My caller ID features
are not working
properly
Caller ID is a subscription service. You must
subscribe to this service from your telephone service
provider for this feature to work on your telephone.
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.
Make sure the area codes are set correctly in the
telephone (see Set home area code and Set local
area code on page 19).
Reset the telephone (see Common cure for
electronic equipment on page 59).
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.
