System Operation  
8W-1KU Receiver  
Once the receiver is connected to the power  
source, press the Power Button (1) for two  
seconds. The LCD Displays (8) will light  
(showing Group, Channel, RF Level Meter,  
and Output Volume). The Diversity A/B (2) and  
the AF PEAK LED (3) are off at this time and  
will display when the transmitter is on and  
the audio is transmitted. To turn off, press the  
Power button for two seconds. The LCD will  
display “OFF” then the backlight will turn off  
indicating the receivers are off.  
Installing antennas  
Install antennas on back by connecting the  
two antennas (21) included with your system  
onto the two RF Connectors (14/19) located on  
the back of the 8W-1KU receivers. The two  
antennas must be installed in order for the  
diversity circuit to work properly. The optimal  
positions of the antennas are 45° from  
the receiver and 90° from each other. For  
maximum range, it is always best to maintain  
a line-of-sight (no obstructions) between the  
receiver antennas and the transmitter at all  
times whenever possible.  
Connect either the ¼” Unbalanced Audio Out  
(17) or each XLR Balanced Mic Outs (15) to  
your mixing board, effect, or amplifier inputs  
(See Connecting the Audio Outputs section).  
For front antenna installation, first install  
optional FaMK-2 antenna extension Cables (13a),  
insert one end of each BNC cables into a  
rack ear hole and secure using the removable  
nuts. Lock other end of the BNC cables to an  
RF Connector (14/19) on the back of the unit.  
Then connect the two antennas to the front  
of the receiver.  
Button Function on the Receiver  
The Power Button (1) is used to turn ON or  
OFF all receivers at the same time. When this  
power button is pressed for two seconds, the  
blue backlights on the lCD Displays (8) will light  
up indicating the receivers are on. Press the  
Power button again for two seconds to turn  
off the receivers. The backlight on the LCD  
will display “OFF” indicating the receivers are  
off. At power-off the 8W-1KU receivers will  
store the last settings entered and re-display  
them at power-on. It can be reprogrammed  
to any new Group/Channel, or Volume level.  
The default factory setting is Group 01  
(Receiver 1) and 02 (Receiver 2), 03 (Receiver  
3) and 04 (Receiver 4), Group 05 (Receiver 5)  
and 06 (Receiver 6), 07 (Receiver 7) and 08  
(Receiver 8), Channel 00 and Volume 63 for all  
receivers.  
Rack-mounting the Receiver  
The Nady 8W-1KU receiver wireless system  
has built-In Rack ears (13). Simply attach the  
rackears with supplied screws on both sides  
and install the receiver onto the rack.  
Note: Do not mount the receiver on a rack directly  
above an amplifier or other source of high heat.  
This could degrade the performance of the  
8W-1KU. Always ensure adequate airflow and heat  
dissipation in any rack configuration.  
The (Up) or (Down) Buttons (7) are active  
while in the Set mode, or can be used to  
change Volume Level (11) at anytime.  
Powering the Receiver  
To power the receivers, plug the provided AC/  
DC Power Supply (20) adapter into the DC Input  
Jack (18) on the back of the receivers, then  
plug the adapter into an AC outlet.  
When the Set Button (6) is repeatedly pressed  
the lCD Display (8) menus will cycle in the  
following order:

first receiver. Repeat these procedures for the  
remaining receivers to be used with the system.  
During manual programming, the selected  
function will flash for five seconds or press  
the Set button to confirm the selection and  
the display will return to the main menu.  
If you are not satisfied with a channel after  
scanning, repeat anytime for locating another free  
channel.  
The aUTO-SCan / aSC (IR Sync) Button (2)  
has two functions:  
Long press (hold ~2 seconds) for AUTO-  
SCAN for finding a clear channel within  
the frequency band (with all TXs turned off  
at this time). Clockwise running segments  
on the LCD display show the scanning  
is in progress which normally takes ten  
seconds. When it finds an interference-  
free channel, it will display and store that  
channel for use. Then ASC IR Sync the TX  
as described below.  
Selecting the 8W-1KU Receiver  
Volume level / Group / Channel  
This section will also aid in finding desired  
channel(s) of operation when setting up  
your system(s).  
Press the Set Button (6) 3 times to check  
the current Volume levels (12) setting. To  
change the Volume Levels, press the  
(Up) or (Down) Buttons (7) anytime for  
single stepping, or hold the Up/Down button  
continuously for faster level selection.

one more time. Selecting 0 should mute the  
receiver and no output for the Line Out only.  
The XLR out is unaffected.  
Short press (hold ~ 1 second) to transfer  
the selected frequency information from  
the receiver to the transmitter for easy  
synchronization prior the transmitter can  
be used. When short pressing the ASC  
IR Sync button while the main menu is  
displayed, the IR LED (4) will light up red  
and stay for about five seconds. This  
indicates IR transmission is in progress  
and IR data is transferring during this  
period. A transmitter should be used  
at this time to receive data from the  
receiver (see IR Sync Programming in  
Programming sections of HT-1KU and  
BT-1KU transmitter sections). Upon  
successful data transferred (usually in  
about three seconds) the IR LED stops  
and the transmitter’s backlight will light  
up and the transmitter will transmit a  
radio signal on the same channel as the  
receiver. The Signal Strength and Diversity  
Indicators on the receiver’s display will  
then light up, indicating that the IR link is  
completed. If manual channel selection is  
preferred, skip this selection.  
Choose the 8W-1KU operating frequency  
by selecting one of 10 Groups (9) and one  
of 100 Channels (10) that are determined to  
be desirable open channels. Press the Set  
button to enter the Group setup mode and

Connecting the audio Outputs  
8W-1KU receiver has one Unbalanced audio  
Out (17) (adjustable Line level) SUM audio  
output and eight Balanced Mic Out (15) (fixed  
level) XLR jacks and each output works  
independently per receiver. The Unbalanced  
Audio Out is controlled by (Up) or  
adjusting the Squelch  
In normal operation, each 8W-1KU receiver’s  
Mute Control (16) works independently and  
should be adjusted clockwise (CW) to the  
minimum RF squelch setting at which  
the RF level Meter (12) and one of the LED  
Diversity a/B Indicators (2) will remain on  
while your transmitter is in normal use, up  
to the maximum operating range anticipated  
in use for your application. However, in  
areas of high RF activity, the MUTE control  
may need to be adjusted counterclockwise  
(CCW). If the transmitter is off, the receiver  
signal and the RF Signal Meter (12) and one  
of the LED Diversity a/B Indicators (2) is  
flickering or stay on continuously, the MUTE  
level should be adjusted higher level CCW  
(counterclockwise for less mute sensitivity  
level) to stop the flickering. Be careful not  
to adjust too high CCW setting as this may  
reduce the operating range to below what  
is needed. A range walk test will help in  
selecting the proper level. If the range is  
not critical, note that a counterclockwise  
(maximum mute) setting will also yield  
a quieter mute function, which might be  
desired in certain applications. The MUTE  
level is factory preset at clockwise (CW) for  
maximum sensitivity and operating range  
(i.e. clockwise (CW) for minimum squelch  
level—maximum usable range).  
(Down) Buttons (7) for volume control and  
the receiver Sum Volume Meter (11) will  
indicate the level selected. For unbalanced  
output, plug a ¼” mono (Tip/Sleeve) audio  
cable into the Unbalanced audio Out (17)  
and plug the other end into your mixing  
board or amplifier. When using the BT-1KU  
instrument transmitter system, connect  
the Unbalanced Audio Out directly to your  
instrument amp or preamp. At maximum  
receiver volume setting, as indicated by  
the Sum Volume Level display, the system  
output is approximately +4dB higher than  
a direct cord-to-amp connection. Note that  
all receivers output will be mixed together  
as per the individual receivers’ volume  
settings as selected by the up/down volume  
controls. If separate signals are required for  
each instrument then the Balanced Mic Out  
sockets must be used. However, they are  
not line level or adjustable. The SUM out is  
best utilized for switching between separate  
transmitters during performance with  
only one audio signal at a time fed to the  
instrument amplifier. For balanced output,  
plug an audio cable with an XLR connector  
into each receiver and plug the other end  
into your mixing board or amplifier inputs  
accordingly.  
audio level and Peak leD Indicator  
The 8W-1KU receiver has an aF Peak leD (3)  
display for each receiver and each works  
independently per channel. The AF Peak  
LED occasional flickering green on normal  
or loud inputs to the transmitter is normal. If  
the AF Peak LED lights green continuously,  
Note: As when making any connection, make sure  
the amplifier or mixing board volume is at the  
minimum level before plugging in the receiver to  
avoid possible sound system damage.

Your 8W-1KU receiver is now operational  
and ready to use. Once you have completed  
the above steps, proceed to the following  
instructions for the HT-1KU Handheld or BT-  
1KU Instrument transmitter.  
Note: Only one transmitter can be used with one  
receiver. It is not possible to use two transmitters  
on the same frequency and mix the output of  
these transmitters into one wireless receiver.  
However, as this is an eight receiver unit, eight  
transmitters on separate frequencies can be  
utilized, one with each receiver.

Powering the Transmitter On/Off  
HT-1KU Handheld  
Microphone Transmitter  
To turn on the transmitter, slide the Power  
On/Off Switch (28) to the “ON” position.  
The LCD backlight will light up, indicating  
the unit is now on. After five seconds  
the backlight will automatically turn off to  
conserve battery life. The Group (30), Channel  
(31), Input Volume level (32), and Battery  
Meter (33) indicator icons stay on for normal  
operation.  
Setting up the Transmitter  
The HT-1KU requires two AA size batteries  
to operate. To install the batteries onto  
the battery compartment, unscrew the  
Battery Compartment Cover (22) by turning  
counterclockwise until loose and slide down  
the cover, exposing the Battery Compartment  
(35). Insert two fresh aa batteries (36)  
according to the correct polarity as indicated  
on the transmitter body. Screw the battery  
cover back onto the microphone, making  
sure it is securely tightened. Fresh alkaline  
batteries can provide up to 8-10 hours of  
operation, but in order to ensure optimal  
performance it is recommended that the  
batteries be replaced after 6-8 hours of  
use or as indicated to be necessary by the  
flashing “BATT” Battery Meter Icon (33).  
As many of the LCD battery meter levels  
should stay lit as possible as they indicate  
usable battery strength. As the batteries  
weaken, fewer of the level indicators will  
stay lit until only one bar shows, which will  
then flash to warn that the batteries are now  
too low and should be replaced as soon as  
possible with fresh ones.  
To preserve battery life, turn the transmitter  
off when not in use. To turn the transmitter  
off, slide the power on/off switch to the  
“OFF” position. The LCD will display “OFF,”  
no LCD or backlight is lit up and the unit will  
be off.

Use the wireless IR leD Receptor Sensor (34)  
to download pre-programmed channels  
from the receiver. Start programming by  
holding the IR Receptor Sensor/Window  
about 6” in front the receiver to be used.  
On the receiver, when short pressing the  
aSC IR Sync Button (5), while the main menu  
is displayed, the IR Infrared leD (4) will light  
up red and stay for about five seconds. This  
indicates IR transmission is in progress and  
IR data is transferring during this period.  
Upon successful data transfer (usually in  
about three seconds) the IR LED stops and  
the transmitter’s backlight will light up and  
the transmitter will transmit a radio signal  
on the same channel as the receiver. The  
Signal Strength and Diversity Indicators on  
the receiver’s LCD display will then light  
up, indicating that the IR link is completed.  
Note, if procedure is not done correctly  
during the three seconds of active data  
transfer, the receiver and the transmitter  
do not link and transmitter’s previous  
programmed channel remains unchanged.  
To change the volume input level only,  
press the Set button three times to select  
the volume input level setting. Use the Up/  
Down button to change in four steps from  
0dB to -30dB (for loudest input). The level  
is preset at -10dB for the HT-1KU, which is  
best for most applications.  
For normal operation, the transmitter should  
have the same Group/Channel as displayed  
on the receiver. The default factory setting  
is Group 01 (Receiver 1) and 02 (Receiver  
2), 03 (Receiver 3) and 04 (Receiver 4),  
Group 05 (Receiver 5) and 06 (Receiver 6),  
07 (Receiver 7) and 08 (Receiver 8) for all  
receivers.  
After programming is finished, slide the  
battery cover back then turn the Mic Ball (23)  
counterclockwise to secure the housing.  
The HT-1KU is now ready for use.  
Note: The IR link is infrared light and thus works  
best when this data transfer is accomplished in a  
light-shielded or darker environment. It may not  
be successful in a brightly lit area. If the transfer  
fails, repeat the procedure in a darker location  
or somehow shield the link from outside light to

the connection to the cable by lining up  
the slot of the 3.5mm mini connector and  
turning the ring to securely lock in.  
BT-1KU Bodypack Transmitter  
(lT, lT/HM or GT)  
Setting up the Transmitter  
The BT-1KU bodypack requires two aa  
Batteries (50) to operate. To install the  
batteries into the battery compartment, lift  
the Battery Compartment Door (46) by grabbing  
the two spring-loaded locking tabs and pull  
out, exposing the Battery Compartment (45).  
Insert two fresh AA batteries according  
to the correct polarity as indicated on the  
transmitter body. Close the battery cover,  
ensuring the cover is snapped shut. Fresh  
alkaline batteries can last provide up to 8-10  
hours of operation, but in order to ensure  
optimum performance it is recommended  
that the batteries be replaced after 6-8 hours  
of use or as indicated necessary by the  
Powering the Transmitter On/Off  
To turn on the transmitter, slide the  
Power Off/Mute/On Switch (38) to the “MUTE”  
(middle) position (transmitter on, audio  
muted). The LCD backlight will light up.  
The unit is now on. After ten seconds the  
backlight will automatically turn off. The  
Group (30), Channel (31), Input Volume level (32)  
and Battery Meter (33) remain on in normal  
operation.  
As many of the five LCD battery levels  
14  
 
should stay lit as possible, indicating usable  
battery strength. As the batteries weaken,  
fewer of the level indicators stay lit until  
only one bar shows, which will then flash to  
warn that the batteries are now too low and  
should be replaced as soon as possible. To  
preserve battery life, turn the transmitter off  
when not in use. To turn the transmitter off,  
slide the Off/Mute/On switch to “MUTE”  
and then “OFF”. The LCD will display  
“OFF”, no LCD or backlight is lit up and the  
unit will be off.  
a radio signal on the same channel as the  
receiver. The Signal Strength and Diversity  
Indicators on the receiver’s LCD display will  
then light up, indicating that the IR link is  
completed.  
Note: If procedure is not done correctly during the  
three seconds of active data transfer, the receiver  
and the transmitter do not link and transmitter’s  
previous programmed channel remains  
unchanged.  
The IR link is infrared light and thus works best  
when this data transfer is accomplished in a  
light-shielded or darker environment. It may not  
be successful in a brightly lit area. If the transfer  
fails, repeat the procedure in a darker location  
or somehow shield the link from outside light to  
success-fully program the transmitter with the  
pre-programmed group and channel info from the  
receiver.  
At Power Off the transmitter will store  
the last settings entered and re-display  
them at the next power on where it can be  
reprogrammed to any new Group/Channel  
or Volume level at the first time of use or  
anytime later. The factory default setting  
for Volume 0dB is same for all transmitters.  
These settings are optimal for most  
applications.  
Manual Programming (GRP/CH and Volume):  
The transmitter’s frequency is set using the  
Set Button (42) and then the (Up) or (Down)  
Buttons (41). During manual programming,  
the selected function will flash for five  
seconds, or press the Set button to confirm  
the selection and the display will return  
to the main menu. To start, press the Set  
button once. The backlight on the lCD (40)  
will light up and the Group (30) icon will flash.  
Use the Up/Down buttons to change the  
group. When a group selection is finished,  
press the Set button again for the channel  
selection. The Channel Icon (31) will now  
flash. Again, use the Up/Down buttons to  
change the channel as desired. When the  
group/channel selection is done, press the  
Set button again to enter volume level input  
setting and then press Up/Down button to  
change in four steps from 00dB to -30dB  
(for loudest input) or press the Set button a  
second time to exit to the main menu.  
Programming the BT-1KU  
to the Selected Channel  
The transmitter can be programmed to the  
same frequency as selected for the receiver,  
either via automatic synchronization using  
the IR Sync function or manually on the  
transmitter itself.  
IR Sync Programming:  
Use the wireless IR leD Receptor Sensor (43)  
to download pre-programmed channels from  
the receiver. Start programming by holding  
the IR LED Receptor about 6”-12” from  
the receiver’s IR leD Window (4), then press  
the IR Sync Button (5) on the receiver to be  
used. When short pressing the ASC IR Sync  
Button, while the main menu is displayed,  
the IR LED will light up red for about five  
seconds. This indicates IR transmission is in  
progress and IR data is transferring during  
this period. Upon successful data transfer  
(usually in about three seconds) the IR LED  
stops and the transmitter’s backlight will  
light up and the transmitter will transmit  
To change volume input level only, press the  
Set button three times to select the volume  
input level setting. Use the Up/Down to  
change in four steps from 0dB to -30dB  
(-30dB for loudest input). The level is preset  
15  
 
at -10dB for LT/HM and 0dB for GT. These  
settings are optimal for most applications.  
With Power Off/Mute/On switch in either  
in “MUTE” or ON” position the receiver’s  
RF Signal Meter (12) and one Diversity a or B  
(3) indicator should now be on, indicating a  
received signal from the transmitter. When  
ready to transmit audio, slide the power  
switch to “ON” position to un-mute. To  
mute, slide the power switch to “MUTE”  
again. Adjust the volume of the receiver per  
Connecting Audio Outputs section above.  
For normal operation, the transmitter should  
have the same Group/Channel as displayed  
on the receiver. The default factory setting  
is Group 01 (Receiver 1) and 02 (Receiver  
2), 03 (Receiver 3) and 04 (Receiver 4),  
Group 05 (Receiver 5) and 06 (Receiver 6),  
07 (Receiver 7) and 08 (Receiver 8) for all  
receivers. After programming is finished,  
close the battery compartment door,  
ensuring that it latches. The BT-1KU is now  
ready for use.  
Note: Avoid acoustic feedback (howling or  
screeching) by taking care in selecting PA volume,  
transmitter location and speaker placement.  
The RF Signal meter and the Diversity A/B  
indicator on the receiver’s LCD display should be  
“On” in normal operation.  
Note: If you are using multiple transmitters at  
the same location, set up the first transmitter  
and leave it ON and keep it 3 ft. away from the  
receivers. Then start AUTO-SCAN on the second  
receiver. This avoids duplicate selection of the  
same channel as already selected for the first  
receiver.  
Instrument Use (BT-1KU/GT only)  
Secure the connection of the GT  
(instrument) cable by lining up the slot  
of the 3.5mm mini locking Input Jack (37)  
connector and turning the ring to securely  
lock in. When ready to play, slide the Power  
Off/Mute/On Switch (38) to “ON” position  
to un-mute the audio. Adjust the volume  
lower on the receiver’s Unbalanced audio  
Output (17) for one-to-one unity gain with a  
hardwired cord or select up to an added  
4-5dB boost by leaving the receiver volume  
to maximum for normal use with guitars  
and bass guitars. Note this function is best  
when using two transmitters for switching  
during performance as these is only a single  
mixed output from the two receivers. If an  
individual output per receiver is desired, use  
the XlR Mic Outputs (15), noting that those are  
only fixed Mic level outputs.  
If you are not satisfied with a channel after  
scanning, repeat again anytime for selecting  
another free channel.  
Operating the BT-1KU  
Bodypack Transmitter  
During normal operation with the unit  
powered on, the transmitter power level can  
be changed by sliding the RF Power Switch  
(44) to “H” to increase the transmitted  
RF power (for longer range) or to “L” to  
decrease the RF power (reduced range).  
This is a useful feature as the “L” setting  
increases battery life and also optimizes  
the number of channels that can be used  
simultaneously in a given location. Use  
this setting for normal use not requiring  
maximum operating range. A range walk  
test before use will determine which setting  
is best for your application.  
Note: The audio level should be adjusted on the  
instrument as when using a hard-wired cord.  
For most applications the transmitter’s Input  
Volume Level (32) should be set at 0dB for optimal  
performance. Use attenuation levels (-10dB,  
-20dB, -30dB) only for higher output instruments,  
such as bass guitars with active pickups, and then  
only if needed for cleaner sound.  
The Power Off/Mute/On Switch (38) has three  
positions and functions as a power on/off  
and an audio mute on/off switch. After the  
unit is powered on, slide the power switch  
to the “ON” position to un-mute the audio.

Consumer Alert  
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating  
this microphone system without a license is subject to certain restrictions: the system may not cause  
harmful interference; it must operate at a low power level (not in excess of 50mW); and it has no  
protection from interference received from any other device. Purchasers should also be aware that the  
FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.  
For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC)

Cautions and Troubleshooting  
See: Selecting the 8W-1KU Receiver Volume  
Level / Group / Channel  
Feedback  
Avoid acoustic feedback (howling or  
screeching) by taking care in selecting PA  
volume, transmitter location and speaker  
placement.  
Programming the HT-1KU/BT-1KU to the  
Selected Channel  
To reprogram, you must first find an open  
channel. To do this, follow the operating  
procedure outlined in Selecting the 8W-1KU  
Volume Level / Group / Channel. With the  
associated transmitter off, scroll through  
the groups/channels to find one that  
shows no received signal on the receiver’s  
RF Signal Meter (12) (no bars). Also, there  
must be no bars either on each of the  
three immediately adjacent channels both  
above and below the selected channel for  
optimum interference-free operation (i.e. in  
a field of seven adjacent channel total—  
with the channel used in the middle). If  
operating multiple 8W-1KU Series systems  
simultaneously, repeat this procedure  
with every new channel being selected,  
with previously tuned systems all on, both  
transmitters and receivers.  
Please also note the pickup pattern  
characteristics of the microphone selected.  
Unidirectional mics are more resistant to  
feedback. However, they pick up sound  
sources best that are directly in front of the  
mic. Also mics that are farther from the  
sound source require more acoustic gain  
and thus are also more prone to feed back  
than close-source mics such as handheld.  
no or low audio  
If you are not getting audio through the  
system, carefully re-check all setups.  
Especially note that the receiver and  
transmitter must be set to operate on the  
same RF channel. For BT-1KU bodypack  
transmitter, also confirm that the Power  
Off/Mute/On Switch (38) is not in the Mute  
position. The receiver’s Unbalanced line  
level Out (17) is adjustable so make sure the  
Volume (11) is set properly.  
Please note that wireless frequencies are  
shared with other radio services. According  
to FCC regulations, wireless microphone  
operations are unprotected from  
interference from other licensed operations  
in the band. If any interference is received  
by any Government or non-government  
operation, the wireless microphone must  
cease operation or change frequencies. The  
above statement is valid only for use in the  
U.S.A.  
RF Interference and Finding Open  
Channels  
If you encounter slight receiving  
interference when the transmitter is  
far from the receiver (from other than  
an operating TV station on the same  
frequency), often it can be overcome by  
adjusting the receiver‘s Squelch Control (16)  
(see Adjusting the Squelch). If receiving  
interference on a selected channel with  
the transmitter off, you must reprogram  
the receiver and transmitter to a different  
channel.  
Note: More bars in the Received Signal (12) icon  
indicate good signal strength in operation with the  
transmitter on, but more than 1 bar showing with  
the transmitter off also indicates the presence of  
likely RF interfering signals at that location. If this  
happens, select a different GRP/CH. One bar or  
less is ideal for interference-free operation.

Miscellaneous Tips  
For optimal operation with external  
antennas, low loss RF shielded cable  
should be used and the length of the  
cable should not exceed 10 ft. (3 m).  
Position the receiver so that it has the  
least possible obstructions between  
it and the transmitter. Line-of-sight is  
best!  
The receiver antennas should be  
During operation, the transmitter and  
the receiver should be as close as  
possible for optimum results but never  
closer than 3 ft. (1 m) as that may  
overload the receiver’s input circuitry  
and cause noises.  
kept away from any metal surfaces  
whenever possible as they can reflect  
away or shield the incoming RF signal.  
If the receiver’s volume control is set  
too high, it may overdrive the input  
of the attached audio mixer, causing  
distortion. Conversely, if the output  
is set too low, the overall signal-to-  
noise ratio of the system may be  
reduced, causing noticeable hiss. If  
such noise occurs, adjust the output  
level of the receiver so that highest  
sound pressure level going into  
the microphone transmitter causes  
no input overload in the mixer, but  
permits the mixer level control to  
operate in the normal range (not too  
high and not too low). This provides  
the optimum signal-to-noise for the  
entire system.  
For the best operation, the receiver  
should be placed at least 3 ft. (1 m)  
above the ground and 3 ft. (1 m) away  
from a wall or metal surface. The  
transmitter should also be at least 3 ft.  
(1 m) from the receiver. Keep antennas  
away from noise sources such as  
motors, automobiles, neon lights,  
signal processors, computers, as well  
as large metal objects.  
A receiver cannot receive signals  
from two or more transmitters  
simultaneously.  
Turn the transmitter off when it is  
not in use. For longest life, remove  
the batteries if the unit is not to  
be used for a long period as the  
transmitters draw a tiny residual  
current to maintain the programmed  
settings, even when turned off. Also,  
since batteries installed for a long  
time can sometimes corrode and/or  
leak, causing damage, it is generally  
recommended that batteries be  
removed whenever the transmitters  
are not being used.  
Before inserting the batteries, ensure  
that they are inserted with the correct  
polarity.  
Before operation, confirm that the  
receiver and associated transmitter are  
tuned to the same frequency group  
and channel number.  
After making a receiver channel  
change, ensure that the corresponding  
change is also made on the matching  
transmitter.  
Use only brand new alkaline batteries.  
Do not use “general purpose”  
carbon batteries. When batteries are  
weak, replace all the batteries at the  
same time. Do not mix new and old  
batteries.

When using the BT-1KU bodypack for  
instrument use: Scratchy noises can  
sometimes occur when an electric  
guitar with dirty pots or connections  
is used with a wireless system.  
Therefore, the supplied capacitor  
provides first-order filtering of the RF  
signal from the cord into the guitar and  
eliminates virtually all scratchy noises.  
Should your equipment still produce  
scratchy noise, we suggest these  
steps to eliminate problems:  
1) Make sure all guitar volume and tone  
pots are clean and all contacts are solid.  
This is very important.  
2) Solder a 47pF capacitor across the pot to  
ground terminal of the guitar’s volume and  
tone pots to provide extra filtering.
