HANDSET X
REGISTERED
Adding and registering handsets (optional)
Handsets purchased separately (AT&T TL90078)
need to be registered to the telephone base before
use. When first purchased, all expansion handsets
will show NOT REGISTERED on the screen. The new
handset(s) may need to be charged for five minutes
before registering to the telephone base.
To register a handset to your telephone base
1. Place the unregistered handset into the telephone
base. If PRESS HNDST LOC 4 SEC ON BASE does
not appear on the handset screen after a few
seconds, remove the handset and place it in the
telephone base again.
2. On the telephone base, press and hold
HANDSET LOCATOR for about four seconds
(until the red IN USE light on the telephone base
turns on) and then release the button. The handset
will show PLEASE WAIT... and it will take about 10
seconds to complete the registration. The handset
will display HANDSET X REGISTERED, with X being
the handset number (1-12). There will be a beep
sound if the registration is successful.
NOTES:
1. If the registration is not successful, the display will show NOT
REGISTERED. To reset the handset, remove the handset from the
telephone base and place it back in. Try the registration process
again.
2. You cannot register a handset if any other system handset is in
use.
