AT&T CRL81212 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, 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 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).
The charge light is off.
Make sure you plug the power and line cords in correctly and securely.
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.
Clean the cordless handset, charger and telephone base charging contacts
each month with a pencil eraser or cloth.
The battery may not be connected to the handset or is missing completely.
Ensure that the battery is installed properly.
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 which 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 (page 5). The filter prevents
noise and caller ID problems resulting from DSL interference. Please contact
your DSL service provider for more information about DSL filters.
