5. Why I cannot connect my Bluetooth headphone to the M7?

A: When using the Bluetooth headphone with the M7 for the first time, you need pair the two devices. Please make sure that the Bluetooth headphone is in pairing mode (just like the very first time that you use the Bluetooth headphone with other devices). When the Bluetooth headphone is in pairing mode,  turn on Bluetooth on the M7 and search for the headphone to connect.
