Troubleshooting
I experience poor sound quality when using the speakerphone.
For increased sound quality while using the speakerphone, place the handset on a flat
surface with the dialing keys facing up.
I hear other calls when using the telephone.
Disconnect the telephone base from the telephone wall jack. Plug in a different telephone. If
you still hear other calls, the problem is probably in the wiring or telephone service. Contact
your telephone service provider.
I hear noise on the cordless handset and the keys do not work.
Make sure the telephone line cord is plugged in securely.
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 may not be calling from an area which supports caller ID.
Both your and the caller’s telephone service providers must use equipment compatible with
the caller ID service.
The caller ID information shows after the first or second ring.
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. The filter prevents noise and caller ID problems caused by DSL
interference. Contact your DSL service provider for more information about DSL filters.
The telephone does not receive caller ID while on a call.
Make sure you subscribe to caller ID with call waiting features provided by your telephone
service provider.
The caller may not be calling from an area which supports caller ID.
Both your and the caller’s telephone service providers must use equipment compatible with
caller ID service.
