Deregistering handsets
If you want to replace a handset, or reassign the designated
handset number of a registered handset, you must deregister
all handsets that are registered to the telephone base, and then
register each handset individually.
Please read carefully through all the instructions on this page
before beginning the deregistration process.
Deregister all handsets from your telephone base
In addition to the cordless handsets, this operation will also
deregister all cordless headsets and speakerphones registered to
your telephone base.
Press and hold on the telephone base for
about 10 seconds until the light on the telephone base
turns on and starts to flash. Then, release the button.
Immediately press again. You must press
while the light is still flashing. The
light flashes for approximately five seconds.
The deregistration takes about 10 seconds to complete. All
handsets display To register HS... and ...see manual, alternately,
if the deregistration was successful.
To register the handset(s) to the telephone base again, follow the
registration instructions on pages 9-10.
NOTES:
If the deregistration 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 handset(s) if any other system handset is in use.
Even if the battery is depleted, you can still deregister the handset by following the
steps, as mentioned above. After the handset is charged for at least ten minutes,
the screen shows To register HS... and ...see manual, alternately.
