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 at surface with the dial pad facing up.
My caller ID isn’t working.
f 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.
f The caller may not be calling from an area that supports caller ID.
f Both your and your caller’s telephone service providers must use
caller ID compatible equipment.
f If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL lter between the telephone line cord and the telephone
wall jack (page 8). The lter prevents noise and caller ID
problems resulting from DSL interference. Please contact your
DSL service provider for more information about DSL lters.
System does not receive caller ID when on a call.
f 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 oering 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.

f 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.
