Deregistering handsets

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.

Deregister all handsets from the telephone base

1. Make sure that all handsets are out of the

chargers before you begin deregistration.

2. Press and hold /HANDSET LOCATOR on the

telephone base for about 10 seconds. The

IN USE light turns on after about four seconds.

Keep holding /HANDSET LOCATOR until the

screen shows Deregister all devices? and the IN USE light begins to

flash. Release /HANDSET LOCATOR.

3. Immediately press /HANDSET LOCATOR or MENU/SELECT while the

IN USE light is still flashing. (If the light stops flashing, start again with

Step 1 above.)

4. It takes up to 10 seconds to complete the deregistration process. Before

registering the handset again, wait for the cordless handset screen to

display To register, see manual.

5. To register the handset(s) to the telephone base again, follow the

registration instructions on the previous page.

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. Any call activity

will cancel the deregistration process.

Even if the battery is depleted, you can still deregister the handsets by following the steps

above. After the handset is charged for at least 10 minutes, the screen shows To register,

see manual.
