Gemini GSBR-20 Troubleshooting Guide 

The Gemini GSBR-20 is a compact, battery-powered Bluetooth soundbar with support for USB, microSD, FM radio, and AUX input. It features dual 2" metal drivers, bass radiators, and a rechargeable 3600mAh battery. This guide covers common issues and links to more detailed articles for specific problems.

1. Speaker Won’t Power On

• Make sure the speaker is fully charged. Connect the USB-C cable to a 5V/2A power source.
• Check the LED charge indicator. It should be red while charging and green when full.
• Press and hold the rotary knob to power on. If it doesn’t respond, try a different cable or outlet.
• Avoid using the speaker while charging for extended periods. Turn it off during charging to prevent interference.

2. No Sound

• Confirm the speaker is in the correct mode (Bluetooth, AUX, USB, etc.). Short press the rotary knob to cycle modes.
• Check volume levels on both the speaker and your connected device.
• Try a different audio source or cable to isolate the issue.

3. Bluetooth Connection Issues

• The speaker defaults to Bluetooth mode when powered on. The LED ring will flash during pairing.
• On your device, search for and select “GSBR-20”.
• If pairing fails, restart both devices and ensure no other device is connected.
• Keep within the 10-meter wireless range and avoid metal surfaces that may interfere.

4. USB or microSD Playback Not Working

• Ensure files are in MP3 format.
• Insert the USB or microSD card fully. Playback should start automatically.
• Use the Next/Previous buttons to navigate tracks.
• If playback doesn’t start, try a different media device or reformat the card.

5. FM Radio Reception Is Poor

• Enter FM mode using the rotary knob.
• Long press Play/Pause to auto-scan stations.
• Use the AUX cable as the FM antenna—make sure it’s fully inserted and extended.
• Reposition the speaker away from metal surfaces for better reception.

6. Speaker Shuts Off Unexpectedly

• Check battery level. Playback time varies by mode and volume.
• Recharge fully before retrying.
• Avoid using the speaker in high-heat environments or while charging for long periods.
