Deregistering handsets
If you want to replace a handset, or reassign the designated
handset number of a registered handset, you must deregister
all handsets that are registered to the telephone base, and then
register each handset individually.
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 ten seconds. The telephone base screen shows
Registering... Please wait for five seconds, then it shows
Deregister all devices? Release /HANDSET LOCATOR.
3. Immediately press /HANDSET LOCATOR again or press YES.
You must press /HANDSET LOCATOR or YES within five
seconds. If the telephone base returns to idle screen, start again
with Step 1 above.
4. The telephone base shows Deregistered all devices when the
registration completes. It takes up to ten seconds to complete
the deregistration process. Before registering the handset again,
wait for the cordless handset screen to display To register HS,
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 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 handset(s) if any other system handset is in use.
Even if the battery is depleted, you can still deregister the handset by following
the steps above. After the handset is charged for at least ten minutes, the screen
shows To register HS, see manual.
