the telephone line cord and the telephone wall jack (page 4). The filter prevents noise and caller ID problems as a result of DSL interference. Please contact your DSL service provider for more information about DSL filters.

•Do not install this phone near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating.

•If you plug your phone in with a modem or a surge protector, plug the phone (or modem/surge protector) into a different location. If this does not solve the problem, relocate your phone or modem farther apart from one another, or use a different surge protector.

•If other phones in your home are having the same problem, contact your telephone service provider (charges may apply).

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 call 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.

System 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.

Incomplete messages.

•If a caller leaves a very long message, part of it may be lost when the system disconnects the call after the recordings exceed the maximum recording time (page 39).

•If the caller pauses for longer than three seconds, the system stops recording and disconnects the call.

•If the system’s memory becomes full during a message, the system stops recording and disconnects the call.
