Troubleshooting

Display screen is blank.

•Make sure you have properly installed four working alkaline batteries (See Battery installation on pages 4-5).

Operation during a power failure.

•This telephone operates during a power failure if a telephone line cord is plugged between the telephone wall jack and the telephone base. You are able to answer calls with the handset, and make calls using the dialing keys. No other features work unless batteries are installed. All settings in menu options are retained during a power failure if a telephone line cord is plugged between the telephone wall jack and the telephone base.

•If you neither install batteries nor a telephone line, after a few minutes, the telephone clears the directory, caller ID history, speed dial memory, and the last number dialed memory. At the same time, all settings in menu options change back to their default settings.

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 that supports caller ID.

•Both your and the caller’s telephone service providers must use equipment compatible with caller ID service.

•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 6). The filter prevents noise and caller ID problems caused by DSL interference. Please contact your DSL service provider for more information about DSL filters.

•Make sure the area codes are set correctly (see Home area code on page 13 and Local area code on page 14).

•Reset the telephone. See Common cure for electronic equipment on page 41.

The telephone does not receive caller ID or the telephone does not display caller ID during call waiting.

•Make sure you subscribe to caller ID with call waiting features provided by the telephone service provider.
