AT&T CL80101 Cordless Telephone User Manual

My calls cut in and out while I’m using my cordless handset.
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 surge protector, try
plugging 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 telephone base to a higher location. The phone
might have better reception when installed in a high area.
If other phones in your home are having the same problem,
contact your telephone service provider (charges may apply).
My caller ID isn’t working.
Caller ID is a subscription service. You must subscribe to this
service from your telephone service provider for this feature to
work on your phone.
The caller may not be calling from an area that supports caller ID.
Both your and your caller’s telephone service providers must
use caller ID compatible equipment.
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
resulting from DSL interference. Contact your DSL service
provider for more information about DSL filters.
