Selected FAQ

Q:
How and when should I clean the lens?
A:
Clean the projector's lens periodically, or whenever you notice dust or smudges on the surface.
  • To remove dust or smudges, gently wipe the lens with lens-cleaning paper.


  • To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the lens. Do not spray any liquid directly on the lens.
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 glass cleaner to clean the lens, or you may damage it. Do not use canned air, or the gases may leave a residue. Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.
