Cleaning the Projection Window
Clean the projection window periodically, or whenever you notice dust or smudges on the surface.
• To remove dust or smudges, gently wipe the projection window with lens-cleaning paper.
• To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the
projection window.
Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the
projector lamp may cause a fire.
Caution: Do not use canned air, or the gases may leave a flammable residue.
