Troubleshooting

My caller ID features are not working properly.

•Caller ID is a subscription service. You must subscribe to this service from your local telephone company for this feature to work on your telephone.

•The caller may not be calling from an area that supports caller ID. Both you and the caller’s telephone companies must use equipment which are compatible with caller ID service.

•Make sure your service provides caller ID information when on a call. This is sometimes known as caller ID with call waiting, or type II caller ID.

•Make sure you have installed four new AA batteries properly (see Battery installation on page 6).

•If you subscribe to high-speed Internet service (digital subscriber line - DSL) 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. Please contact your DSL service provider for more information about DSL filters.
