During the slow flashing period, a piece of pure music is played automatically and repeatedly, and after the slow flashing period, it enters the fast flashing mode again, and so on. (To connect to Bluetooth-compatible during the slow flash, press the play/pause button by hand to enter the fast flash before clicking on the phone for Bluetooth-compatible pairing.<br /> (3) After the phone is disconnected from the Bluetooth-compatible, the light flashes for about 3 seconds and then enters the pure music mode, the light flashes slowly.<br /> (4) The minimum volume can be adjusted to no sound, when the maximum volume is adjusted, a shrill sound will be emitted to indicate that it has been adjusted to the maximum. To adjust from maximum volume to minimum volume, press the volume down button 30 times and vice versa.<br /> <br /> <p style="color:black;font-family:inherit;font-size:12px;"> <strong>Note:</strong><br /> Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
