• Never touch the projector mirror or Lens directly by hand.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface.
• Use a canister of compressed air to remove dust.
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and
gently wipe the lens surface.
Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as
alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with rubber
