How caller ID works
If you subscribe to caller ID service provided by
your telephone service provider, information about
each caller is displayed between the first and
second ring.
Caller ID overview
The time and date of the call, the caller’s name
and telephone number are included on the screen
if they were sent by the caller’s telephone service
provider. Due to regional service differences, the
caller ID information might not be available for
every incoming call. In addition, the callers might
intentionally block their names and/or telephone
numbers. Other messages might appear on the
screen. Refer to Caller ID special messages on
page 34 for more information.
Caller ID information appears on the screen as
long as the telephone rings, for 15 seconds after
the caller hangs up, or after the call is answered
at another telephone on the same line.
If you subscribe to caller ID service, the time and
date are set automatically with each incoming call.
You can also set the time and date yourself (see
Set date and time on page 17).
NOTE: If you select COMBINED in REPEATED
CALLS (see Feature summary on page 15) and
a caller has called more than once, the REP icon
appears with the caller ID entry.
