4. Setup
- Charge the Device: Before first use, fully charge the endoscope camera using the provided USB charging cable. Connect the USB cable to the Type-C charging port on the side of the main unit and plug the other end into a standard USB power adapter (not included). The charging indicator will show the charging status.
- Attach the Semi-Rigid Cable: Align the connector of the semi-rigid cable with the port on the top of the main unit. Gently push and twist clockwise to secure the connection.
- Attach Accessories (Optional): If needed, screw the hook, magnet, or side mirror onto the threaded tip of the camera probe. Ensure they are securely fastened to prevent detachment during inspection.
5. Operating Instructions
- Power On/Off: Press and hold the power button (usually located on the front or side of the main unit) for a few seconds to turn the device on or off. The LCD screen will illuminate.
- Adjust LED Lights: Use the dedicated LED adjustment buttons (often marked with light bulb icons or '+' and '-' symbols) on the handle to increase or decrease the brightness of the camera's LED lights. There are typically multiple brightness levels.
- Image Rotation: Press the 180° image rotation button to flip the image on the screen. This is useful when navigating in confined spaces where the camera orientation might be inverted.
- Zoom Function: If available, use the zoom buttons to magnify the image on the screen for closer inspection of details.
- Navigate the Cable: Carefully guide the semi-rigid cable into the area you wish to inspect. The cable's flexibility allows it to bend around corners, while its rigidity helps in pushing it through longer distances.
- Optimal Focal Range: The camera has a specific focal range (0.78 to 3.94 inches / 20 to 100mm). For the clearest image, position the camera within this distance from the object of interest.

6. Maintenance
- Cleaning the Camera Lens: After each use, especially in dirty or wet environments, gently wipe the camera lens with a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying. Do not use abrasive cleaners or solvents.
- Cleaning the Cable: Wipe down the semi-rigid cable with a damp cloth to remove any debris or moisture. Ensure the cable is dry before coiling and storing.
- Storage: Store the endoscope camera and its accessories in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the cable is not kinked or bent sharply during storage.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. If storing for an extended period, charge the battery to approximately 50% every few months.
- Waterproof Integrity: While the camera probe is IP67 waterproof, avoid prolonged submersion beyond specified limits and ensure the Type-C charging port cover is securely closed when operating in wet conditions.
