★Common problem★

1. The problem of Bluetooth connection failure.
answer:
The Bluetooth indicator flashes regularly when working normally. If it is on or off, there may be a problem with the Bluetooth 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 mobile phone can connect and play music, it means that there is no problem with the Bluetooth amplifier board. It may be that the Bluetooth driver of the computer has a problem. The version is too old or there are files missing. It is recommended to uninstall and then install the latest version of the driver from the beginning.
3. The sound is stuck when the volume is turned up, intermittently, and it can be played normally after the volume is turned down.
answer:
One of the reasons: the power or power is too low, whether the voltage or current is too low.
The third reason: If the power supply is okay, it may be that the power of the speaker is too small, such as outputting 5W, but connecting a 1W speaker. When the volume is turned up, there will be a stuck phenomenon, and the speaker may be burned out.
4. There is too much noise when playing music, or there is noise when not playing music.
answer:
The function of the power amplifier board is signal amplification. The main source of noise is the radio clutter in the environment that 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 test or change the speaker test . If there is still noise, contact customer service to send it back for inspection, replacement or repair.
