Deregister handsets
You may need to deregister your handsets if:
You have 12 registered handsets, and need to replace a handset.
-OR-
You wish to reassign the designated handset number of your
registered handsets.
You must first deregister all handsets, and then register each
handset you wish to use again, one at a time.
Please read carefully through all the instructions on this page
before beginning the deregistration process.
Deregister all cordless handsets from the telephone base
All devices, including cordless headsets paired
to your telephone base, will be deregistered
after the deregistration process.
Make sure that all handsets are out of the
charger before you begin deregistration.
Press and hold HOLD on the telephone
base for about 10 seconds. The telephone
base shows Deregister all devices?
Release HOLD.
Quickly press HOLD again or press YES within
5 seconds. If the telephone base returns to the
idle screen, start again with Step 1 above.
The telephone base shows Deregistered all
devices and then returns to the idle screen.
All system handsets display To register HS, see manual,
and you hear a confirmation tone when the deregistration
completes. The deregistration process takes about 10 seconds
to complete. After deregistering, register each handset again
individually following the registrations on the previous page.
NOTES:
If the deregistration process 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.
You cannot deregister the handsets if any other system device is in use.
