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 may cause a fire.

Caution:

Do not use canned air, or the gases may leave a flammable residue.
