Deregister devices

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 the desired device(s) first, then register the
device(s) you wish to use, one at a time. Deregistering a cordless handset or
deskset does not remove the data saved on that device. Please read all the
instructions on this page before beginning the deregistration process.
Please make sure the telephone system is not in use before deregistration.

1. On the telephone base, press MENU

screen prompts if you want to deregister that device. If

deregistration. When the deregistration is successful,
there is a confirmation tone and the telephone base
shows the deregistration completion message.
NOTES:
