Your telephone can support up to 12 DECT 6.0 cordless handsets (AT&T
model TL90071, sold separately) or up to 10 cordless handsets and 2
cordless headsets (sold separately). Visit
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).

Add and register a handset (optional)

To register a handset:
1. Make sure the handset shows Put handset on BASE to register.
2. Put the handset you wish to register on the telephone base cradle, not
the charger.
3. The handset displays Registering handset... on the handset and the red
IN USE light on the telephone base turns on. It takes about 90 seconds
to complete the registration process. The handset displays HANDSET X
Registered (X represents the registered handset number). The IN USE light
turns off and the handset beeps when registration completes.
If registration fails, it will automatically try to register again. If it fails after
the third try, the handset shows Registration failed, then Put handset on
BASE to register. This may take up to 5 minutes to occur. When the handset
displays Put handset on BASE to register, please start again from
Step 1.
NOTES:
• You cannot register a handset if any other system handset is in use.
• If you try to register more than 12 handsets to the telephone base, the telephone base
shows Registration slots are full and sounds 2 beeps.
