Common problem:

1. The problem of Bluetooth connection fai.

Answer: The bluetooth 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 module.

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 power amplifier board. It may be that there is a problem with the computer's Bluetooth driver, the version is too old or there are files miing. 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: the power is too small, check whether the 18650 battery is installed and whether the voltage is too low, you can replace it with a new battery to test;

Reason 2: There is no 18650 battery installed, and the charging port is used to supply power directly, because when this product is charging, the current that the power ch can pa through is relatively small (about 200mA). After the sound is turned on, the power supply will be insufficient, causing the speaker Caton. But you can connect the power supply directly to the battery holder, skping the limitation of the charging ch.

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 3W, but a 1W speaker is connected, and the volume is turned on, there will be a freeze phenomenon, 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 bit of noise is normal. If the noise is too large, you can change the power supply to test, or change Speaker test.
