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 (page 2). 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
may 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 may have better reception in a
high area.
•
If 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 dialing keys 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 13 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.
•
Charge the battery in the cordless handset for at least 11 hours. For optimum daily
performance, return the cordless handset to the handset charger when not in use.
•
You may have too many extension phones on your telephone line to allow all of them
to ring simultaneously. Try unplugging some of the other phones.
