Adding and registering handsets/headsets/speakerphones
Your telephone can support up to 12 DECT 6.0 cordless handsets (AT&T
model CL80104, sold separately) or up to 10 cordless handsets and two
cordless headsets or speakerphones (sold separately). Visit
www.telephones.att.com/headsets for a list of compatible
DECT 6.0 cordless headsets. Each new handset, headset or speakerphone
must be registered to the telephone base before use. You must register each
handset, headset or speakerphone separately.
To register a cordless headset or speakerphone to this telephone system,
please refer to the corresponding user’s manual for 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 HS, 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. HANDSET X
Registered appears on the screen, with 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 HS, see manual. This may take up to
five minutes to occur. Please start again from Step 1 above.
For registration, put the handset on the
telephone base, not the handset charger.
