4. Setup and Initial Use
4.1 Charging the Device
Before first use, fully charge the main display unit using the provided USB cable and a compatible power adapter (not included). The charging indicator will show the charging status.
4.2 Connecting the Camera Probe

6. Maintenance
6.1 Cleaning the Camera Probe
After each use, especially in dirty or oily environments, gently wipe the camera probe and cable with a soft, damp cloth. For stubborn grime, a mild detergent can be used, followed by a clean, damp cloth. Ensure no liquid enters the main unit.
6.2 Cleaning the Display Screen
Use a soft, lint-free cloth to clean the display screen. Avoid abrasive materials or harsh chemicals that could scratch or damage the screen.
6.3 Storage
When not in use, store the device in its original packaging or a protective case in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the cable is neatly coiled to prevent kinks or damage.
