Deregister handsets/headsets
If you want to replace a handset or headset, or reassign the designated
handset number of a registered handset, you must deregister all handsets
and headsets that are registered to the telephone base. Then register each
handset and/or headset you wish to use individually.
To make deregistration easier, read all of the instructions on this page before
you begin.
To deregister all handsets:
Make sure that all handsets are out of the
telephone base and handset chargers before
you begin deregistration.
Press and hold
/FIND HANDSET on the
telephone base for about 10 seconds until the
IN USE light flashes.
Quickly press
/FIND HANDSET again. You
must press
/FIND HANDSET while the IN USE
light is still flashing. The
IN USE light flashes for about five seconds. If the
light stops flashing, start again with Step 1 above.
All system handsets show
Put handset on BASE to register and all
headset lights flash slowly and alternately in red and blue. You hear
a confirmation tone when deregistration completes. The deregistration
process takes about 10 seconds to complete.
If the deregistration process is successful, you hear “
Not registered
” through
the headset earpiece when you press on the headset. 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.
Pick up the registered headset and press the
RESET inset button with a
paper clip or similar object.

Unplug the power from the telephone base, then plug it back in.
