Troubleshooting
I experience poor sound quality when using the speakerphone.
• For increased sound quality while using the telephone speakerphone, place
the telephone base on a flat surface.
• 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 stop speakerphone operation and return
to normal corded handset mode.
• When using a speakerphone, controlling background noise in your
environment is essential. While you are listening to your party, press MUTE
to temporarily turn your microphone off. When it is your turn to speak,
remember to press MUTE again to turn the microphone on.
I hear other calls while using my telephone.
• 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.
My telephone base does not ring when I receive a call.
• Make sure that the ringer is not off. Refer to the section on ringer selection
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.
• You may have too many extension telephones on your telephone line to allow
all of them to ring simultaneously. Try unplugging some of the other telephones.
• If the other telephones in your building are having the same problem,
contact your telephone service provider.
• Test a working telephone at the telephone jack. If another telephone has
the same problem, contact your telephone service provider.
• 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.
• Your line cord might be malfunctioning. Try installing a new line cord.
