Deregistering handsets
If you want to replace a handset, or reassign the designated
handset number of a registered handset, you must deregister
all handsets that are registered to the telephone base, and then
register each handset individually.
Please read carefully through all the instructions on this page
before beginning the deregistration process.
Deregister all handsets from your telephone base
In addition to the cordless handsets, this operation will also
deregister all cordless headsets and speakerphones registered to
your telephone base.
Press and hold on the telephone base for
about 10 seconds until the light on the telephone base
turns on and starts to flash. Then, release the button.
Immediately press again. You must press
while the light is still flashing. The
light flashes for approximately five seconds.
The deregistration takes about 10 seconds to complete. All
handsets display To register HS... and ...see manual, alternately,
if the deregistration was successful.
To register the handset(s) to the telephone base again, follow the
registration instructions on pages 9-10.
NOTES:
If the deregistration fails, you may need to reset the system and try again. To reset,
unplug the power from the telephone base and plug it back in.
You cannot deregister the handset(s) if any other system handset is in use.
Even if the battery is depleted, you can still deregister the handset by following the
steps, as mentioned above. After the handset is charged for at least ten minutes,
the screen shows To register HS... and ...see manual, alternately.

Troubleshooting
If you have difficulty with your phone, please try the following
suggestions. For Customer Service, visit our website at
www.telephones.att.com or call 1 [phone].
In Canada, dial 1 [phone].
The handset registration is unsuccessful.
Follow the handset registration instructions to register the handset
again (see Adding and registering handsets on pages 9-10).
My telephone doesn’t work at all.
Make sure the power cord is securely plugged in.
Make sure you plug the battery connector securely into the
cordless handset.
Make sure you plug the telephone line cord securely and firmly
into the telephone base and the telephone wall jack.
Charge the battery in the cordless handset for at least 10
hours. For optimum daily performance, return the cordless
handset to the telephone base or charger when not in use.
If the battery is depleted, it might take approximately 30 minutes
to charge the handset before it shows Low battery. See page 6
for details.
Reset the telephone base. Unplug the electrical power. Wait for
approximately 15 seconds, then plug it back in. Allow up to one
minute for the cordless handset and telephone base to reset.
You may need to purchase a new battery. Refer to Battery

telephone line cord may be defective. Install a new telephone
line cord.

If changing the telephone line cord does not help, the wall
jack (or the wiring to this wall jack) may be defective. Try
using a different wall jack in your home to connect your
EL52265/EL52365 telephone, or contact your telephonecontact your telephone
service provider (charges may apply).
I cannot dial out.
Try all the suggestions, as mentioned above.
Make sure you have a dial tone before dialing. The cordless
handset might take a second or two to find the telephone base
and produce a dial tone. This is normal. Wait an extra second
before dialing.
Eliminate any background noise. Noise from a television, radio or
other appliances might cause the phone to not dial out properly.
If you cannot eliminate the background noise, try muting the
cordless handset before dialing, or dialing from another room
with less background noise.
If other phones in your home are having the same problem,
contact your telephone service provider (charges might apply).
My cordless handset isn’t performing normally.
Make sure you plug the power cord securely into the telephone
base. Plug the power adapter into a different, working electrical
outlet without a wall switch.
Move the cordless handset closer to the telephone base. You
might have moved out of range.
Reset the telephone base. Unplug the electrical power. Wait for
15 seconds, then plug it back in. Allow up to one minute for the
cordless handset and telephone base to reset.
Other electronic products such as HAM radios and other DECT
phones, can cause interference with your cordless phone. Try
installing your phone as far away as possible from these types
of electronic devices.

I get noise, static, or weak signals even when I’m near the
telephone base.
If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL filter between the telephone line cord and the telephone
wall jack. The filter prevents noise and caller ID problems as
a result of DSL interference. Please contact your DSL service
provider for more information about DSL filters.
You may be able to improve the performance of your cordless
phone by installing your new telephone base as far as possible
from any other existing cordless telephone system that may
already be installed.
Other electronic products such as HAM radios and other DECT
phones, can cause interference with your cordless phone. Try
installing your phone as far away as possible from these types
of electronic devices.
Do not install this phone near a microwave oven or on the same
electrical outlet. You might experience decreased performance
while the microwave oven is operating.
If you plug your phone in with a modem or a surge protector,
plug the phone (or modem/surge protector) into a different
location. If this does not solve the problem, relocate your phone
or modem farther apart from one another, or use a different
surge protector.
Move your phone to a higher location. The phone might have
better reception in a high area.
If the other phones in your home are having the same problem,
contact your telephone service provider (charges may apply).
I experience poor sound quality when using the speakerphone.
For increased sound quality while using the speakerphone, place
the handset on a flat surface with the dialing keys facing up.

The layout of your home or office might be limiting the
operating range. Try moving the telephone base to another
location, preferably on an upper floor.
If the other phones in your home are having the same problem,
contact your telephone service provider (charges might apply).
Test a working phone at the phone jack. If another phone has
the same problem, contact your telephone service provider
(charges might apply).
Other electronic products such as HAM radios and other DECT
phones, can cause interference with your cordless phone. Try
installing your phone as far away as possible from these types
