GSBR-20 – FM Radio Setup & Reception Tips

The GSBR-20 includes a built-in FM tuner that allows you to listen to local radio stations. If you're having trouble accessing or maintaining a clear signal, follow these steps to improve performance.

Problem: FM Mode Not Activating

• Power on the speaker and press the rotary knob to cycle through modes until “FM” is selected.
• If the speaker doesn’t respond, restart it and try again.
• Make sure the AUX cable is connected - this functions as the FM antenna.

Problem: Poor Reception or Static

• Extend the AUX cable fully and position it away from metal surfaces or walls.
• Reposition the speaker to a higher or more open location.
• Avoid placing the speaker near other electronics that may cause interference.

Problem: No Stations Found

• Enter FM mode and long press the Play/Pause button to auto-scan available stations.
• Use the Next/Previous buttons to cycle through saved stations.
• If no stations are saved, try scanning again in a different location.

Additional Tips

• The FM frequency range supported is 87.5 - 108 MHz.
• Reception quality may vary depending on your location and surroundings.
• The AUX cable must be fully inserted and extended for best results.
