Adding handset to your telephone base
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?
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 is completed.
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 11.
NOTES:
You cannot deregister the handset(s) if any other system handset is
in use.
During deregistration, your DECT 6.0 headset(s) will also be
deregistered.
