In case of difficultyIf you have difficulty with your phone, please try the suggestions below. For Customer
Service, visit our web site at www.telephones.att.com, or call 1-800-222–3111.
Telephone does
not work at all
• Make sure batteries are installed and charged correctly (see page 7).
• Make sure the AC adapter is plugged into an outlet not controlled by
a wall switch.
• Make sure the telephone line cord is plugged firmly into the base unit
and the modular jack.
• If you have dial-pulse telephone service, make sure the dial mode is
set to Pulse (see page 14).
• If these suggestions do not work, unplug the base, remove and re-
insert the batteries, then place the handset in the base to re-initialize.
Phone does not
ring
• Make sure the ringer is on (see page 13).
• Make sure the telephone line cord and AC adapter are plugged in
properly (see page 6).
• Move the handset closer to the base.
• You might have too many extension phones on your telephone line to
allow all of them to ring. Try unplugging some of them.
If you hear
noise or
interference
during a call
• You may be out of range. Move closer to the base.
• Appliances plugged into the same circuit as the base can cause
interference. Try moving the appliance or base to another outlet.
• The layout of your home or office might be limiting the operating
range. Try moving the base to another location, preferably on an
upper floor.
• If the buttons don’t work, try placing the handset in the base for at
least 15 seconds.
• Disconnect the base from the modular jack and plug in a corded tele-
phone. If calls are still not clear, the problem is probably in your
wiring or local service. Call your local telephone service company.
