Pairing the headset with a compatible phone
Pairing is the process of linking the headset with a Bluetooth-enabled
mobile phone. After you pair the headset with a phone, you can only
use the headset with the paired phone. If you want to use the
headset with a different phone, you must repeat the pairing process
with the new phone. The headset can be paired with up to eight
compatible phones, but it can be connected to only one phone at a
time.

1 Make sure that a compatible phone is turned on and within 33
feet (10 meters) of the headset.

charged.
3 Press and hold the Power/Send/End button for about four seconds.
The indicator rapidly flashes green.
4 Release the button. The headset is now in pairing mode.
