Troubleshooting
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 (see Telephone base
and charger installation on page 4). The filter prevents noise and caller
ID problems caused by DSL interference. Please contact your DSL service
provider for more information about DSL filters.
• 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 different location. If this
doesn't solve the problem, relocate your telephone or modem farther apart
from one another, or use a different surge protector.
• Move 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 flat 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
