This setting may be made with the handsets only. Deregistration
cancels registration. During the de-registration process, keep the
handset near the base.

1. If necessary, press the MUTE/program button to go to the

DEREGISTRATION menu. The default is 2 NO.

2. Use the touch-tone pad to select 1 for  YES or 2 for NO. Or use the cid/

vol (up and down arrow) button to scroll to 1 YES or 2 NO.

 It is not recommended that a handset be de-registered unless

absolutely  necessary because once a handset is de-registered,  that handset's
telephone features cannot be used  until the handset  is re-registered.

the display.

 Press the EXIT button once to keep the previous setting and return to

the standby screen.

REGISTER ..... shows in the display followed by a confirmation tone.
Then HANDSET X DEREGISTERED shows in the display to confirm the

REGISTRATION shows in the display. To use the handset, you must register
the handset.

If one or more handsets becomes lost, you should de-register all handsets
to ensure proper system operation. Follow the steps below to deregister
both handsets at the same time.
