9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Power adapter not connected properly or no power from outlet. | Ensure power adapter is securely plugged into both the device and a working electrical outlet. Test the outlet with another device. |
| Some LEDs are not lighting up. | This is normal for infrared LEDs (850nm) as they are not visible to the naked eye. | The 850nm infrared LEDs are designed to be invisible. You can test them by looking through a digital camera (e.g., phone camera) which can often detect infrared light. The 660nm red LEDs should be visible. |
| Device feels too warm. | Normal operation may generate some heat. Prolonged use or poor ventilation. | Ensure the device is not covered during use. If it becomes uncomfortably warm, discontinue use and allow it to cool down. Reduce session duration. |
