How caller ID works

If you subscribe to caller ID service provided by your telephone service provider, information about each caller will start to be displayed between the first and second

ring.	Time of call	Date of call
Caller’s	12:08 PM 12/26
	SMITH, JOHN
name	5550123	L1

Caller's telephone number

The time and date of the call, the caller’s name and telephone number are included on the screen if sent by the caller’s telephone service provider. The incoming line of the call also appears on screen (L2 in the above example). If two calls come in at the same time, the screen displays information about both calls:

Caller's name	SMITH, JOHN
on Line 1	5550123	L1
Caller's name	BROWN, MARY	Line of call
on Line 2	5550127	L2

In certain circumstances, there may be up to a 6-second delay before the screen displays both caller's information. Other messages may appear on screen. See Display screen messages on page 57 for more information. Caller ID information will remain on the screen for about 30 seconds after the telephone stops ringing or until the call is answered.

If you subscribe to caller ID service, this telephone automatically resets the time and date each time new call information is received. You can set the time and date yourself if desired. (See Set the time and date on page 22.)

NOTES:

1.Caller ID features work only if both you and the caller are in areas offering caller ID service, and if both telephone companies use compatible equipment.

2.If caller ID information is received while you are programming the memory, the call information will be stored in call history without appearing on screen.
