Caller ID Operation

Chain Dialing Service Numbers

For quick recall of numbers for special ser- vices (such as alternate long distance or bank by phone), store each group of num- bers in its own memory location.

When calling special services, dial the ser- vice’s main number first. Then, at the appro- priate place in the call, press MEM, then the number for the location where the additional numbers are stored.

Testing Stored Emergency Numbers

If you store an emergency service’s number (police department, fire department, ambu- lance) and you want to test the stored num- ber, make the test call during the late evening or early morning to avoid peak de- mand periods. Remain on the line to explain the reason for your call.

Message Waiting

If you subscribe to a message waiting ser- vice with your local telephone company, the

CHARGE/IN USE/MESSAGE indicator flash- es and C;II7=;ý M7?J?D= appears for about six seconds when you have a new message waiting. The indicator continues to flash until you listen to all of your messages.

If you subscribe to Caller ID service from your phone company, the system automati- cally displays information about calls you re- ceive and stores the information in Caller ID memory. The system can store up to 40 number records (the most recent is 40), then replaces the oldest call with each new one.

The first line of the Caller ID record shows the calling time, date and the number of calls. The second line shows the caller’s phone number. The third line shows the call-

er’s name, if available (See “Caller ID Mes- sages”).

Note: The CHARGE/IN USE/MESSAGE in- dicator flashes during an incoming call, and NEW CALL # appears. The latest Caller ID record appears when the phone rings, then NEW CALLS # or REPT remains on the dis- play after the last incoming call.

Call Waiting

If you subscribe to Call Waiting and a call comes in while you are on the phone, you hear a tone that indicates you have another call. The system displays the Caller ID/Call Waiting information for about 10 seconds, then stores the information.

To answer the incoming call, press FLASH/ DELETE. To resume the previous phone con- servation, press FLASH/DELETE again.
