Operation Manual

Appendix
The telephone does
not receive caller ID
or the telephone does
not display caller ID
during call waiting.
Make sure you subscribe to caller ID with call waiting
features provided by the telephone service provider.
The caller might not be calling from an area that
supports caller ID.
Both your and the caller’s telephone service providers
must use equipment compatible with caller ID service.
If you subscribe to high-speed Internet service (DSL
- digital subscriber line) through your telephone
line, you must install a DSL filter between the
telephone line cord and the telephone wall jack
(see Telephone installation on page 7). The filter
prevents noise and caller ID problems caused by
DSL interference. Please contact your DSL service
provider for more information about DSL filters.

The answering
system does not
answer after the
correct number of
rings.
Make sure the answering system is on (see To turn
on the answering system on page 44). When the
answering system is on, the /ANS ON/OFF light
should be lit.
If you choose tS 2-4 (or tS 4-6) in # OF RINGS,
the answering system picks up incoming calls after
two (or four) rings if there are any new messages.
When there are no new messages, the answering
system picks up incoming calls after four (or six)
rings. When you are retrieving messages from a long
distance call, it disconnects your call after three
(or five) rings to avoid long distance charges. (See
Feature summary on page 16.)
If the memory is full or if the answering system is
off, the system answers after 10 rings.
In some cases, the answering system may be
affected by the ringing system used by the
telephone service provider.
If you have voicemail provided by your telephone
service provider, you might have set your voicemail
to answer the call before the answering system
answers, see About the answering system and
voicemail on page 42 for details.
