AT&T CL80101 Cordless Telephone User Manual

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.
