Expansion handset
Adding and registering handsets (optional)
Handsets purchase separately (AT&T CL80109) need to be
registered to the telephone base before use. When first
purchased, all expansion handsets show NOT REGISTERED
on the screen. New handset may need to be charged
without interruption for at least 10 minutes before
registering to the telephone base.
To register a handset to your telephone base
1. Make sure the handset is out of the telephone base or charger and shows
NOT REGISTERED before you begin registration.
2. Press and hold
HANDSET LOCATOR on the
telephone base for about four seconds (until the red IN
USE light on the telephone base is on) and then release
the button. The IN USE light remains on while the
telephone base attempts to register a handset.
3. Place the unregistered handset into the telephone base
or charger, PRESS HNDST LOC 4 SEC ON BASE shows
on the handset screen. The handset is now registering
with the telephone base. The handset then shows
PLEASE WAIT... and it takes up to 60 seconds to
complete the registration. There is a beep sound when
the registration is successful. The handset shows
HANDSET X REGISTERED, with X being the handset
number (1-12).
NOTES:
1. If the registration is not successful, the screen shows NOT REGISTERED. To reset the
handset, remove the handset from the telephone base or charger, then start again
from step 2 above.
2. You cannot register a handset if any other system handset is in use.
