5. Operating Instructions
The RELIFE MC3 Pro is designed for ease of use, particularly with its one-second auto-focus feature.
5.1 Powering On and Initial View
- Ensure all connections (power, display/PC) are secure.

5.2 Auto Focus Functionality
- The MC3 Pro features a one-second auto-focus system. This means the camera will automatically adjust its focus to provide a clear image without manual intervention.
- When you move the workpiece or change tools under the microscope, the camera's lens will automatically track and lock onto the optimal focus point, instantly displaying a clear image. This significantly reduces waiting time and the need for constant adjustments.
- This feature is particularly beneficial for two-handed operations such as soldering or chip removal, allowing you to maintain a clear view and seamless workflow.

- The camera supports both timed shooting and real-time shooting for image capture.
- Video recording is available at 1920*1080 resolution at either 30fps or 60fps.

Proper maintenance ensures the longevity and optimal performance of your RELIFE MC3 Pro camera.
- Cleaning the Lens: Use a soft, lint-free cloth specifically designed for optical lenses to gently clean the camera lens. Avoid using abrasive materials or harsh chemicals.
- Cleaning the Body: Wipe the camera body with a soft, dry cloth. If necessary, a slightly damp cloth can be used, but ensure no moisture enters the ports or internal components.
- Storage: When not in use, store the camera in a clean, dry environment, away from direct sunlight, extreme temperatures, and excessive dust.
