Before using the wireless headset with any Bluetooth devices for the first time, you will need to pair them together. For example, it can be paired with Bluetooth mobile phones, Bluetooth stereo devices such as MP3 players, or motorcycle-specific Bluetooth GPS navigation, and with other Boom! Audio Bluetooth headsets. This pairing operation is only required once for any Bluetooth device. The headset remains paired with the devices and automatically reconnects to them when they are within range. You will hear a high tone single beep and a voice prompt when the headset connects to the paired device automatically:
When a headset is paired to the motorcycle, it will say Your Headset is Paired, Boom! Audio Connected. After this initial pairing, every time the headset connects to the motorcycle you will hear Boom! Audio Connected.
When a headset is paired to a phone, it will confirm the pairing by saying Your Headset is Paired. After this initial pairing, every time the headset reconnects to the phone it will say Phone Connected.
