AT&T 100 Telephone User Manual

If you have difficulty operating this phone, try the
suggestions below.
No Dial Tone
Make sure all plugs are connected properly. Inspect the
line cord connections at the modular jack and at the
telephone. 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
telephone. 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
This product comes set in the tone (TT) mode. Make sure
you choose the correct dialing method (TT/DP); touch tone
dialing will not work if you have dial pulse service.
Telephone Does Not Ring
Make sure the RINGER Volume 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.
