Tips:
(1). Low battery alarm: When the low voltage battery is less than 3.3V, the bluetooth device will automatically alarm, and the red light will flashes every 2 minutes. Also, if the battery is lower than 3V, the device will shut down automatically.
(2). Device charging: When the device is in low battery or unable to turn on, you could use the USB cable to charge it via the charging port. The red light will be on when the bluetooth adapter is in charging and be off automatically when the battery is fully charged.
(3). The working voltage of the bluetooth adapter for Beats Solo 2 is in the range from 3.0V to 4.2V. If it will not be used for a long time or in low battery, it also should be charged timely to prevent the receiver from working abnormally or damaging the battery’s lifetime.
(4). Since the signals of wireless bluetooth will be blocked and absorbed by the surroundings , try to place it in a barrier-free position during use, so that you could enjoy better high-quality music.
