Deregister all devices
If you want to replace a device, or reassign the designated handset
number of a registered handset, you must deregister all devices that are
registered to the telephone base. Then register each device individually.
To make deregistration easier, read all of the instructions on this page
before you begin.
To deregister all devices:
Press and hold
FIND HS
at the side of the telephone base for about
10 seconds until the
IN USE
light starts to flash and the telephone
base shows

followed by

devices?
, then release
FIND HS
.
Immediately press
YES
or
FIND HS
.

To register HS, see manual.
The deregistration
process takes about 10 seconds to complete.
To register the handset(s) or pendant(s) to the telephone base again,
follow the registration instructions from page 15 to page 17.
You cannot deregister all devices if any other system device is in use.
If deregistration fails, you may need to reset the system and try again.
To reset, unplug the power and the telephone line cord from the
telephone base and remove the backup battery. Then plug the cords
back in and install the backup battery again.
Even if the battery is depleted, you can still deregister all handsets
by following the steps above. After the handset is charged for at
least 10 minutes, its screen shows
