Common Problem:
1. The problem of Bluetooth-compatible connection failure.
Answer: The Bluetooth-compatible indicator light flashes regularly when it is working normally. If it stays on or does not light up, there may be a problem with the Bluetooth-compatible module. You can contact customer service to deal with it.
2. The mobile phone can be connected but the laptop or desktop computer cannot be connected.
Answer: If the phone can connect and play music, it means that there is no problem with the Bluetooth-compatible power amplifier board. It may be that there is a problem with the computer's Bluetooth driver, the version is too old, or the file is missing. It is recommended to uninstall and then install the latest version of the driver.
3. When the volume is turned up, the sound will be stuck, intermittently, and it can be played normally after the volume is turned down.
Answer: One of the reasons: whether the voltage or current is too low caused by the power of the power supply is too small.
The third reason: If the power supply is ok, it may be that the power of the speaker is too low. For example, if the output is 5W, but a 1W speaker is connected, and the volume is turned on, the phenomenon of freezing will occur, and the speaker may be burned out.

4. There is too much noise when playing music, or there is a bottom noise when no music is played.
Answer: The function of the power amplifier board is to amplify the signal. The main source of noise is that the radio clutter in the environment is amplified by the power amplifier board, so a little noise is normal. If the noise is too large, you can change the power supply to test, or change Speaker test. If there is still noise, please contact customer service and send it back for inspection, replacement or repair.
