How to Pair Your Phone With Your Headset for the First Time
1 Turn on the Bluetooth feature on your phone.For most phones, select Settings/Tools > Connections >Bluetooth > On. See your phone’s user guide for more information.
2 Turn the headset on.Turn on your headset by sliding the Power Switch toward the microphone. Wait until the indicator light flashes red then blue.If you don’t see the red then blue flashes, turn the headset off, then turn it on again. Press and hold the Call Control button until you see the red then blue flashes that indicate pairing mode status.
3 Set your Bluetooth phone to ‘discover’ to locate the headset.This usually involves going to ‘setup’, ‘connect’ or ‘Bluetooth’ menu on your phone and selecting the option to ‘discover’ or ‘add a device’.
4 Once available headsets are listed, select your headset (for example 2XXPlantronics or 3XXPlantronics). If prompted for a passkey, enter 0000.When pairing is successful, the indicator on your headset flashes blue. Your phone will also confirm when pairing is complete.
