Troubleshooting
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 your phone is plugged in with a modem or a surge protector, plug the
phone (or modem/surge protector) into a different location. If this doesn’t
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 when installed in a high area.
If the other phones in your home are having the same problem, the
problem is in your wiring or local 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 the
MUTE softkey to temporarily turn your microphone off. When it is your
turn to speak, remember to press the
MUTE softkey 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 off 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.
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, the problem is probably in
your wiring or local service. Call your telephone service provider.
While on a call or playing messages, there is too much noise, or the voice
sounds tinny, shrill or flat.
While on a call or playing messages, press the EQ button on the side of
the handset until you find the settings that sounds the best (page 77).
