Replace a headset
If you want to replace a headset, you must deregister the headset that is registered to
the telephone base.
To make deregistration easier, read all of the instructions on this page before you begin.
To deregister the headset:
1. Ensure the headset is in the charger.
2. On the telephone, press MENU and then select User settings > DECT headset.
3. On the telephone’s DECT headset menu, select 2. Deregister.
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. The deskset screen displays “DECT headset is deregistered”. If
the deregistration fails, you may need to:
• remove and replace the headset in the charger and repeat the deregistration
instructions.
-OR-
• reset the headset and repeat the deregistration instructions.
To reset:
• Pick up the registered headset and press the RESET inset button with a paper clip
or similar object.
You cannot deregister a headset if any system handset or headset is in use.
