4. Maintenance and Care

4.1 Cleaning the Display

To clean the display screen, gently wipe it with a soft, lint-free cloth. For stubborn marks, slightly dampen the cloth with water or a non-abrasive, display-safe cleaning solution. Avoid spraying liquids directly onto the screen or into the display's vents.
