7. Operating Instructions
7.1 Basic Inspection
Once powered on, the device will display a live feed from the probe camera.
- Carefully insert the flexible probe into the area you wish to inspect.
- Use the Rotate Wheel (refer to Figure 2) to articulate the probe tip 180° in two directions, allowing you to navigate around obstacles and view different angles.
- Observe the live feed on the 4.3" IPS display.
7.2 Adjusting LED Lights
The probe is equipped with 10 adjustable LED lights to illuminate dark inspection areas. There are 3 adjustable brightness levels.
- Use the dedicated LED control button (refer to Figure 2) to cycle through the brightness levels or turn the lights off.
7.3 Capturing Photos and Videos
The borescope can capture high-definition photos and videos (1920x1080P) directly to the installed 16GB Micro-SD card.
- To take a photo: Press the Photo/Video Button once to capture an image.

8. Maintenance
8.1 Cleaning the Probe and Lens
The probe is IP67 waterproof, but proper cleaning is essential for longevity and clear imaging.
- After each use, especially in wet or dirty environments, gently wipe the probe and lens with a soft, dry cloth.
- If the lens has water stains, ensure they are dried completely before storage to prevent mineral buildup or fogging.
- Do not use abrasive cleaners or solvents on the lens or probe.
8.2 Storage
- Store the borescope and its accessories in the provided carrying case to protect them from dust, impacts, and environmental damage.
- Keep the device in a cool, dry place away from direct sunlight.
- Ensure the battery is partially charged (around 50%) if storing for extended periods to prolong battery life.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery. | Charge the battery fully. |
| No image on screen. | Probe not connected properly. | Ensure the probe is securely attached. |
| Image is blurry. | Lens is dirty or focal distance is incorrect. | Clean the lens. Ensure the object is within the 2-10cm focal range. |
| Device shuts down unexpectedly. | High temperature protection activated. | Allow the probe to cool down. Avoid using in environments exceeding 90°C for prolonged periods. |
| Cannot save photos/videos. | Micro-SD card full or not inserted correctly. | Check if the 16GB Micro-SD card is properly inserted. Delete old files or format the card (backup important data first). |
10. User Tips
- For optimal image clarity, ensure the area being inspected is well-lit using the adjustable LED lights.
- Practice articulating the probe in an open space before inserting it into confined areas to get a feel for the controls.
- When inspecting engines or other machinery, be mindful of moving parts and hot surfaces.
- Regularly back up important inspection footage from the Micro-SD card to prevent data loss.
