Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or no charge. | Connect the device to a power source using the Type-C cable and charge it for at least 30 minutes before attempting to power on again. |
| No sound from speaker. | Volume too low; device muted; incorrect audio source selected; faulty media file. | Increase volume; check mute settings; ensure correct input source (Bluetooth, TF, USB, AUX) is selected; try a different media file. |
| Bluetooth connection fails. | Speaker not in pairing mode; device too far; interference; previously paired device. | Ensure speaker is in Bluetooth pairing mode; move devices closer; turn off other Bluetooth devices; forget the device on your phone and re-pair. |
| FM radio reception is poor. | Weak signal; environmental interference. | Move to an open area; try adjusting the device's position; perform an automatic station scan. |
| Media files not playing from TF card/USB. | Incompatible file format; corrupted file; improperly inserted card/drive. | Ensure files are in supported formats (e.g., MP3, MP4); check if the card/drive is inserted correctly; try reformatting the storage device (this will erase data). |
User Tips

- Storage Capacity: The device itself does not have significant internal storage for media. It relies on external TF cards or USB flash drives for storing music and videos. Ensure you have a compatible storage device inserted for media playback and recording.
- Language Settings: If the display language is not English, navigate to the 'Settings' menu (often represented by a gear icon) and look for a 'Language' option to change it.
