Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Speaker does not turn on or charge. | Battery is completely drained (DOA). | Connect the speaker to a wall USB power adapter (not a power bank) and leave it to charge for at least one hour, even if no indicator light appears immediately. The battery may be too low to show an immediate response. |
| Cannot pair with Bluetooth device. | Speaker is not in pairing mode; device's Bluetooth is off; too far from speaker. | Ensure speaker is in pairing mode (flashing blue LED). Turn off and on your device's Bluetooth. Move device closer to speaker (within 49 feet). |
| No sound. | Volume too low; incorrect input mode; audio source issue. | Increase speaker and device volume. Check if the correct input mode (Bluetooth, AUX, SD, USB) is selected. Verify audio is playing from the source device. |
| TWS pairing fails. | Speakers are already connected to another device; TWS pairing not initiated correctly. | Disconnect both speakers from any Bluetooth devices. Ensure both speakers are the same model. Follow TWS pairing steps precisely. |
