How do I clean 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. Do not use glass cleaner or any harsh materials to clean the projection window and do not subject the projection window to any impacts; you may damage it.
