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.
To make deregistration easier, read all of the instructions on this page before you begin.
Deregister all handsets from the 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

the
IN USE
light on the telephone base turns on and starts to flash. Then,
release
FIND HS
.
Immediately press
FIND HS
again while the
IN USE
light is still flashing.
The
IN USE
light flashes for approximately five seconds.
The deregistration takes about 10 seconds to complete. All handsets display

alternately, if the deregistration was successful.
To register the handset(s) to the telephone base again, follow the registration
instructions on the previous page.
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 handsets if any other system handset is in use.
Even if the battery is depleted, you can still deregister the handsets by following the steps
mentioned above. After the handset is charged for at least ten minutes, the screen shows
