Problem Suggestion
The system does
not receive caller ID,
or the system does
not display caller ID
during call waiting.
Make sure you subscribe to caller ID with call waiting features provided by the local telephone
company.
The caller may not be calling from an area which supports caller ID.
Both you and the caller’s telephone companies must use equipment which are compatible
with caller ID service.
If you subscribe to high-speed Internet service (Digital Subscriber Line - DSL) through your
telephone lines, you must install a DSL lter between the telephone base and the telephone
wall jack. The lter will prevent noise and caller ID problems caused by DSL interference.
Please contact your DSL service provider for more information about DSL lters.

Caller ID entries do not
match the numbers I
need to dial.
Although the call log entries you receive have 10 digits, (the area code plus the seven-digit
number,) in some areas, you may need to dial only seven digits, or a 1 plus the seven digits,
or a 1 plus the area code plus the seven digits. You can change the number of digits that you
dial or store from the call log.
While reviewing the call log, press # repeatedly to display these dialing options for local and
long distance numbers before dialing or saving the telephone number.

The answering system
does not answer after
the number of rings to
which I programmed it.
Make sure the answering system is on. When the answering system is on, the red light on the
ANS ON/OFF key should be lit.
If toll saver is activated, the number of rings changes to two when there are new messages
waiting (see page 33).
If the memory is full or if the answering system is off, the system will answer after ten rings.
In some cases, the answering system will be affected by the ringing system used by the local
telephone company.
