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  • Computer Connection Issues: If your phone connects but your laptop/desktop cannot, this may be due to outdated or missing Bluetooth drivers.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.
  • Quality Assurance: Contact customer service for troubleshooting, repair, or replacement options if you encounter any issues.
