Deregistering headset
Deregister headset from the SynJ SB67138/SB67158 base
If you already have 10 registered devices and
need to replace or add a new device, or if you
wish to change the assigned extension numbers
of your devices, you must first deregister all
devices. You need to register each device you
wish to use again. Deregistering a cordless
handset or deskset does not remove the data
saved on that device.
Please make sure the telephone system is not
in use before deregistration. To deregister all
devices registered to the telephone base:
On the telephone base, press MENU.
Scroll down to Registration and press ENTER.
Scroll down to Deregistration and then press
ENTER.
The telephone base screen shows
Deregister all devices? <=No >=Yes. Press
REP to exit or press SKIP to continue the
deregistration.
Press SKIP . The telephone base shows
Deregistering. It takes up to 10 seconds to
complete the deregistration. The headset
light flashes slowly in red and blue. The telephone
base shows All devices deregistered and beeps when the
deregistration is successful.
