To connect your ENDURE to your phone, you first need to put the headset into pairing mode:

Make sure the ENDURE is not connected to any phones (for example by turning off Bluetooth on any phone that you have previously paired with the ENDURE).
If the ENDURE is not switched on, turn it on by sliding the power switch across.
Put the ENDURE in your ear.
If this is the first time you have used the ENDURE it will go straight to pairing mode, and you will hear the voice prompts start to talk you through the process. If this does not happen, hold down the Command Button until the ENDURE announces that it is now in pairing mode.
You now need to activate Bluetooth on your phone, and use your phone’s Bluetooth menu to search for devices.

The pairing code is 0000 (four zeros).
