Card machines generally have an automatic lens shutter cover to protect the lens.

Please note the following points:

1. Please don't touch the lens with your hands after turning it on, and don't let foreign objects such as liquid and sand enter the gap around the lens.

2. In order to prevent water and other liquids from splashing on the lens, if there are fingerprints or waterlines on the lens, please wipe it with a lens-specific wiping cloth dipped in anhydrous alcohol.

3. When not in use, please store the camera in a dry and dusty environment, such as a constant humidity box.
