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. 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 handset speakerphone.
•
For increased sound quality while using the handset 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, contact your telephone service provider.
The telephone does not ring when there is an incoming call.
•
Make sure that the ringer is not set to off (page 13).
•
Make sure the telephone line cord and power adapter are plugged in properly (page 2)
•
The cordless handset may be too far from the telephone base. Move it closer to the
telephone base.
•
You may have too many extension phones on your telephone line to allow all of them to ring
simultaneously. Try unplugging some of them.
