Getting started
Registering the headset
To register the headset to an AT&T DECT cordless telephone base:
1. Make sure the battery is properly installed in the headset (see page 3). The ON/OFF light flashes twice every five seconds to indicate the headset is not registered.
2.Place the headset in the headset charger and allow it to charge for at least five
minutes before beginning registration. Leave the headset in the charger while registering the headset.
3. On the telephone base of the cordless phone, press and hold the 
HANDSET LOCATOR button until the IN USE light comes on (about four seconds) and release the button.
4.The headset registers to the telephone base automatically; this may take about 30 seconds to complete. The IN USE light on the telephone base turns off. The headset
ON/OFF light turns blue on the first headset registered. The headset ON/OFF light turns orange on the second headset registered. To verify registration was successful, press the headset ON/OFF button and check for a dial tone.
NOTE: If the registration is not successful, the ON/OFF light on the headset flashes twice every five seconds. Reset the headset and try again. Remove the headset from the charger and press ON/OFF. Then place the headset back into the headset charger. Try the registration process again.
