Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power adapter not connected or faulty. | Ensure the power adapter is securely plugged into the speaker and a working power outlet. Check the power adapter for damage. |
| Cannot pair via Bluetooth | Speaker is not in pairing mode or too far from the device. | Ensure the speaker is powered on. Move your device closer to the speaker. If already paired, try unpairing and re-pairing. Long press the TWS/Reset button for 3 seconds to reset Bluetooth. |
| No sound | Volume too low, incorrect input, or speaker cable issue. | Increase volume on both the speaker and your connected device. Verify the speaker cable connection between active and passive speakers is correct and secure. |
