Troubleshooting Tips:

• Bluetooth-Compatible Connection Failure: The Bluetooth-compatible indicator light should flash regularly when the board is working correctly. If it stays on or doesn't light up, please contact our customer service team for assistance.
• Failure to Connect with Laptop/Desktop: If your phone can connect and play music, but your laptop or desktop computer cannot, it may be due to an outdated Bluetooth driver or missing file. We recommend uninstalling the current driver and downloading the latest version for your computer.
• Sound Stuck/Intermittent Volume: If you experience sound issues such as intermittent sound or sound that only plays correctly after turning down the volume, it may be due to insufficient power supply causing low voltage or current. Ensure that the power supply is adequate and that the connected speaker's power output matches the amplifier board's output power.
• Excessive Noise or Bottom Noise: While a little noise is normal, excessive noise may indicate a faulty power supply or speaker. Try changing the power supply or speaker to troubleshoot the issue. If the problem persists, please contact our customer service team for further assistance.
