Getting started
Add and register headsets
Register a headset to an AT&T DECT cordless telephone base
1.Make sure the battery is properly installed in the headset (see page 6). The 
light on the headset flashes slowly in red and blue
to indicate the headset is not registered.
2. Place the headset in the headset charger and allow it to charge for at least one hour before beginning registration.
3.Remove the headset from the charger.
4.On the telephone base of the cordless phone, press and hold 
/HANDSET LOCATOR until the red IN USE light turns on (about four seconds) and then release the button.
5.Place the headset back to the charger.
The 
light flashes quickly in red and blue.
It takes about 60 seconds to complete the registration process. The 
light turns red when the headset is registered but not fully charged, or turns blue when it is registered and fully charged.
To verify the registration, press the 
button on the headset and check for a dial tone.
If the registration fails, you hear the voice prompt "Not registered" and the 
light on the headset flashes slowly in red and blue.
To reset the headset, remove it from the headset charger and try the registration process again.
NOTE: The button used for registration on your cordless telephone system may be different. Refer to your telephone user's manual for detailed information.
