• 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 wipe the lens immediately after turning off the light source; otherwise, it could be
damaged. Do not use glass cleaner or any harsh materials to clean the lens and do not subject the
lens to any impacts; 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.
