5. Troubleshooting
If you encounter issues with your Audio Array AM-W20, refer to the following common troubleshooting steps:

- Verify that there are no significant obstacles or sources of interference within the 50-meter range.
- For Android devices, confirm that the OTG function is enabled in your phone's settings.
- Poor Audio Quality / Disturbance / Shrieking Sound:
- Noise Cancellation: Ensure noise cancellation is activated (green light on TX). If recording in extremely noisy environments, some residual noise may still be present.
- Microphone Placement: Avoid placing the microphone too close to your mouth or directly under your chin. Optimal placement is typically 6-8 inches below the mouth.
- Recording Volume: If experiencing a shrieking sound, the input volume might be too high. Adjust the recording volume settings on your device if possible.
- Interference: Move away from other wireless devices or strong electromagnetic fields that might cause interference.
- Charging Issues:
- Ensure the USB-C charging cable is fully inserted into both the charging case and the power adapter.
- Try a different USB-C cable and power adapter to rule out faulty accessories.
- Check for any debris in the charging ports of the case or devices.
- No Sound Recording (Android):
- Enable OTG in your phone's settings.
- Use a third-party camera app like 'Open Camera' and ensure 'External mic' is selected as the audio source in its settings.
