IN CASE OF DIFFICULTY

Tone Signals Do Not Activate a Remote Device

•Tone signaling does not work during conference calls.

•The phone generates tones of fixed duration, which may not be long enough to activate some devices such as answering machines.

Operation During a Power Failure

This phone will operate during a power failure if a charged battery has been installed. You will be able to dial and answer calls with the handset or headset, but no other features will work until power is restored.

No Caller ID Information While on a Call

•You must subscribe to combined Caller ID with Call Waiting as a single service to see Call Waiting information.

•Make sure the TEL SET and TEL LINE cords are not reversed.

Display Screen is Blank

Make sure the power cord is connected to both the phone and an electrical outlet not controlled by a wall switch.

No Caller ID Information Received

Caller ID information is transmitted by the telephone company between the first and second rings. Allow your phone to ring at least twice to receive Caller ID information.

IN CASE OF DIFFICULTY

Screen Displays COVM

•If you do not subscribe to Voice Mail service, turn off the COVM indicator for each line.
