Troubleshooting
If you have difficulty with your telephone, please try the sug-
gestions below. For Customer Service, visit our website at www.
telephones.att.com or call 1 (800) 222-3111. In Canada, dial 1
(866) 288-4268.
There is no dial
tone. • First, try all the above suggestions.
• The telephone line cord might be malfunctioning. Try install-
ing a new telephone line cord.
• Disconnect the telephone base from the telephone jack and
connect a different telephone. If there is no dial tone on
the telephone either, the problem is in your wiring or local
service. Contact your local telephone company.
The telephone
does not ring
when there is an
incoming call.
• Make sure the ringer is on (page 10).
• Make sure the telephone line cord and power adapter is
plugged in properly (page 5).
• There may be an extension telephone on the telephone line to
allow it to ring simultaneously. Try unplugging it.
• If the other telephones in your home are having the same
problem, the problem is in the wiring or local service.
Contact the local telephone company (charges may apply).
• Other electronic products can cause interference to your
telephone.
• Make sure the power adapter is securely plugged into an
outlet not controlled by a wall switch.
• Make sure the telephone line cord is plugged firmly into
the telephone base and the modular wall jack.
• Unplug the telephone’s electrical power. Wait for
approximately 15 seconds, then plug it back in. Allow up
to one minute to synchronize.
• Disconnect the telephone base from the modular jack
and plug in a working telephone. If this telephone does
not work, the problem is probably in the wiring or the
local service. Call the local telephone company.
