Adding and registering handsets
Your telephone can support up to 12 cordless handsets
(AT&T model CL80101, sold separately). The handset must be
registered to the telephone
base before use. You must register
each handset separately.
The handsets provided within your product box are already
registered as
HANDSET 1 and so forth. Additional handsets are assigned
numbers in the sequential order they are registered (up to
HANDSET 12).
Register a handset to your telephone base
1. Make sure the handset is out of the telephone base or
charger and shows
Put HS on BASE to register before you
begin registration.
2.
Put the handset you wish to register on the telephone
base cradle.
3. The screen shows
Registering... Please wait and the
IN USE light turns on. It takes up to 90 seconds to complete
registration. Then
HANDSET X Registered appears on the
screen, with
HANDSET being the handset name and X being
the handset number (
1-12). The handset beeps and the
IN USE light turns off. The handset is
now registered with the telephone base.
If registration fails, the system will
automatically try to register again. If
registration fails after the third try,
Registration failed appears on the screen
for a few seconds and then
Put HS on
BASE to register. This may take up to five
minutes to occur. Please start again from
Step 1 above.
NOTE: You cannot register a handset if any other
system handset is in use.
