5. Maintenance
- Cleaning the Probe: The camera probe is IP67 waterproof. After use, especially in dirty or wet environments, gently clean the probe with a damp cloth or rinse it under water. Ensure it is dry before storage. Do not submerge the main handle unit.
- Lens Care: The borescope features a sapphire lens. To maintain clear image quality, wipe the lens gently with a soft, lint-free cloth. Avoid abrasive materials that could scratch the lens.
- Battery Replacement: The borescope unit has a replaceable battery. If battery life significantly diminishes, consult the manufacturer for replacement options or instructions.
- Camera Tube Replacement: The camera tube is designed to be replaceable. If the probe becomes damaged, a replacement tube can be installed. Refer to the manufacturer's guidelines for proper replacement procedures.
- Storage: Store the borescope and its accessories in the provided hard carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.

6. Troubleshooting
- No Image on Screen:
- Ensure the borescope unit is powered on and fully charged.
- Verify the connection cable between the borescope and your smartphone/tablet is securely plugged in.
- Check if your smartphone/tablet is compatible and properly configured for USB camera input.
- Poor Image Quality:
- Adjust the brightness of the LED lights on the probe.
- Clean the camera lens if it appears dirty or smudged.
- Ensure the probe is not too close or too far from the object being inspected.
- Device Shuts Down Automatically:
- This is likely due to the high-temperature protection feature. Allow the probe to cool down before resuming operation. Avoid using the device in environments exceeding 90°C for extended periods.
- Probe Articulation Not Responding:
- Check for any obstructions preventing the probe from moving freely.
- Ensure the joystick is not stuck and moves smoothly.
- If the issue persists, contact customer support.
