Adding and registering handsets/headsets
Your telephone can support up to 12 DECT 6.0 cordless handsets (AT&T model
CL80101, sold separately) or up to 10 cordless handsets and 2 cordless
headsets (sold separately). Visit www.telephones.att.com/headsets for
a list of compatible DECT 6.0 cordless headsets. Each new handset or headset
must be registered to the telephone base before use. You must register each
handset or headset separately.
To register a cordless headset to this telephone system, please refer to the user’s
manual of the cordless headset for more details. To register a cordless handset,
see below.
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. Before you begin registration, make sure the handset is out of the telephone
base or charger and shows To register, see manual.
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 To register,
see manual. This may take up to five
minutes to occur. Please start again from
Step 1 above.
Appendix
For registration, put the handset on the
telephone base, not the handset charger.
