Troubleshooting

No power / Device won't turn on:

Ensure the battery is charged. Connect the speaker to a power source using the USB charging cable and try again.

No sound:

Check the volume level on both the speaker and the connected device. Ensure the correct playback mode is selected. If using earphones, ensure they are fully plugged in.

Bluetooth pairing issues:

Make sure the speaker is in Bluetooth mode and discoverable. Ensure your device's Bluetooth is enabled and within range (10m). Try unpairing and re-pairing the device.

Poor FM radio reception:

Fully extend the telescopic antenna. Try moving the speaker to a different location to improve signal strength.

USB/TF card not playing:

Ensure the USB disk or TF card contains compatible audio files (MP3 format). Check that the card/disk is inserted correctly and the speaker is in the correct mode.

User Tips

• Charging Port: The speaker charges via a DC 5V port, which is typically a Micro USB connection. Ensure you use a compatible cable and power adapter for charging.
