the cordless handset and base to synchronize.

Move the cordless handset closer to the telephone base. You might have 
moved out of range.

Reset the telephone base. Unplug the electrical power. Wait for 15

When using a speakerphone, controlling background noise in your 
environment is essential. While you are listening to your party, press 
MUTE/X to temporarily turn your microphone off. When it is 
your turn to speak, remember to press MUTE/X 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.

•

Disconnect the telephone base from the telephone wall jack, and plug in 
a different telephone. If you still hear other calls, the problem is probably 
in your wiring or telephone service. Call your telephone service provider 
(charges may apply).

Make sure that the ringer is not turned off. 

•

Make sure the telephone line cord is plugged securely into the telephone 
base and the telephone wall jack. Make sure the power cord is securely

•

Charge the battery in the cordless handset for at least 16 hours. For 
optimum daily performance, return the cordless handset to the telephone 
base or charger when not in use.

•

You may have too many extension telephones on your telephone line to 
allow all of them to ring simultaneously. Try unplugging one telephone at a 
time until the telephone starts ringing.

•

The layout of your home or office might be limiting the operating range. 
Try moving the telephone base to another location, preferably on an 
upper floor.

•

If the other telephones in your home are having the same problem, the 
problem is in your wiring or telephone service. Contact your telephone 
service provider (charges may apply).

•

Test a working telephone at the telephone wall jack. If another telephone 
has the same problem, the problem is the telephone wall jack. Contact 
your telephone service provider (charges may apply).
