8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable not connected, faulty power adapter, power switch off. | Ensure DC 5V power cable is securely connected. Check power adapter. Turn on the power switch. |
| No sound | Volume too low, incorrect mode selected, faulty speaker connection, source device issue. | Increase volume. Verify correct mode (BT, FM, USB, TF, AUX). Check speaker wiring. Ensure audio is playing on the source device. |
| Bluetooth not connecting | Not in BT mode, device too far, already connected to another device, pairing issue. | Switch to BT mode. Ensure device is within range. Disconnect from other devices. Restart both speaker and source device. |
| Poor FM radio reception | Antenna not extended, weak signal area. | Fully extend the FM antenna. Try moving the speaker to a different location. |
| USB/TF card not playing | Unsupported file format, card/drive not inserted correctly, corrupted media. | Ensure music files are in MP3/WMA/WAV/FLAC/APE format. Reinsert USB/TF card. Try a different USB/TF card. |
| LED metronome not responding | Sensitivity too low, microphone issue. | Adjust the sensitivity potentiometer on the LED metronome PCB (Figure 7). Check microphone connection. |
9. User Tips
- For optimal sound quality, ensure all speaker connections are firm and correctly polarized during assembly.
- When using the FM radio, experiment with the antenna position to find the best reception for your location.
- The remote control provides convenient access to all functions, including mode switching, volume, and track control. Keep it handy!
- If experiencing issues with USB or TF card playback, try formatting the storage device to FAT32 and ensure only supported audio files are present.
