Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Speaker does not power on. | Low battery or power issue. | Ensure the speaker is fully charged. Connect to power and try again. If the unit does not power on even when plugged in, there might be an internal battery management system (BMS) issue. For advanced users, a top review suggests soldering jumper leads from the 12VDC input to the battery connection posts if the battery is removed and the unit is used solely plugged in. However, this should only be attempted by qualified individuals and voids warranty. |
| No sound or low volume. | Volume too low, incorrect input mode, or device not connected. | Increase speaker and device volume. Press the 'M' button to cycle through input modes (Bluetooth, AUX, TF Card). Ensure Bluetooth is properly paired or AUX cable is securely connected. |
| Bluetooth connection unstable. | Device too far, interference, or pairing issue. | Move the device closer to the speaker (within 10 meters/33 feet). Avoid obstacles. Disconnect and re-pair the Bluetooth connection. Turn off other Bluetooth devices to reduce interference. |
| Distorted sound. | Volume too high, audio source quality, or speaker placement. | Reduce volume on both the speaker and the connected device. Try a different audio source. Adjust speaker placement; sometimes placing it in a corner or near a wall can enhance bass but may cause distortion if too close. |
