7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery. | Charge the device fully using the provided Type-C cable. |
| Image is blurry or unclear. | Dirty lens; incorrect focal distance. | Clean the camera lens. Ensure the object is within the specified focal range for the active lens (front: 1.18-5.9in; side: 0.78-3.93in). |
| No image on screen. | Cable not properly connected; camera malfunction. | Ensure the camera cable is securely connected to the monitor unit. If the issue persists, contact customer support. |
| LED lights are not working or too dim/bright. | Brightness setting; low battery. | Adjust the LED brightness using the light adjustment button. Charge the device if the battery is low. |
| Cannot save photos/videos. | TF card full or not inserted correctly; card error. | Check if the 32GB TF card is properly inserted. Delete unnecessary files to free up space or try formatting the card (this will erase all data). |
| Cable is difficult to maneuver. | Complex bends; insufficient rigidity for application. | The semi-rigid cable is designed to hold its shape. For very tight or long bends, gentle manipulation and patience are required. Consider using a guide wire if applicable to your inspection scenario. |
