Product Use

Use two external 50W speakers on the front line.

(1) After powering on, the indicator light will light up for about 2 seconds before entering Bluetooth connection mode. At this time, the indicator light will flash rapidly (once every 1 second) for about 14 seconds.

(2) After the flash ends, enter the waiting pairing mode, and the light will flash slowly (once every 2 seconds) for a time between 40 seconds and 5 minutes. During the slow flash period, a piece of pure music is automatically played repeatedly, and after the slow flash ends, it enters the flash again, repeating this cycle. During the slow flashing period, you need to press the play/pause button with your hand to enter the flash mode and then click on the phone to pair and connect via Bluetooth. Once the Bluetooth is successfully connected to the phone, the indicator light remains on and pure music stops playing.

(3) After disconnecting the phone from Bluetooth, the light flashes rapidly for about 3 seconds before entering pure music playback mode, at which point the indicator light flashes slowly.

(4) The minimum volume can be adjusted to no sound, and when the maximum volume is adjusted, a piercing sound of clicking indicates that it has been adjusted to the maximum. To adjust the volume from maximum to minimum, press the volume down button 30 times; vice versa.
