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 the 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 your telephone base

1.Make sure that all handsets are out of the telephone base and chargers before you begin deregistration.

2.Press and hold /HANDSET LOCATOR on the telephone

base for about 10 seconds (until the IN USE light starts to flash), then release the /HANDSET LOCATOR button.

3. Immediately press /HANDSET LOCATOR while the IN USE light is still flashing. (The light flashes for about

seven seconds. If the light stops flashing, start again with Step 1 above.)

4.It takes up to 10 seconds to complete the deregistration process. Wait for the cordless handset screen to display To register, see manual before registering the handset again.

5.To register the handset(s) to the telephone base again, follow the registration instructions on the previous page.

NOTES:

•If the deregistration process is not successful, you might 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 handset(s) if any other system handset is in use.

•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.
