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 handsets (optional)

To register a handset:
1. Make sure the handset is out of the telephone base or charger and shows
Put handset on BASE to register before you begin registration.
2. Put the handset you wish to register on the telephone base cradle, not
the charger.
3. The handset displays Registering handset..., and the telephone base screen
displays Registering... Please wait. It takes about 90 seconds to complete the
registration process. The screens display HANDSET X Registered (X represents
the registered handset number), and beeps when registration completes.
If registration fails, the system will automatically try to register again. If
it fails after the third try, the handset displays Registration failed, then
Put handset on BASE to register. The telephone base screen displays
Registration failed and then returns to the idle screen. 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.
