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 rub the lens with abrasive materials.
