Maintenance
- Cleaning the Lens: After each use, especially in dirty or dusty environments, gently wipe the camera lens with a soft, lint-free cloth. For stubborn grime, a small amount of lens cleaning solution can be applied to the cloth. Avoid abrasive materials or harsh chemicals.
- Cable Care: The 16.5 ft (5m) semi-rigid cable should be coiled loosely for storage to prevent kinks or damage. Avoid sharp bends or excessive force when manipulating the cable.
- Waterproof Rating: The endoscope camera and cable are IP67 waterproof, allowing for use in damp or submerged conditions. After use in water, ensure the camera head and cable are thoroughly dried before storage. Do not submerge the USB connector or your connected device.
- Storage: Store the endoscope and its accessories in a clean, dry place away from extreme temperatures and direct sunlight.
