AT&T 7700 Cordless Telephone User Manual


 
IN CASE OF DIFFICULTY
If you have difficulty operating this phone, try the suggestions
below. If you still have trouble, call 1 800 722-9125.
If the phone does not work at all,
check these items first
Make sure the power cord is plugged into the base
and an electrical outlet.
Make sure the telephone line cord is plugged firmly into
the base unit and the telephone jack.
If the phone does not beep, or beeps four times when
you press P, the batteries might need recharging.
Make sure the battery pack is installed correctly.
If the battery pack still will not charge, replace it with
Replacement Battery 4051.
If the above suggestions do not solve the problem,
try resetting the security code (see next section).
If you hear a two-beep signal
when you try to use the handset
The handset and base are not communicating
properly. You might be out of range while attempting
to dial. Move closer to the base and try the call again.
If moving closer to the base does not help, the
handset and base might be set to different security
codes. To reset the security code, try the following:
Place the handset in the base, and check to make
sure the CHARGING light is on. Wait 15 seconds,
then pick up the handset and press P. The
phone should operate properly. If it does not,
try the next step.
Place the handset in the base, and check to make
sure the CHARGING light is on. Unplug the AC
adapter from the outlet, wait 15 seconds, then plug it
in again. The CHARGING light should go on.
Wait another 15 seconds, then pick up the handset
and press P. The phone should operate
properly. If it does not, try the next step.
Pick up the handset, open the battery compartment,
and unplug the battery pack. Wait 15 seconds,
then reinstall the battery pack, close the battery
compartment, place the handset in the base, and
check to make sure the CHARGING light is on.
Wait another 15 seconds, then pick up the handset
and press P. The phone should operate properly.
If you hear noise in the handset
and the buttons don’t work
The base unit and handset might not be set to the same security
code. Place the handset in the base for at least 15 seconds to reset
the security code.
If you have no dial tone
Check all the previous suggestions. If you still do not hear a
dial tone, disconnect the phone and try another phone in the
same jack. If there is no dial tone on that phone either, the
problem is probably in your wiring or local service. Call your
local telephone service company.
If you hear noise or interference
You may be out of range. Move closer to the base.
Press and release C to change to another of the
25 channels available. If the noise is exceptionally
loud, move closer to the base before changing channels.
Household appliances plugged into the same circuit
as the base can sometimes cause interference. Try
moving the appliance or the 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 phone does not ring when you receive a call
Make sure the handset ringer is set to ON.
Make sure the telephone line cord is connected
firmly to the base and the telephone jack. Make sure
the power cord is plugged into an outlet not controlled
by a wall switch.
You might be too far from the base. Move closer to
the base.
You might have too many extension phones on your
telephone line to allow all of them to ring. Try unplug-
ging some of the other phones.
Press C to change to another channel.
If you hear other calls
Press C to change to another channel.
Disconnect the base from the telephone jack and
plug in a corded telephone. If you still hear other
calls, the problem is probably in your wiring or local
service. Call your local telephone company.
If your telephone misdials
or you don’t hear the other person right away
It might take a few seconds for your handset to find
a good connection to the phone system. While it is
searching, the PHONE light blinks rapidly. Do not
start dialing until the PHONE light is on steadily.
If you have dial pulse (rotary) service, set the TONE/
PULSE switch on the back of the base to PULSE.
If you have tone service and you hear strange clicks
while you are dialing, set the TONE/PULSE switch
on the back of the base to TONE.
