The charge light is o.
Make sure the power cord is plugged in correctly and securely.
Make sure the battery is installed correctly in the handset. Follow the instruction in
Battery installation on page 4 to install the battery.
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 and telephone base charging contacts each month using
a pencil eraser or cloth.
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 lter between the telephone line cord
and the telephone wall jack (see Installation on page 3). The lter prevents noise
and caller ID problems caused by DSL interference. Please contact your DSL service
provider for more information about DSL lters.
Other electronic products, such as computers, wireless routers, microwave ovens
and other cordless telephones can interfere with the performance of your cordless
telephone. You may be able to improve the performance of your telephone by
installing the telephone base as far away as possible from other electronic devices.
Do not install this telephone near a microwave oven or on the same electrical outlet.
You may experience decreased performance while the microwave oven is operating.
If your telephone is plugged in with a modem or a surge protector, plug the telephone
(or modem/surge protector) into a dierent location. If this doesn’t solve the
problem, relocate your telephone or modem farther apart from one another, or use a
dierent surge protector.
Relocate your telephone to a higher location. The telephone will likely have better
reception when installed in a high area.
If the other telephones in your home are having the same problem, the problem is in
your wiring or telephone service. 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 at
surface with the dial pad facing up.
When using a speakerphone, controlling background noise in your environment is
essential. While you are listening to your party, press MUTE/DELETE to temporarily turn
your microphone o. When it is your turn to speak, remember to press MUTE/DELETE
again to turn the microphone on.
Excessive background noise will cause a speakerphone to fade in and out. Try
controlling the background noise by turning o any audio devices near the
speakerphone. Also, try to avoid interrupting the person at the other end of the
conversation while they are speaking. If background noise cannot be controlled, you
should terminate speakerphone operation and return to normal handset mode.
