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 page 5).
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.
• Relocate 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 dial pad facing up.
I hear other calls while using my phone.
• Disconnect the telephone base from the telephone jack, and plug in
a different telephone. If you still hear other calls, call your telephone
service provider.
The telephone does not ring when there is an incoming call.
Make sure that the ringer is not off. Refer to Ringer volume on page 24 in
•
this user's manual.
• Make sure you plug in the telephone line cord securely into the
telephone base and the telephone jack. Make sure you plug in the power
cord securely.
• The cordless handset may be too far from the telephone base.
