the services are available, and you must subscribe to the services. Where Caller ID is  
offered, one or more of the following options are generally available:  
a)  
b)  
c)  
Caller’s number only  
Caller’s name only  
Caller’s name and number  
3) IMPORTANT NOTICE BEFORE INSTALLATION  
Each device that you connect to the phone line draws power from the phone line.  
This power draw is referred to as the device’s ringer equivalence number, or REN.  
The REN for the B250D is located on the bottom of the telephone.  
If you are using more than one phone or other devices on the same line, add up the  
value of all the RENs. If the total is greater than five (three in rural areas), your phone  
might not ring. If the ringer operation is impaired, the problem can often be rectified  
by removing a device from the line to reduce the total REN to the number allowed.

18) CALLER ID, CALL WAITING  
18.1 CALLER ID  
Caller ID is a service provided by your telephone company or service provider. When  
you subscribe to this service, the telephone company sends the incoming caller’s tele-  
phone number (and name, if available), and the call’s date and time, between the first  
and second rings. The CID display receives and displays this information for each  
call, and updates the display with the current date and time. The display also shows  
if the caller information is not available, or if the sender blocks that information.  
Your B250D will save up to ninety-nine (99) call records, after which it replaces the  
oldest call record with each new one.  
18.2 CALL WAITING  
If you are using the telephone when a new call comes in, and you subscribe to call  
waiting service from your telephone company, the display indicates that a new call  
is being received. To answer the incoming call, press the FLASH/LINK key. To resume  
the previous conversation, press the FLASH/LINK key again.

USING CALLER ID  
22) USING THE DIAL KEY  
You can quickly dial a Caller ID number by simply pressing the DIAL key.  
NOTE: You must store your home area code in order to use this feature. If you are calling a  
number that originated in your home area code, the Caller ID record will show only the seven digit  
number (without an area code.)  
Follow these steps to dial a number from a Caller ID record:  
1) Repeatedly press REVIEW or REVIEW to select the desired Caller ID  
record. If the displayed phone number matches your phone system’s  
dialing pattern, press DIAL twice to dial the number. If the phone number  
does not match your phone system’s dialing pattern, follow steps 2  
through 4 below.  
2)  
Press DIAL. The messages DIALING MENU and USE REVIEW KEY alternately flash  
on the display.  
3) Repeatedly press REVIEW or REVIEW to select the desired dialing patterns.  
4) Press DIAL. The phone number appears in the display. After the B250D  
dials the number, the message PICKUP PHONE appears in the display.  
NOTES: If the phone number’s area code matches the area code you have stored, the Caller ID  
provides you with four dialing pattern choices: an 8-digit number (1 plus the phone number);  
a 10-digit number (area code plus the phone number); an 11-digit number (1 plus the area code  
plus the phone number); a 7-digit number.  
If the phone number’s area code does not match the area code you stored, you can select whether  
or not to dial a ‘1’ before the phone number.  
If you have not yet stored an area code, the displays reads: SET AREA CODE 000, and the first ‘0’  
flashes.  
23) DELETING CALLER ID RECORDS  
The B250D allows you to delete individual Caller ID records, or all Caller ID records  
that have been reviewed. It will not allow the deletion of Caller ID records that have  
not been reviewed. You cannot delete Caller ID records during a call.  
To delete a single Caller ID record:  
1) Repeatedly press REVIEW or REVIEW to select a record, then press  
DELETE. The display will show the prompt DELETE?.  
2) Press the DELETE key once again. The name and number will be deleted  
from the phone book log. If there are no other records, NO CALLS will  
appear on display.  
To delete all Caller ID records:

key for approximately four seconds. ERASE ALL flashes twice in the display,  
then the phone beeps once to confirm that all records were deleted.  
24) PRIORITY (VIP) CALL  
This feature alerts you when an important (VIP) call is being received, from up to twenty  
(20) numbers of your choosing. When you receive a call from a number matching one  
stored in the VIP call record, the B250D sounds two quick beeps each time the phone  
rings, until you answer the call.  
NOTE:  
VIP call records are protected so you cannot delete them by mistake. To delete a  
VIP call record, you must first “unmark” it, using the steps in “Unmarking a VIP Call

25) MESSAGE WAITING  
If you subscribe to your telephone company’s message waiting service, the B250D  
tells you when you have a message waiting. The message waiting indicator icon will  
appear in the display, and remains until you retrieve the message. Depending on the  
type of message waiting service provided, the red message waiting light on the upper  
right corner of the top of the B250D will also blink. The indicator(s) will remain on  
until you retrieve the message(s.)  
NOTE: Refer to instructions provided by your service provider on how to retrieve messages.  
There are three types of message waiting:  
1)  
STUTTER DIAL TONE – if you subscribe to the telephone company’s message  
waiting service.  
2) FSK – if you subscribe to the telephone company’s CID message  
waiting service.  
3)  
MULTI-X – if you are behind a PBX system with message waiting service.  
For STUTTER DIAL TONE and FSK message waiting, set the message waiting switch at the  
bottom of the phone to FSK. For MULTI-X message waiting, set the message waiting  
switch to VMWI.  
26) TROUBLESHOOTING

CARE AND MAINTENANCE  
If you still experience problems, disconnect the phone. If other phones on the same  
line work properly, the fault may be with this particular phone, or have something to  
do with its installation. If you cannot determine the problem, take your telephone to  
your local dealer for assistance.  
27) CARE AND MAINTENANCE  
These suggestions will help you care for your phone so you can enjoy trouble-free  
service for many years:  
Keep the telephone dry. If it gets wet, wipe it dry immediately. Liquids might  
contain minerals that can corrode the electronic circuitry.  
Use and store the B250D only in normal temperature environments. Extreme  
temperatures can shorten the life of electronic components, and distort or melt  
plastic parts.  
Keep the telephone away from dust and dirt, which can cause premature  
wearing of parts.  
Handle the B250D gently and carefully. Dropping it can damage internal circuit  
boards and components, causing the phone to work improperly.  
Wipe the B250D with a damp cloth occasionally to remove dust and dirt.  
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the  
telephone.  
Modifying or tampering with internal components can cause a malfunction and  
might invalidate the warranty, as well as void your FCC authorization to operate  
the telephone. If your B250D is not performing as it should, see your dealer for  
assistance. If the trouble is affecting the telephone lines, the telephone company  
or service provider may ask you to disconnect your telephone until the problem  
is resolved.  
28) WHAT THE FCC WANTS YOU TO KNOW  
In the unlikely event that your B250D causes problems on the phone line, the tele-  
phone company can temporarily discontinue your service. If this happens, the tele-  
phone company attempts to notify you in advance. If advance notice is not practical,  
the telephone company notifies you as soon as possible and advises you of your right  
to file a complaint with the FCC. Also, the telephone company can make changes to  
its lines, equipment, operations, or procedures that could affect the operation of this  
telephone. The telephone company notifies you of these changes in advance, so you  
can take the necessary steps to prevent interruption of your phone service.  
29) LIGHTNING  
Your B250D has built-in protection circuits to reduce the risk of damage from surges  
in telephone line and power line current. These protection circuits meet or exceed  
FCC requirements. However, lightning striking the telephone or power lines can  
damage your phone. Lightning damage is not common. Nevertheless, if you live in  
an area that has severe electrical storms, we suggest that you unplug your phone  
during storms to reduce the possibility of damage.
