• 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 or you may damage it.
