Troubleshooting
| Problem | Solution |
|---|---|
| Device does not turn on. | Ensure the device is fully charged. If the battery is completely drained, it may take a few minutes for the charging indicator to appear. |
| Cannot transfer files to the device. | Ensure the USB cable is securely connected to both the device and the computer. Try a different USB port or cable. Make sure to safely eject the device after transfer. Some users report better success by transferring one album at a time and avoiding USB hubs. |
| Bluetooth connection is unstable or fails. | Ensure the MP3 player and the Bluetooth audio device are within range. Turn off and on Bluetooth on both devices. Try re-pairing the devices. Ensure no other strong wireless signals are causing interference. |
| Music files are not recognized or play incorrectly. | Verify that the music files are in a supported format (MP3, WMA, WAV, APE, FLAC). Ensure files are placed in the "Music" folder. Reformat the Micro SD card if issues persist (this will erase all data). |
| Device freezes or becomes unresponsive. | Press and hold the power button for approximately 10-15 seconds to force a restart. If the issue persists, try resetting the device (refer to the full user manual for specific reset instructions if available). |
