. The  
BC898T SS Install program installs the software. You must install the software to use the  
scanner with your computer.  
After you install the BC898T SS Install program, start it by double clicking on the desktop  
icon or by selecting it in the Start Programs list.  
You can upgrade the included software to a full version by purchasing a registration key at

Installing The Scanner In a Vehicle  
Mounting the Scanner  
1. Select a location in your vehicle to mount the scanner. Avoid a location that could inter-  
fere with your driving. In a passenger car, the ideal location is underneath the dash-  
board on the passenger side.  
Warning: Make sure there are no obstructions such as wires or an air bag behind the  
mounting location you select. Use the shortest mounting screws that will securely hold  
the mounting bracket on the mounting location you select. If you are not sure if the  
mounting location is safe and free of obstructions, check with your vehicle’s dealer.  
2. Use an optional mounting bracket as a template for marking the location for the mount-  
ing screws.  
Note: If there are screws already holding the dashboard, you can use the same screw  
holes to mount the bracket.  
3. Drill the necessary holes and secure the mounting bracket in  
place using the screws provided with the bracket.  
4. Mount the scanner to the bracket only after the wiring has  
been connected to the scanner’s rear panel.  
Connecting the Antenna Plug  
Connect an optional mobile antenna plug into the ANT connector on the back of the  
scanner. (For more information on antenna installation, please refer to the instruction  
guide that came with your antenna.)  
Connecting the DC Power Cord  
If you are not experienced in connecting accessories to your vehicle’s fuse box, please  
consult your vehicle’s dealer for advice on proper installation before completing the steps  
below.  
Installing a Temporary Power Cord  
Warning: Do not use the cigarette lighter power cord in a positive ground vehicle.  
Use an optional cigarette lighter power cord for an easy, temporary installation.  
Plug one end of the cigarette lighter power cord into your vehicle’s cigarette lighter jack,  
then plug the other end into the DC 12V jack on the back of the scanner.  
18  
 
Installing a Permanent Power Cord  
1. Check the vehicle’s battery connections to determine which battery terminal (positive  
or negative) is grounded to the engine block or chassis. Most of today’s vehicles use a  
negative ground. If your vehicle has a negative ground, follow the steps below.  
Otherwise, consult your vehicle’s dealer for advice on installing negative ground acces-  
sories in your vehicle.  
2. Connect an optional DC power cord’s RED wire to the accessory contact in your  
vehicle’s +12 VDC fuse box.  
3. Connect the DC power cord’s BLACK wire to the negative side of the vehicle (usually  
the chassis).  
4. Insert the DC plug into the DC 12V jack on the back of the scanner.

Basic Operation  
Basic Operation  
BTuarsnicinOgpOenratthioenScanner  
Turn VOLUME clockwise to turn on the scanner, or counterclockwise until it clicks to turn it  
off.  
Setting the Squelch  
Your scanner’s squelch control acts like a gate to reduce or eliminate noise from received  
signals. Turning SQUELCH clockwise raises the gate so high that only very strong signals  
can get through, while turning SQUELCH counterclockwise lowers the gate so that  
everything can get through — noise, weak signals, and strong signals.  
To set the squelch, you must first set the scanner to its manual mode and the scanner  
must not be receiving a signal.  
Follow these steps to set the scanner’s squelch.  
1. Adjust VOLUME to a comfortable listening level.  
2. Repeatedly press MANUAL until you do not hear a signal.  
3. Turn SQUELCH fully clockwise.  
4. Turn SQUELCH counterclockwise until you hear a hiss.  
5. Turn SQUELCH back clockwise just until the hiss stops. This sets the squelch so that  
only clearer signals can get through.  
You can change the squelch setting, if necessary, to provide better performance in your area.  
Using the Rotary Tuner  
Use the rotary tuner to:  
• Rapidly and precisely select frequencies or channels in the conventional or trunking  
mode.  
• Select a CTCSS tone during CTCSS programming in the conventional or trunking  
mode.  
• Scroll through scan and lockout lists in the trunking mode.  
To use the rotary tuner, press MANUAL to stop scanning if necessary. Then, if the green  
LOCK LED is on, press LOCK to unlock the rotary tuner. Then turn the rotary tuner to  
select frequencies, channels, or CTCSS tones, or scroll through scan and lockout lists.  
To program a channel, repeatedly press FREQ/CHAN until the CHAN LED lights. Then  
turn the rotary tuner to select the channel. To program a frequency, repeatedly press  
FREQ/CHAN until the FREQ LED lights. Then turn the rotary tuner to select the frequency.  
20  
 
 
Note: You can also use the keypad to enter a frequency.  
Press E to program the frequency into the channel you selected.  
Using the Frequency/Channel Mode Selector  
Repeatedly press FREQ/CHAN to switch between channel and frequency mode. When  
the CHAN LED is on, you can use the rotary tuner to step rapidly through channels. When  
the FREQ LED is on, you can use the rotary tuner to tune frequencies quickly and  
accurately.  
Using the Lock Key/LED  
Press LOCK to enable or disable the rotary tuner. When the LOCK LED is on, the rotary  
tuner is locked. This prevents accidentally changing the displayed channel and frequency  
while monitoring a transmission.  
Manually Selecting a Channel  
To manually select a channel, press MANUAL, enter the channel’s number using the  
keypad, then press MANUAL again. The channel’s number and any frequency stored in  
the channel appears.  
Scanning Programmed Channels  
Before you start to scan, you must first program channels. See “Programming” on Page 35  
and “Programming Conventional Channels” on Page 39 (for conventional channels) or  
“Programming Trunked Systems” on Page 41 (for trunking systems) for complete  
instructions.  
To begin scanning, simply turn on the scanner or, if the scanner is not currently scanning,  
press SCAN.  
The scanner checks each system you have programmed that is not locked out and stops if  
there is activity. SCAN scrolls across the display, right to left.  
When the scanner receives a signal on a programmed channel, it stops on that channel  
and displays the channel information.  
The bank indicators A – J selected for scanning appear, and the bank you are currently  
monitoring flashes. You can deselect banks from active scanning by pressing that bank’s  
key (A-J). The indicator for each deselected bank turns off, and the scanner does not scan  
that bank’s channels.  
Note: One bank must always be active. You cannot deselect all ten banks at the same  
time. If you try to turn off all the banks, the scanner automatically selects the first bank.  
To restore a bank to active scanning, press the bank’s letter. The bank’s indicator appears.  
21  
 
Press MANUAL to stop on a channel while scanning. Press SCAN to resume scanning.  
Locking/Unlocking Banks  
When you are scanning conventional banks, the scanner displays the digit corresponding to  
all unlocked banks. To lock out a bank so that the scanner does not scan its channels, press  
the letter that corresponds to the bank. The bank’s letter disappears from the display.  
To unlock locked-out banks, simply press that bank’s letter again. The bank’s letter  
appears on the display and the scanner includes that bank when scanning.  
Note: You cannot lock out all banks. One bank must be unlocked at all times.  
Locking/Unlocking Channels  
To lock out a channel so that the scanner does not stop on it while scanning, press L/O  
when the scanner is stopped on that channel, or manually select the channel and press L/O.  
To unlock the channel, manually select it and press L/O again.  
Restoring All Locked Out Channels  
You can restore all locked-out channels in a bank only when the bank is selected for scan.  
Follow these steps to restore all locked-out channels in a bank.  
1. If you de-selected the bank, press SCAN then press the bank’s letter.  
2. Press MANUAL.  
3. Hold down L/O for about 2 seconds. The scanner beeps twice and unlocks all  
channels.  
Priority Scanning  
When priority scan is turned on, the scanner checks the priority channels in the unlocked  
banks every 2 seconds between transmissions. If a signal is present on a priority channel,  
the scanner switches to monitor that transmission, even if it had been stopped on another  
channel. One channel in each bank is designated as the priority channel.  
To turn priority scan on or off, press PRI. PRIORITY appears (if priority scan is on) or  
disappears (if priority scan is off).  
Note: If all priority channels in unlocked banks are locked out, P CH LOC0 T appears  
when you try to turn on the priority scan mode.  
22  
 
 
Changing the Priority Channel  
You cannot eliminate the priority channel, but you can change it to any of the 50 available  
channels in each bank. Follow these steps to change the priority channel.  
1. Press MANUAL.  
2. Use the keypad to enter the channel number for the new priority channel.  
3. Press MANUAL.  
4. Hold down PRI for about 2 seconds.  
The scanner beeps twice and the priority channel changes to the one you selected.  
Using the Dimmer  
Hold down DIM for about two seconds to change the display’s brightness.  
Trunk Scanning Options  
When you are scanning a trunked system, there are several trunking-only options  
available to you. This section outlines these options.  
Searching for Active Talk Groups (ID Search)  
If you want to hear all activity on a trunked system, use the ID search mode by pressing  
SCAN then SRC. SEARCH appears and the BC898T stops on every active talk group,  
regardless of whether you have programmed it into your scanner. This makes it easy to  
find unknown talk groups.  
Note: If you have not yet programmed any talk group ID’s into the scanner, this is the only  
trunk scanning mode available.  
Searching Only Stored Talk Groups (ID Scan)  
To scan only those talk groups you have stored into your scanner, press SCAN. When one  
of the talk groups you have stored becomes active, the scanner switches to that  
transmission and displays the ID number for that talk group.  
Note: You must store at least 2 talk group ID’s in the system for ID scanning to work.  
Monitoring Talk Group ID’s  
To see all the talk group ID’s that are active on the system, while monitoring a trunked  
system press SCAN. The scanner stops trunking the system and instead holds on the  
system’s control channel. You hear the control data and the scanner displays every talk  
group ID as it becomes active in the system. To resume trunk tracking, press SCAN again.  
23  
 
Holding On a Single Talk Group  
To hold on an active talk group when scanning or searching, press HOLD U. The BC898T  
stops scanning and holds on the current trunking system. It only receives transmissions on  
the talk group that was active when you pressed HOLD U.  
To select a talk group to hold on when that group is not active, while ID scanning or ID  
searching the system, press HOLD U. Then, either enter the ID or (if you have stored the  
ID) scroll to the ID you want to hold on.  
Locking Out Talk Groups  
Like conventional scanning, you can lock out unwanted talk group traffic on trunking  
systems. This is particularly important if you are ID searching a trunking system, as many  
systems share both voice traffic (that you usually want to hear) with some data traffic from  
water meter systems, door alarms, traffic signals and other data sources that you don’t  
want to hear. You can lock out up to 200 talk group ID’s at the same time.  
To lock out a talk group, press L/O when the scanner stops on that group. Or, if you have  
stored the talk group in an ID list, select that ID and press L/O.  
Reviewing Locked Out Talk Group ID’s  
You can confirm which talk group ID’s are locked out in the scanner.  
To review locked out talk group ID’s, hold down L/O for about 2 seconds. The locked-out  
talk group ID’s appear.  
Restoring All Locked Out Talk Group ID’s  
To restore all locked out talk group ID’s, hold down L/O for about 2 seconds.  
EDACS Blockout  
This is a powerful form of lockout that is only available for EDACS systems. EDACS  
Blockout lets you lock out entire agencies or fleets, not just individual talk groups.  
To use blockout, while scanning an EDACS system, press HOLD U.  
Setting the Attenuator  
If you are near a very strong signal source, the signal can overload the scanner’s RF front  
end, causing poor audio quality or missed reception. Repeatedly press ATT until ATT  
appears (to turn the attenuator on) or until ATT disappears (to turn the attenuator off).  
ID Lockout  
Like conventional scanning, it’s possible to lock out unwanted traffic. This is particularly  
important in trunked systems because in many areas water meters, door alarms, traffic  
signals, and other mechanical devices are assigned ID’s just like other users. Also some  
24  
 
departments scramble or encrypt their communications, and you might want to lock out  
these unintelligible transmissions.  
To lock out an ID, press L/O when the ID appears. The ID is locked out, and the next active  
ID appears. You can lock out up to 200 ID’s.  
Note: If you lock out an ID in search mode, it is also locked out in scan list mode.  
Conversely, if you lock out an ID while in scan list mode, it is locked out in search mode.  
Restoring a Single ID  
Follow these steps to unlock a single ID.  
1. Hold down L/O until you hear two short beeps.  
2. Use either the rotary tuner or HOLD U or LIMIT V to select the ID you want to unlock.  
3. Press L/O. The ID is unlocked and the next locked ID appears.  
4. Press SRC to return to the search mode.  
Restoring All ID’s  
Follow these steps to unlock all locked out ID’s at once:  
1. Hold down L/O until you hear two short beeps.  
2. Hold down L/O for about 2 seconds to unlock all the ID’s at once.  
Note: If you unlock all the ID’s, Non appears. Press SCAN to scan the ID’s stored in  
your scan lists or press SRC to return to the search mode.  
3. Press SRC to return to the search mode.  
Searching Tips  
ID Delay Mode  
Use the DELAY key to select the delay mode if it’s not active. This mode holds an ID for 2  
seconds while you wait for a reply. In a trunked system, you can set a delay for each bank.  
Other groups might use the system, but your scanner will only look for the ID in the display.  
Note: If you consistently miss responses while in ID delay mode, you might need to  
change the default system type or change the fleet map you are using.  
ID Hold Mode  
Press HOLD U to hold on a particular ID in the display. This is where the trunk tracking  
effect is really noticeable. You can hold a specific talk group, such as fire department on-  
scene operations, no matter which frequency the group uses.  
25  
 
ID Monitor Mode  
To enter manual mode for a conventional system in a bank selected for a trunked system,  
press MANUAL. All active talk group ID’s appear in succession.  
Note: Locked out ID’s appear during ID monitor mode.  
Scan Lists  
You can program conventional or trunking frequencies into any of your scanner’s banks  
When you designate a bank as a trunk tracking bank, your scanner sets up 10 scan lists  
(A –J), which are simply lists used to store your favorite ID’s. Each list can contain up to 10  
ID’s, so you can store a total of 100 ID’s for each trunk tracking bank (1000 if you use all  
banks as trunking banks!). Scan lists help you organize the trunking system users into  
categories. For example, you might use List A for police ID’s, List B for fire department  
ID’s, List C for emergency medical service ID’s, etc. Once ID’s are stored in lists, you can  
scan them like you scan conventional frequencies. You can program your scan lists either  
manually or during trunking search mode.  
You can use the rotary tuner to scroll through the ID’s in your scan lists.  
26  
 
Searching  
Searching  
Chain Search  
Your scanner’s chain search feature lets you discover new active frequencies in your area.  
To use chain search, first program one or more chain search ranges (see “Setting and  
Saving a Chain Search Range” below). Then, select one or more chain search ranges to  
search (see “Selecting Chain Search Ranges” below). Then press SRC (see “Using Chain  
Search” below). The scanner searches all frequencies within the chain search range or  
ranges you selected.  
Setting and Saving a Chain Search Range  
You can save up to 10 chain search ranges in your scanner.  
1. Press MANUAL to stop scanning.  
2. Press SRC.  
3. Press HOLD U. HOLD appears.  
4. Select the memory location where you want to save a chain search range by pressing  
its bank key (A-J). If there is a chain search range already stored in that memory loca-  
tion, the lower and upper frequencies of that chain search range flash.  
5. Use the keypad to enter the lower frequency of the chain search range, then press E  
on the keypad or LIMIT V. (Press . to enter the decimal point).  
6. Use the keypad to enter the upper frequency of the chain search range, then press E  
on the keypad or LIMIT V. (Press . to enter the decimal point).  
Selecting Chain Search Ranges  
By default, your scanner only searches one chain search range at a time. However, you  
can select more than one chain search range and the scanner will search each range you  
select. To select chain search ranges, press the bank keys (A-J) associated with the  
ranges you want to select. When you turn on chain search, each time you press a bank  
button, that chain search range is turned on or off and its letter appears or disappears from  
the display.  
Using Chain Search  
To use chain search, press SRC then press the bank keys (A-J) for the chain search range  
or ranges you want to search.  
To change the step increment during a chain search, repeatedly press STEP to select the  
increment you want. The step increment you selected flashes. If you select the default step  
increment for that frequency, its indicator stops flashing.  
Holding On An Active Frequency  
To hold on the current frequency, press HOLD U.To resume searching, press SRC.  
27  
 
 
Setting Data Skip  
The scanner normally stops on any frequency with activity, and remains there until either  
the activity stops or you press SRC to resume scanning. However, some signals are  
identifiable by the scanner as data signals, and you can set the scanner to automatically  
skip these channels.  
Note: Even with this option turned on, the scanner might pause for a couple of seconds on  
data transmissions before resuming.  
To turn on data skip, press DATA.  
Skipping Frequencies  
If a particular frequency continues to interrupt search scanning, you can set the scanner so  
it skips the frequency. To skip over a frequency, press L/O when the scanner is stopped on  
a frequency you want to skip.  
Notes:  
• You can program up to 100 skip frequencies. The 101st skip frequency entered causes  
the first skipped frequency to unlock.  
• If all frequencies in the search range are set to skip, a beep sounds and it moves to  
search hold mode. To resume searching:  
a. Unskip all skipped frequencies  
—- OR —  
b. Select a different search frequency range.  
To unskip all skipped frequencies, hold down L/O for about 2 seconds in search hold  
mode.  
Storing Found Frequencies  
If you find a frequency you want to save into a channel, follow these steps.  
1. Press E or SEND when the scanner is stopped on that frequency. All the bank indica-  
tors flash.  
2. Select the bank where you want to send the frequency. The display alternates between  
the frequency you are sending and the lowest available channel in the bank. If there is  
no free channel in the bank, the scanner automatically selects the first channel in the  
bank you selected.  
3. Press E.  
Note: If you have already stored this frequency, the scanner displays a warning and the  
channel where the frequency is stored. To store the frequency anyway, press E again.  
28  
 
Automatically Storing Frequencies  
During searching, you can have the scanner automatically store active frequencies into a  
bank you choose. Once the search begins, AutoStore will automatically program active  
frequencies into the available channels of the bank(s) you select. For more information  
about your scanner’s search feature, see “Searching” on Page 27.  
Note: You must program a chain search range for auto store to work.  
1. Press MANUAL to stop scanning.  
2. Press AUTO. All the bank letters flash and AUTO appears.  
3. Press the bank keys (A-J) where you want to store the frequencies the scanner finds.  
The bank letter(s) you select stop flashing.  
If the bank you selected has no empty channels, FULL appears for about 3 seconds  
and the scanner sounds an error tone. You must either delete frequencies in the bank  
or select another bank.  
4. Press SRC to start AutoStore.  
AutoStore stops automatically when all available channels in the selected bank(s)  
have been programmed.  
5. Press MANUAL to exit AutoStore and return to the manual mode.  
Notes:  
To exit AutoStore before all the available channels in the selected bank(s) are pro-  
grammed, press MANUAL twice.  
To ensure that you catch most active frequencies for the band, you should allow  
AutoStore to continue through at least a few complete sweeps of the band. Depending  
on the types of services, some occasionally active frequencies might not have activity  
for minutes or hours at a time.  
Setting Subaudible Tones for Searching  
You can set the scanner to only stop on transmissions that either have no subaudible tone  
or include a specified CTCSS or DCS tone during searches. This setting affects all search  
ranges. For this feature to work, you need to turn on the tone mode (see “Setting the  
1. Press PRI to turn off priority scan.  
2. Hold down CTCSS/DCS for about 2 seconds. CTCSS and DCS blink and the scanner  
searches for CTCSS or DCS tones. When the scanner finds a CTCSS or DCS tone,  
the frequency blinks.  
29  
 
Attenuating All Search Ranges  
If you are near a strong RF source, you might need to attenuate the input signal in order to  
search properly. Repeatedly press ATT until ATT appears (to turn on attenuation) or until  
ATT disappears (to turn off attenuation).  
Setting Delay For All Search Ranges  
You can set the scanner to have a 2-second delay after the end of a transmission before  
searching resumes. This slows searching, but helps you prevent missing replies on a  
frequency. To turn on this option for all search ranges, select the channel where you want  
to add a delay then press DELAY.  
Searching a Trunked Bank  
Before you search a trunked bank with your scanner, consider the following:  
• You can only trunk track one bank at a time.  
• Repeatedly press TRUNK to toggle between the conventional and the trunk tracking  
modes.  
• Press DATA while in the trunk tracking mode to review which bank is currently in use.  
The appropriate bank icon flashes at the top of the display. Press DATA again to turn  
off review.  
If you have programmed frequencies for a trunked system in one or more of the 10  
available banks and you are in conventional mode, follow these steps to begin trunk  
searching.  
1. Press TRUNK then press SCAN.  
2. Press a bank key (A-J) to select the trunked bank you want. For example, press B.  
Note: You will see the frequencies appear quickly as your scanner looks for the data  
channel, which controls the system.  
3. Once the data channel is acquired, the scanner starts to trunk track. Talk group ID’s,  
which represent different service groups, appear.  
4. Press TRUNK again to return to conventional mode.  
While searching, you won’t know exactly to whom the ID’s are assigned until you listen  
awhile or until ID lists are available in frequency guides or on internet sites. However, it  
usually only takes a few minutes to figure out police, fire, and emergency medical  
personnel. Other ID’s might take some time, but determining who each ID represents is  
half the fun of trunk scanning!  
30  
 
Searching for CTCSS/DCS Tones  
You can use the CTCSS/DCS tone search mode to determine if the frequencies in your  
area are transmitted with associated tones. If the scanner finds a CTCSS or DCS tone, the  
type of tone and the frequency flash on the display. Then, if you store that frequency into a  
channel, the tone is also stored in the channel.  
Notes:  
You can search for CTCSS/DCS tones in scan mode, manual mode, or chain search  
mode. You cannot search for CTCSS/DCS tones while the scanner is scanning a  
priority channel.  
You might find frequencies that do not have a tone associated with them. This might be  
because CTCSS or DCS tones are not being transmitted.  
1. If necessary, press PRI to turn off priority scan.  
2. Hold down CTCSS/DCS until you hear two short beeps. CTCSS and DCS appear and  
begin to flash. If there is a break before a tone is identified, your scanner searches  
where it left off when the transmission begins again. If a CTCSS or DCS tone is found,  
the type of tone (CTCSS or DCS) and the frequency flash.  
To exit tone search, press CTCSS/DCS.

Using Weather Alert (SAME)  
Important: Your scanner has been primarily designed to be a radio scanner. While it  
Using Weather Alert (SAME)  
incorporates weather alert as one feature, we strongly recommend that you not use the  
scanner as your sole means for receiving emergency alerts. Your local electronics retailer  
carries several weather radios specifically designed for this function.  
Your scanner allows you to either search for a local NOAA weather broadcast, or be set  
to alert when a SAME weather alert is broadcast on a NOAA channel.  
Turning Weather Alert On/Off  
In weather alert mode, your scanner functions as a severe weather warning radio. This is  
especially useful when your area is expecting severe weather conditions late at night.  
When you set the scanner to weather alert mode, it emits a loud siren and displays  
information about the weather alert whenever your local NOAA weather station transmits a  
severe weather emergency tone.  
Follow these steps to turn on weather alert:  
1. Press WX to find your local weather station.  
2. Press HOLD U.  
3. Hold down ALERT for about 2 seconds. ALERT appears.  
The scanner’s volume is muted until the warning tone sounds.  
Your scanner now functions as a weather alert radio, waiting to receive a severe weather  
emergency tone. When your scanner receives the emergency tone and a SAME event  
code from your local NOAA weather station, it responds with a loud siren at maximum  
volume (regardless of the volume control setting) and displays information about the alert.  
You might see any of the following information during a weather alert:  
L1 – Warning  
L2 – Watch  
L3 – Advisory  
TST Test  
The siren will continue until the emergency tone stops transmitting.  
To cancel the siren, press WX. ALERT disappears.  
Searching for a Weather Broadcast  
You can use the BC898T to search for your local NOAA weather channel.  
To search for a weather broadcast, press WX to find an active weather channel in your area.  
WX appears.  
32  
 
You might receive more than one weather station in your area. When you press WX, your  
scanner finds the first active transmission. If a transmission seems weak or distant, press  
WX again to find a clearer station.  
Notes:  
• Weather scan does not resume automatically. You must press WX again to start the  
weather scan again. In some parts of the country, you might not be able to monitor  
weather transmissions, such as in low-lying areas. Normally a higher location will  
improve the reception.  
• NOAA broadcasts are continuous broadcasts. You will only lose reception if you move  
out of a coverage area. If the signal is lost, the scanner resumes searching for a  
weather transmission.  
Programming a FIPS Code  
SAME (Specific Area Message Encoding) was adopted late in the last century to replace  
the wide-area alerts previously used. Weather alerts today are preceded by a digital  
packet that identifies not only the type of alert, but also the geographic location for the  
alert. Thus, it is possible for a weather broadcast that can be received across many  
counties to be targeted to a single county. To specify a county, SAME uses a standard  
established by the US Census bureau, called FIPS.  
The format of a FIPS code is:  
DSSCCC  
Where  
D = area subdivision (0=entire area)  
SS = State code (00=all states)  
CCC = County code (000=all counties)  
For example, the FIPS code for Tarrant County, Texas is: 048439  
(48=Texas; 439=Tarrant County).  
Some counties are further subdivided, in which cases, the first digit will be 0 for all  
subdivisions in the county and each subdivision will be labeled 1-9.  
To program your scanner to alert you when the weather service issues an alert, you must set  
the scanner to the alert mode, and then leave the scanner monitoring the weather service.  
You cannot scan and monitor for weather alerts at the same time. To limit alerts to a specific  
area, you must also program in the FIPS code(s) for the area(s) you want to receive alerts for.  
The scanner can be set to either alert for all areas, or only the areas you have programmed.  
You can get FIPS codes for your area by calling the National Weather Service at  
1-888-NWR-SAME or visit their web site at http://www.nws.noaa.gov/nwr/indexnw.htm.  
33  
 
1. Hold down WX for about 2 seconds to turn on weather alert.  
2. Hold down E for about 2 seconds.  
If the scanner has not been set to alert for any FIPS code, ____ appears. If the scanner  
is set to alert for all FIPS codes, ALLFIPS appears. If the scanner is set to alert only for  
the area you programmed, F1 appears.  
3. Turn the rotary tuner or repeatedly press HOLD U or LIMIT V to enter a FIPS code  
(1 through 15). Then enter the FIPS code and press E.  
To set the scanner so it sounds an alert tone when it receives any FIPS code, turn the  
rotary tuner or repeatedly press HOLD U or LIMIT V to move ALLFIPS to F1. To set  
the scanner so it sounds an alert tone when it receives only one of the FIPS codes you  
programmed, turn the rotary tuner or repeatedly press HOLD U or LIMIT V to select  
F1 to F15. Then press E.  
4. When you finish entering FIPS codes, press E.

Programming  
PThreogBCra8m98mT ihnags 500 memory channels, each of which can be programmed to store one  
frequency. The channels are divided into ten 50-channel banks, useful for storing similar  
frequencies in order to maintain faster scanning cycles.  
You can use the keypad and rotary tuner to program your scanner. You can also use the  
scanner’s AutoStore feature to automatically program channels, and transfer a frequency  
you already programmed from another channel to a channel you select.  
Notes:  
• The information in this section covers basic steps for programming frequencies and  
channels. For specific information about programming conventional channels, see  
gramming trunked systems, see “Programming Trunked Systems” on Page 41.  
• Before you start to program your scanner, we recommend you download the demo  
software and use the worksheets in the software’s help files to help you organize the  
information you want to program.  
Transferring a Programmed Frequency  
You can send any frequency to another channel. To transfer a frequency, select a channel  
with the frequency you want to assign to a different channel. Then press SEND. All the  
bank indicators flash. If you have programmed CTCSS or DCS tones, they also appear  
when you press SEND.  
Transferring a Frequency to the First Available Channel In a Bank  
1. Select the bank where you want to send the frequency. For example, press D.  
The display alternates between the frequency you are transferring and the bank’s low-  
est available channel.  
2. Press E on the keypad to transfer the frequency to the new channel. The scanner  
moves the frequency from the old channel to the new channel.  
3. To cancel the transfer before it is complete, press SEND.  
Transferring a Frequency to a Specific Channel  
1. Use the keypad to enter the channel where you want to send the frequency. (For  
example, press 9 and 4 on the keypad to send the frequency to Channel 94).  
2. Press HOLD U.  
The display alternates between the frequency you are transferring and the frequency in  
the new channel.  
3. Press E to complete the transfer.  
The frequency is now stored in the new channel, and the old channel is empty.  
4. To cancel the transfer before it is complete, press SEND.  
35  
 
 
Duplicate Frequency Alert  
If you enter a frequency already stored in another channel, the scanner beeps and the  
other channel appears. Press . on the keypad to start again or press E again to store the  
frequency in both channels.  
Deleting a Stored Frequency  
To delete a stored frequency, press 0 then press E. Channels with no frequencies are  
automatically locked out.  
Programming a Channel With a CTCSS/DCS Tone  
1. Press MANUAL.  
2. Press CTCSS/DCS.  
3. Select the channel you want to program then press E. If you have already programmed  
a CTCSS or DCS tone, the frequency for the tone blinks. Otherwise, 000.0 HZ blinks.  
4. Enter a CTCSS tone.  
a. Use the keypad, rotary tuner, or HOLD U or LIMIT V to select the tone.  
b. Then press E.  
Notes:  
• If you make a mistake while entering a tone with the keypad, press . on the keypad  
twice and enter the tone again.  
• Make sure FREQ is lit before turning the rotary tuner to select a frequency.  
5. To cancel CTCSS mode, press CTCSS/DCS or MANUAL. The CTCSS indicator and  
displayed tones are turned off but not deleted.  
36  
 
Programming Tips  
• Since weather transmissions are continuous, do not program a weather frequency into  
any of the scanner’s channels. To listen to a weather transmission, press WX to select  
the weather information band instead.  
• Group similar frequencies into adjacent channels. For example, program police fre-  
quencies in channels 1 through 50 and fire/emergency into channels 51 through 100,  
and so on.  
• Put the frequency you listen to the most or the most important frequency into a priority  
channel.  
To quickly program a series of channels, start with the lowest number channel. For  
example, when you are programming five new frequencies into Channels 4 through 8,  
start with Channel 4. After you finish programming a channel, press MANUAL or  
HOLD U to go to the next higher channel.  
• Record channels and frequencies in some convenient place in case the scanner’s  
memory is lost.  
Setting the Delay Mode  
A delay can be set for each programmed channel so that when scan or search stops on a  
channel there is a brief pause before the scanning cycle resumes. Delay must be set for  
each programmed channel, and it can be set when your scanner pauses during a scan or  
when manual mode is selected.  
Setting Delay in Scan or Search Mode  
1. Press SCAN or set a search range then press SRC.  
2. When your scanner stops on a channel, press DELAY. DELAY appears. Scanning  
resumes two seconds after the transmission ends.  
Setting Delay in Manual Mode  
1. Press MANUAL.  
2. Use the keypad or rotary tuner to select a channel.  
3. Press DELAY. DELAY appears. The scanner pauses on the channel when a transmis-  
sion is received.  
37  
 
Recording Transmissions  
You can set any channel for recording while scanning. Then, if your scanner stops on a  
channel you have designated for recording, the connected tape recorder begins to record  
the audio.  
However, before you can use this feature, you must connect a tape recorder to your  
scanner. For information about attaching a recorder to your scanner, see “Using An  
To program a channel for tape recording:  
1. Use the keypad or rotary tuner to select the channel you want to record.  
2. Press LINE. LINE appears indicating that the channel will be recorded if you connected  
a tape recorder to your scanner.  
3. Repeat these steps to select other channels for recording.  
To record a channel, press SCAN. When your scanner stops on a channel and LINE  
appears, the channel is recorded.  
To turn the record feature off for a channel:  
1. Use the keypad or rotary tuner to select the channel you do not want to record any-  
more.  
2. Press LINE. LINE turns off and the channel is not recorded.  
Data Skip  
A scanner will normally stop on any transmission it receives. This means the BC898T will  
stop on data signals and unmodulated transmissions. You can automatically skip many of  
these types of transmissions during searches. Repeatedly press DATA until DATA appears  
(to activate the data skip feature) or until DATA disappears (to deactivate the data skip  
feature).  
When data skip is active, your scanner might pause momentarily on an unwanted signal  
but will resume searching in 2 or 3 seconds.  
Frequency Skip  
If a particular channel continues to interrupt search scanning, you can set your scanner so  
it skips the frequency. To skip a frequency, press L/O.  
Note: You can program up to 100 skip frequencies. If you try to program more than 100  
skip frequencies, additional frequencies you program cause the first skipped frequency to  
unlock.  
38  
 
 
Programming Conventional Channels  
Each of the scanner’s banks can hold a mix of conventional channels plus one trunked  
Programming Conventional Channels  
system. This section describes how to store known frequencies into conventional  
channels.  
You might want to gather all information about the systems you want to monitor before you  
start to program the scanner. The “Conventional Scanning Worksheet” included in the help  
file included in the demo software (download at http://www.uniden.com) makes this easy.  
The first few sections are intended to be performed in the order indicated if you are  
entering information the first time. If you are editing existing information, manually select  
the channel then follow the steps in the appropriate section to access the information you  
want to change.  
Programming conventional channels is easy - just select a channel to program, enter the  
frequency, then press E.  
Important: Do not use this method to program trunked systems. They require additional  
information to scan correctly. See “Programming Trunked Systems” on Page 41 for more  
information.  
Changing the Frequency Step  
The channel frequency step option controls the frequency step size used when you manually  
tune up or down from the frequency stored in the channel. Your BC898T is preprogrammed  
with the most common step sizes for each band, so you seldom need to change this  
setting. To change the frequency step, press MANUAL then repeatedly press STEP until  
the frequency step you want flashes.  
Note: If you select a 6.25 kHz step for the 150.0000 through 161.9999 MHz frequency  
range, the scanner will actually use a 7.5 kHz frequency step to match the FCC band plan  
for this range. However, the scanner’s display will show 6.25 kHz as the selected step.  
Setting the Modulation Mode  
Radio transmissions are modulated in several different ways.  
The BC898T is able to demodulate the most common transmission types. Your scanner  
has the most common modulation mode preset for each band, so you seldom have to  
change this option. However there are occasional services that use a modulation mode  
that is not standard for that band.  
To change the modulation mode, press MANUAL then repeatedly press MODE until the  
modulation mode you want flashes.  
39  
 
 
Setting Priority Channels  
You can set one conventional channel in each bank as a priority channel. When you turn  
on the priority scan option (see “Priority Scanning” on Page 22), the scanner automatically  
checks these channels every 2 seconds to see if there is activity. If there is, the scanner  
immediately switches to the priority channel.  
Note: The scanner does not check trunked channels, priority channels if the channel is  
locked out, or in locked-out banks.  
By default, the first channel of each bank is set as priority. To change the priority channel,  
manually select the channel you want to set as the priority channel. Then hold down PRI  
for about 2 seconds. The scanner beeps twice and the new priority assignment is made.  
40  
 
Programming Trunked Systems  
Before you start programming your scanner to track a trunked system, consider the following:  
Programming Trunked Systems  
You might want to gather all information about the systems you want to monitor before  
you start to program the scanner. The “Motorola Trunking Worksheet”, “LTR Trunking  
Worksheet”, and “EDACS Trunking Worksheet” included in the help file included with  
the demo software (download at http://www.uniden.com) make this easy.  
You can program only one trunked system per bank. For example, if you are  
programming Bank D, you can only select channels 151-200 with the rotary tuner or  
using the HOLD U or LIMIT V keys.  
Note: To clear a mistake while entering a frequency, press . twice then enter the frequency  
again.  
Setting the Scanner to Trunking Programming Mode  
You must set the scanner to its trunking programming mode before you can program  
channels and enter trunking frequencies.  
If you are in conventional scan mode:  
1. Hold down TRUNK. The scanner beeps twice and BANK and TRUNK flash.  
2. Select the trunking bank you want to program.  
If you are in trunking scan mode:  
1. Press TRUNK to return to conventional mode if you have been monitoring a trunking bank.  
2. Hold down TRUNK. The scanner beeps twice and BANK and TRUNK flash.  
3. Select the trunking bank you want to program.  
Note: When you set the scanner to its trunking programming mode, you cannot select  
channels in other banks.  
Programming Motorola Systems  
Programming Channels and Entering Trunking Frequencies  
1. Hold down TRUNK for about 2 seconds. The scanner beeps and BANK, TRUNK, and  
the bank letters A-J blink.  
2. Press a bank key to select the bank where you want to store the frequencies.  
3. Select Motorola scanning by turning the rotary tuner or repeatedly pressing HOLD U  
or LIMIT V to select one of the following Motorola scanning choices:  
E2-800 (Motorola Type II 800 MHz)  
E2-900 (Motorola Type II 900 MHz)  
E2-HI (Motorola Type II VHF)  
E2-UHF (Motorola Type II UHF)  
E1 (Motorola Type I)  
Then press E on the keypad.  
41  
 
   
4. If necessary, repeatedly press HOLD U or LIMIT V until PRO9 F appears. Then press  
E on the keypad.  
5. To enter trunking frequencies, use the keypad to enter the first frequency, then press E  
on the keypad. (Press . to enter the decimal point).  
Note: To clear a mistake while entering a frequency, press . twice then enter the  
frequency again.  
6. For each additional frequency, select the next channel by turning the rotary tuner or  
pressing HOLD U. Then use the keypad to enter the next frequency, then press E on  
the keypad. (Press . to enter the decimal point).  
7. If you selected E2-800, E2-900, or E1 in Step 3, stop here.  
Otherwise, if you selected E2-HI or E2-UHF in Step 3, follow these steps to enter the  
band plan (base frequency, spacing frequency, and offset channel) for the system you  
want to scan.  
a. Press DATA.  
b. Turn the rotary tuner or repeatedly press HOLD U or LIMIT V until BASE appears.  
Then press E.  
c. Select the band plan by pressing A, B, or C.  
d. Use the keypad to enter the base frequency, then press E and press HOLD U.  
e. Use the keypad to enter the step frequency, then press E and press HOLD U.  
f. Use the keypad to enter the channel offset, then press E and press HOLD U.  
g. If the system uses more than one band plan, press DATA then repeat Steps c-f.  
Programming Fleet Maps  
If you programmed a trunk tracking bank and press SRC, talk group ID’s appear. Since  
your scanner defaults to monitor Type II systems, most if not all ID’s appear as even  
numbers. However, if you notice an even mix of odd and even talk group ID’s, for example  
6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or  
Hybrid system.  
You might also notice that you are missing responses when you hold on an active ID.  
Unlike Type II systems, Type I/IIi systems require a fleet map that sets specific fleet-  
subfleet parameters. It’s easy to select a fleet map for your scanner; what isn’t always  
easy is selecting or programming a map that matches your particular area.  
There are 16 preset fleet maps listed in the appendix that you can choose, and these are  
usually a good place to start when setting up a Type I/IIi trunk tracking bank. If you choose  
a preset map and still have difficulty following complete conversations, then you’ll have to  
program your own fleet map.  
42  
 
Selecting a Preset Fleet Map  
1. If you are still in the programming mode, press DATA. Otherwise, select the trunking  
programming mode and bank you want to change. Then, repeatedly press HOLD U or  
LIMIT V until E1 appears, then press E.  
2. Repeatedly press HOLD U or LIMIT V until FLEET appears, then press E.  
3. Repeatedly press HOLD U or LIMIT V to select the fleet map you want. For example,  
E1P2.  
4. Press E then press SRC.  
The scanner exits the trunking programming mode, acquires the data channel, and begins  
searching using the preset fleet map you chose.  
Note: You will now begin to see Type I Fleet-Subfleet ID’s. For example, 100-12,100-9,  
000-12, 400-8, etc. See “User Defined Fleet Maps” on Page 55 for more information about  
Type I ID’s.  
How do you know if the preset map is correct? You’ll have to listen to see if you are  
following complete conversations. If not, try another preset fleet map.  
Programming a Custom Fleet Map  
You might want to read “User Defined Fleet Maps” in the Appendix and use the “Motorola  
Trunking Worksheet” included in the help file included with the free demo software  
(download at http://www.uniden.com) before programming a custom fleet map. “User  
Defined Fleet Maps” includes a detailed explanation of scanner fleet map programming, as  
well as a table listing the fleet map size codes.  
1. If you are still in the programming mode, press DATA. Otherwise, select the trunking  
programming mode and bank you want to change.  
2. Repeatedly press HOLD U or LIMIT V until E1 appears.  
3. Press E.  
4. Repeatedly press HOLD U or LIMIT V until FLEET appears, then press E.  
5. Repeatedly press HOLD U or LIMIT V to select USR.  
6. Press E.  
7. Enter the size code for the first block by repeatedly pressing HOLD U or LIMIT V until  
the correct size code appears.  
8. Press E. The next available block appears.  
9. Repeat Steps 7 and 8 until you have selected a size code for each block.  
For specifics about each size code, see “Size Code Restrictions” on Page 55.  
10. Press SRC.  
The scanner exits the trunking programming mode, acquires the data channel, and begins  
searching using the map you’ve programmed.  
43  
 
Programming Talk Group ID’s  
Enter the talk group ID for each group you entered:  
1. If you are still in the programming mode, press DATA. Otherwise, hold TRUNK for 2  
seconds, then select the bank and system type and press E.  
2. Repeatedly press HOLD U or LIMIT V until PRO9 ID appears. Then press E.  
3. Repeatedly press HOLD U or LIMIT V or rotate the dial to select the talkgroup ID  
channel you want to program.  
4. Enter an ID. To enter the dash used in Type I ID’s, use the . key.  
5. Repeat Steps 3 and 4 for all ID’s you want to program.  
Programming a Hybrid System  
A hybrid system is simply a Type I system with some blocks designated as Type II blocks.  
To program a Hybrid system, follow the steps listed in “Programming Motorola Systems”  
on Page 41. However, if you want a block to be Type II, select Size Code S-0.  
When you begin searching a trunking bank with a hybrid fleet map, you will see both types  
of system ID’s. That is, Type II ID’s usually appear as an even number without a dash;  
Type I ID’s appear as a three or four digit number, followed by a hyphen, followed by a one  
or two digit number.  
Programming EDACS Systems  
1. Hold down TRUNK for about 2 seconds. The scanner beeps and BANK, TRUNK, and  
the bank letters A-J blink.  
2. Press a bank key to select the bank where you want to store the frequencies.  
3. Select EDACS scanning by turning the rotary tuner or repeatedly pressing HOLD U or  
LIMIT V to select one of the following EDACS scanning choices:  
ED-HI (Wideband, 9600 bps)  
ED-LO (Narrowband, 4800 bps)  
ED-SCT (SCAT)  
Then press E on the keypad.  
4. If necessary, repeatedly press HOLD U or LIMIT V until PRO9 F appears. Then press  
E on the keypad.  
5. To enter the trunking frequencies for LCN1, use the keypad to enter the first frequency,  
then press E on the keypad. (Press . to enter the decimal point).  
Note: To clear a mistake while entering a frequency, press . twice then enter the  
frequency again.  
6. For each additional frequency, select the next channel by turning the rotary tuner or  
pressing HOLD U. Then use the keypad to enter the next frequency, then press E on  
the keypad. (Press . to enter the decimal point).  
44  
 
 
7. If you selected ED-SCT in Step 3, stop here.  
Otherwise, if you selected ED-HI or ED-LO in Step 3, follow these steps to enter the  
talk group ID (agency, fleet, and subfleet) for the system you want to scan.  
a. Press DATA.

Care and Maintenance  
GCeanerreal Uasne d Maintenance  
• Turn the scanner off before disconnecting the power.  
• Always write down the programmed frequencies in the event of memory loss.  
• If memory is lost, simply reprogram each channel. The display shows 000.0000 in all  
channels when there has been a memory loss.  
• Always press each button firmly until you hear the entry tone for that key entry.  
Location  
• Do not use the scanner in high-moisture environments such as the kitchen or bath-  
room.  
• Avoid placing the unit in direct sunlight or near heating elements or vents.  
• If the scanner receives strong interference or electrical noise, move it or its antenna  
away from the source of the noise. If possible, a higher elevation might provide better  
reception.  
• Also try changing the height or angle of the antenna.  
Cleaning  
• Disconnect the power to the unit before cleaning.  
• Clean the outside of the scanner with a mild detergent.  
To prevent scratches, do not use abrasive cleaners or solvents. Be careful not to rub  
the LCD window.  
• Do not use excessive amounts of water.  
Repairs  
Do not attempt any repair. The scanner contains no user serviceable parts. Contact the  
Uniden Customer Service Center or take it to a qualified repair technician.  
Birdies  
All radios can receive “birdies” (undesired signals). If your scanner stops during Scan  
mode and no sound is heard, it might be receiving a birdie. Birdies are internally generated  
signals inherent in the electronics of the receiver.  
Press L/O to lock out the channel, then press SCAN to resume scanning.

User Defined Fleet Maps  
Type I Programming Information  
When a Type I system is designed, the address information for all the ID’s is divided into 8  
equal sized blocks, numbered 0–7. When you program your scanner to track a Type I  
system, you must select a size code for each of these blocks. When you have assigned a  
size code to all 8 blocks, you’ll have defined the fleet map for the system you are tracking.  
Each size code determines the number of fleets, subfleets, and ID’s each block will have.  
For example, a size code of S-4 has one fleet, which is divided into 16 separate subfleets,  
and it has a total of 512 individual ID’s.  
When a block is assigned a size code, the fleet or fleets created within the block are  
assigned a Type I ID. The way these ID’s display on your scanner depend on the block  
number and the block’s size code. When a Type I ID appears, the leftmost digit represents  
the block which contains the ID.  
The next two digits identify which fleet is active, and the last digit(s) identifies the subfleet.  
The details concerning how the size codes are selected by a Type I System designer are  
highly dependent on the specific needs of the system’s users. Some organizations might  
want many subfleets with only a few radios each, while another organization might want  
only a few subfleets with many radios each. Your task is to program your fleet map with the  
same size code assignments as the trunked system. If you do this accurately, you’ll track  
all the Fleet-Subfleet combinations used by the system. In other words, you’ll hear  
complete communications while monitoring a trunked system.  
If you don’t already know the size codes used, you’ll have to guess at them. But since you  
don’t have to figure out all the blocks at once, this isn’t as hard as it seems. Select a size  
code for a block, and then press SCAN. Now listen to the communications. If you decide  
you are receiving most of the replies to the conversations with ID’s assigned to the block  
you just programmed, then you’ve probably selected the right size code and can work on  
the next block of the map.  
Finally, for most public safety systems there are some size codes which are more  
common. S-3 and S-4 are probably the most common, followed by S-10, S-11, and S-12.  
Size Code Restrictions  
If you select size code S-12, S-13, or S-14, there are some restrictions as to which blocks  
can be used for these codes.  
S-12 can only be assigned to Blocks 0, 2, 4, or 6.  
S-13 can only be assigned to Blocks 0 and 4.  
S-14 can only be assigned to Block 0.  
55  
 
   
Since these size codes require multiple blocks, you will be prompted for the next available  
block when programming a fleet map. For example, if you assign Block 0 as an S-12, you  
will be prompted for b2, the next block available, instead of b1. And if you assign Block 0  
as an S-14, you would not see another prompt because it uses all available blocks.
