The Bluetooth audio device must be paired with the 10U. The 10U supports the Audio/Video Remote Control Profile (AVRCP), so if your Bluetooth audio device also supports the AVRCP, you can use the 10U to remotely control music playback. Not only can you adjust the volume but you can also use functions such as play, pause, next track and previous track.
1. To play or pause music, press the Joystick for 1 second until you hear a double beep.
2. To adjust the volume, move the Joystick up or down
3. To track forward or track back, move and hold the Joystick for 1 second left or right.
