Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or low volume | Volume too low on speaker or source device; speaker not properly connected. | Increase volume on both the speaker and your connected device. Ensure Bluetooth is paired or AUX cable is fully inserted. |
| Cannot pair via Bluetooth | Speaker not in pairing mode; device Bluetooth off; too far from speaker. | Ensure speaker is in Bluetooth mode. Turn Bluetooth off and on again on your device. Move device closer to the speaker (within 10 meters). |
| Poor FM radio reception | Weak signal; no external antenna. | Plug a 3.5mm audio cable or USB cable into the AUX-in or USB port to act as an external antenna. Reposition the speaker for better signal. |
| Speaker starts at loud volume in FM mode | This is a known characteristic of some units. | Lower the volume immediately after switching to FM mode. The speaker has a last volume memory feature, but initial FM mode might default to a higher setting. |
| Cannot select folders on Micro SD/USB | Feature not supported. | The speaker does not support folder selection for Micro SD or USB playback. It will play all songs sequentially. |
| Cannot loop a single song from Micro SD/USB | Playback mode limitation. | To repeat a single song, ensure only that song is present on the Micro SD card or USB drive. The speaker typically loops all songs on the storage device. |
| Cannot connect to Bluetooth headsets | Speaker is a Bluetooth receiving device, not a transmitting device. | This speaker is designed to receive Bluetooth audio from devices like phones or tablets, not to transmit audio to Bluetooth headphones. |
| Voice prompts are too loud/annoying | Previous versions had voice prompts. | The upgraded version of this speaker has replaced voice prompts with soft tones for Bluetooth connection and added a max volume warning beep instead of a loud voice prompt. |
