Troubleshooting
The charge light is off.
• Make sure you plug the power and line cords in correctly and securely.
• Unplug the electrical power. Wait for 15 seconds, then plug it back in. Allow up to
one minute for the cordless handset and telephone base to reset.
• Clean the charging contacts on the cordless handset and telephone base each
month with a pencil eraser or cloth.
My caller ID isn't 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 phone.
• The caller must 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 2). The filter prevents noise and caller ID problems
resulting from DSL interference. Contact your DSL service provider for more
information about DSL filters.
My telephone 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 feature works only if both you and the caller are in
areas offering caller ID service, and if both telephone service providers use
compatible equipment.
The messages on the answering system are incomplete.
• If a caller leaves a very long message, part of it may be lost when the system
disconnects the call after the preset recording time.
• If the caller pauses for too long, the system stops recording and disconnects
the call.
• If memory on the answering system becomes full during a message, the system
stops recording and disconnects the call.
• If the caller's voice is very soft, the system may stop recording and disconnect
the call.
The messages are very difficult to hear.
Tap VOL+ on the telephone base, or press /VOLUME on the cordless handset to
•
increase the listening volume.
