Deregister handsets
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:
Press and hold
/HANDSET LOCATOR on the
telephone base for about 10 seconds until the
IN USE light flashes, then release
/HANDSET LOCATOR.
Quickly press
/HANDSET LOCATOR again. You
must press
/HANDSET LOCATOR while the
IN USE light is still flashing. The IN USE light
flashes for about seven seconds.
If the light
stops flashing, start again with Step 1 above.
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.
If deregistration fails, you may need to reset the telephone and try again.
To reset:
Press and hold
OFF/CANCEL or place the handset back in the
telephone base.
-OR-
Unplug the power from the telephone base, then plug it back in.
After deregistering, register each handset individually. See Add and register
a handset on page 95.
NOTES:
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.
