8. Troubleshooting
- Device Not Powering On:
- Ensure the USB cable is securely connected to both the module and the power source.
- Verify that the +5V USB power source is functional (e.g., try charging a phone with it).
- Try a different USB cable or power source.
- No Indication Light: If the device has an indicator light and it's not on, follow the steps for "Device Not Powering On." If the power source is confirmed functional, the device may be faulty.
- Interference: If you suspect interference with other electronic devices, try relocating the Schumann Wave Generator or the affected devices.
