Replace a handset

If you want to replace a handset or reassign the designated handset number
of a registered handset, you must deregister all the handsets and then
individually register each handset.
To make deregistration easier, read all of the instructions on this page before
you begin.
To deregister all handsets:
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 base screen shows
Deregister all devices?, then release /HANDSET LOCATOR.
3. Quickly press /HANDSET LOCATOR again. You must press
LOCATOR within 5 seconds. If the telephone base returns to the idle
screen, start again with Step 1 above.
4. The telephone base shows Please wait... and then returns to the idle
screen. All system handsets show Put handset on BASE to register and
you hear a confirmation tone when the deregistration completes. The
deregistration process takes about 10 seconds to complete.
5. After deregistering, register each handset again individually. See
Adding and registering handsets (optional) on page 136.
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.
• Even if the battery is depleted, you can still deregister the handsets by following the
steps above.
