Common Problems and Solving Method

1. Soundbar not turning on: Please charge the battery.
2. Low battery reminder: Connect the charger immediately. Reduce playback volume to 50% if using while charging.
3. Cannot establish a connection after multiple attempts:
   • (1) Check if the soundbar is in Bluetooth search mode.
   • (2) If there are too many Bluetooth receivers nearby, it can interfere with the search process. Turn off other Bluetooth receivers.
   • (3) On your phone's Bluetooth settings, disconnect from the soundbar and try to establish a connection again.
4. Soundbar volume too low or distorted: Check the volume settings on your phone and adjust accordingly.
5. Signal dropping during music playback: Ensure the distance between your phone and the soundbar is within the effective range and check for any physical barriers.
6. Buttons unresponsive: Try using the player on your phone or another playback device.
7. Soundbar uncontrollable during use: Reset the soundbar using the appropriate tool. The hardware reset button is located inside the AUX connection.
