IN CASE OF DIFFICULTY

If this telephone does not work properly, try the following suggestions before seeking repair assistance.

No Dial Tone

☞Make sure all plugs are connected properly. Inspect the line cord connections at the modular jack and at the tele- phone. Also inspect the coiled handset cord connections at both ends.

☞Unplug the telephone and connect it to another modular jack. If it still does not work, try another telephone; if neither telephone works, the problem is not in this tele- phone. The trouble may be caused by local telephone company lines, central office equipment, or the wiring in your home.

Calls Cannot Be Dialed, or Are Dialed Slowly

Reset Dial Mode switch. If you have rotary service, you cannot dial numbers with the switch set to TONE. Set the switch to PULSE, then hang up and dial again.

If you have tone dialing service, you can use either tone or dial-pulse mode. If you set the switch to TONE, numbers are dialed much more quickly.

Telephone Does Not Ring

☞Make sure the Ringer switch is not set to OFF.

☞If there are several other phones on the same line, try disconnecting some of the other telephones. Having too many telephones can also create problems such as low ringer volume or impaired quality during calls.
