Troubleshooting
Excessive background noise will cause a speakerphone to fade in and out.
f
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
handset mode.
When using a speakerphone, controlling background noise in your
f
environment is essential. While you are listening to your party, press
/DELETE to temporarily turn your microphone off. When it is your turn
MUTE

The charge light is off.
Make sure the power and line cords are plugged in correctly and securely.
f
Unplug the electrical power. Wait for 15 seconds, then plug it back in. Allow up
f
to one minute for the handset and telephone base to reset.
Clean the handset and telephone base charging contacts each month using
f
a pencil eraser or cloth.
My caller ID isn't working.
Caller ID is a subscription service. You must subscribe to this service from
f
your telephone service provider for this feature to work on your phone.
The caller must be calling from an area that supports caller ID.
f
Both your and your caller's telephone service providers must use caller ID
f
compatible equipment.
If you subscribe to high-speed Internet service (digital subscriber line - DSL)

telephone line cord and the telephone wall jack (see page 11). The filter
prevents noise and caller ID problems caused by DSL interference. Please
contact your DSL service provider for more information about DSL filters.

Make sure you subscribe to caller ID with call waiting features provided by

companies use compatible equipment.
