Replace a headset
If you want to replace a headset or reassign the designated headset number of a
registered headset, you must deregister all handsets and headsets that are registered
to the same telephone base. Then register each handset and headset individually.
To make deregistration easier, read all of the instructions on this page before
you begin.
To deregister all headsets:
Press and hold /FIND HANDSET on the telephone base for about 10 seconds
until the IN USE light on the telephone base turns on and starts to ash. Then
release /FIND HANDSET.
Immediately press and release /FIND HANDSET again while the IN USE light is
still ashing. The IN USE light ashes for approximately seven seconds.
The deregistration process takes up to 10 seconds to complete. There is a
conrmation tone from the telephone base. The light ashes slowly and
alternately in red and blue when the deregistration process completes.
If the deregistration process is successful, you hear “Not registered” when you press
on the headset. If the deregistration fails, you may need to reset the telephone and
try again.
To reset:
Pick up the registered headset and press the RESET inset button with a paper clip
or similar object.
-OR-
Unplug the power from the telephone base, then plug it back in.
