AT&T 135 - Manual (Page 8)

IN CASE OF DIFFICULT Y
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.
Other Problems
Make sure you have followed all the instructions in
this manual. If you continue to have problems, call
1 800 722-9125. If you cannot correct the problem, discon-
nect the telephone and refer to the warranty information.
