Replace a handset
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. Then register each handset individually.
To make deregistration easier, read all of the instructions on this page before
you begin.
To deregister all handsets:
Press and hold FIND HANDSET at the side of the telephone base for about
10 seconds until the telephone base shows Registering... then De-register?
The IN USE light flashes.
Immediately press and release SELECT or FIND HANDSET. The telephone base
displays Please wait.
All handsets show To register HS... and ...see manual alternately when the
deregistration process completes. The deregistration process takes about
10 seconds.
To register the handset(s) to the telephone base again, follow the registration
instructions on the previous page.
You cannot deregister all handsets if any other system handset is in use.
If 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.
Even if the battery is depleted, you can still deregister all handsets by following
the steps above. After the handset is charged for at least 10 minutes, its screen
alternately shows To register HS... and ...see manual.
