AT&T 7710 Cordless Telephone User Manual


 
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.
If the handset battery status icon is partly displayed,
the battery needs recharging.
Make sure the battery pack is installed correctly.
If the battery pack will still not charge, replace it with
Lucent Technologies 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 re-
install 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 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 you wiring or local service. Call your
local telephone service company.
If you hear noise or interference
when using the phone
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 switch 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
unplugging some of the other phones.
Press C to change to another channel.
If you hear other calls while using the phone
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 service 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 con-
nection to the phone system. While it is searching, the PHONE
light blinks rapidly. Do not start dialing until the PHONE light is
on steadily.
