Troubleshooting
I experience poor sound quality when using the handset
speakerphone.
For increased sound quality while using the handset speakerphone, place
the handset on a flat surface with the dial pad facing up.
My caller ID isn't working.
•
Caller ID is a subscription service. You must subscribe to this service from
your telephone service provider for this feature to work on your phone.
•
The caller may not be calling from an area that supports caller ID.
•
Both your and your caller's telephone service providers must use caller
ID compatible equipment.
•
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 (page 4). The filter
prevents noise and caller ID problems resulting from DSL interference.
Please contact your DSL service provider for more information about
DSL filters.
�ystem does not receive caller ID when on a call.
•
Make sure you subscribe to caller ID with call waiting features from your
telephone service provider. Caller ID features works only if both you and
the caller are in areas offering caller ID service, and if both telephone
service providers use compatible equipment.
I get noise, static, or weak signals even when I'm near the
telephone base.

You may be able to improve the performance of your cordless phone
by installing your new telephone base as far as possible from any other
existing cordless telephone system that may already be installed.
