You may need to deregister your handsets if:

You have 12 registered handsets and need to replace a

handset.

-OR-

You wish to change the designated handset number of your

registered handsets.

You must first deregister ALL handsets, and then register each

handset you wish to use again, one at a time.

Please read carefully through all the instructions on this

page before beginning the deregistration process.

Make sure that all handsets are out of the telephone base and

chargers before you begin deregistration.

Press and hold /HANDSET LOCATOR on the telephone

base for about 10 seconds until the IN USE light flashes, then

release /HANDSET LOCATOR.

Quickly press /HANDSET LOCATOR again. You must press

/HANDSET LOCATOR while the IN USE light is still flashing.

The IN USE light flashes for about seven seconds. If the light

stops flashing, start again with Step 1 above.

and you hear a confirmation tone when the deregistration

completes. The deregistration process takes about 10 seconds

to complete.

NOTES:

If the deregistration process fails, you may need to reset the system and

try again. To reset, unplug the power from the telephone base and plug it

back in.

You cannot deregister the handsets if any other system handset is in use.
