Selected FAQ

How and when should I clean the lens?
Clean the projector's lens and interactive module's receiver window periodically, or whenever you notice dust or smudges on either surface.

  • To remove dust or smudges, gently wipe the lens or receiver window with lens-cleaning paper.

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