Replace a handset
If you want to replace a handset or reassign the designated handset number of
a registered handset, you must deregister all the handsets and then individually
register each handset.
To make deregistration easier, read all of the instructions on this page before
you begin.
To deregister all handsets:
Press and hold
FLASH
on the telephone base for about 4 seconds until it
shows
Deregister all handsets?
.
Then, release the button.
Press the
YES softkey to continue. You hear a confirmation tone from the
telephone base.
The telephone base displays
PLEASE WAIT...
. All system handsets show
Out of range OR no power at base
for a few seconds, and then you hear a
confirmation tone from the handset.
All the handsets show
Press [HOLD] on base for 4 sec, then press [#] on
handset
when the deregistration completes. The deregistration process
takes about 10 seconds to complete.
If deregistration fails, you may need to reset the telephone and try again.
To reset:
Unplug the power from the telephone base, then plug it back in.
After deregistering, register each handset individually. See
Add and register a
handset
on page 135.
