Technical Features & Troubleshooting

Bluetooth Connectivity: If the Bluetooth indicator light is not flashing regularly or stays on continuously, there may be an issue with the PAM8403 audio power amplifier board. Contact customer service for resolution.
Computer Connection Issues: If your phone connects but your laptop/desktop cannot, this may be due to outdated or missing Bluetooth drivers. Uninstall and reinstall the latest driver version.
Sound Distortion: Distorted, choppy, or breaking sound at high volume may indicate insufficient power supply or amplifier-speaker mismatch, which could damage components.
Background Noise: Some noise is normal during signal amplification, but excessive background noise may indicate power supply issues or board problems.
