Use a soft, lint-free cloth to wipe the surface gently. For fingerprints or visible smudges, clean using two microfiber cloths:
1. Lightly dampen the first cloth with a mixture of mild detergent and water, then wipe the screen gently from left to right.
2. Use the second cloth with clean water to remove any remaining foam, then allow the screen to air-dry or gently wipe off excess moisture.
Do not use acetone, benzene, alcohol, or any other organic solvents, as they may cause permanent damage to the screen.
1. Ensure the floor surface is level to avoid tilting or jamming.
2. Fully retract the screen when not in use to reduce dust buildup and protect the structure.
3. Make sure the area above the screen is clear of any obstructions to prevent operational issues.
Lightly brush off surface dust using the included cleaning brush as needed. Perform a mild cleaning every 1–2 months to maintain optimal image quality.
