Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Incorrect power supply voltage or loose connection. | Check power supply (5V-24V DC) and ensure secure connection. |
| No sound output | Incorrect speaker connection, wrong input selected, or low volume. | Verify speaker polarity, select correct input source (Bluetooth, AUX, USB), and increase volume. |
| Bluetooth pairing failure | Device too far, Bluetooth not enabled, or interference. | Ensure device is within range, Bluetooth is on, and try re-pairing. Clear previous pairings if necessary. |
| Clock not synchronizing | No WiFi connection or incorrect network settings. | Ensure the device is connected to WiFi via the APP and network settings are correct. |
| Audio distortion | Volume too high, impedance mismatch, or faulty audio source. | Reduce volume, check speaker impedance, and test with a different audio source. |
