7. Troubleshooting
- No Sound/Microphone Not Detected:
- Ensure the receiver is fully and correctly plugged into your device's port.
- Verify that the microphones are powered on and successfully paired (green indicator light).
- Check if the microphone is muted.
- Confirm your recording application is set to use the external microphone.
- Ensure the device's volume is not set to zero.
- Poor Audio Quality/Excessive Noise:
- Ensure the microphone is positioned correctly, approximately 6-8 inches from the sound source.
- Avoid placing the microphone directly in front of strong air currents or wind.
- Check for obstructions between the microphone and receiver that might interfere with the wireless signal.
- Ensure the microphone is fully charged. Low battery can affect performance.
- Microphone Not Charging:
- Ensure the charging case is connected to a working power source.
- Verify that the microphones are correctly seated in the charging case.
- Check the USB-C charging cable for damage.
- Limited Wireless Range:
