If you have any problems with your telephone service,
determine if the problem is with your telephone or the telephone
company lines. BEFORE CALLING THE TELEPHONE COMPANY, be
aware that they may charge you for a service call if the problem
is caused by your telephone.

NO DIAL TONE

• Unplug your telephone from the wall jack. Plug a substitute
telephone that is known to work properly into the same wall
jack.
• If the problem persists when using the substitute telephone,
notify the telephone company.
• If the substitute telephone works properly, you must have your
telephone repaired before reconnecting it to the wall jack.

DIAL TONE BUT NO RINGING

• Check that the RINGER VOLUME CONTROL is not set to OFF.
• Set the RINGER VOLUME CONTROL to HIGH and have
someone on another line call you. Before answering the call,
set the RINGER VOLUME CONTROL to the desired volume.

DIAL TONE BUT NO DIALING

• Set the TONE/PULSE switch. You cannot dial out in TONE
position if you have Rotary Dial Service.
• For Rotary Dial Service, set the switch to PULSE position.
• For Tone Dial Service, set the switch to TONE position.
• Try both positions if you are not sure.
