After BTR5 is turned on, unlock your Android device with NFC, get BTR5 and your android device touched by the NFC detecting area to start the pairing.
(In general, the Android phone will have a pop-up prompt or sound prompt at this time.)
Note: the iPhone which has NFC function can not be paired with the BTR5 via NFC, because the NFC in iPhone is mainly used for payment.
