Never rub or tap the lens with a hard object as
the lens surface is fragile.
Lens and main unit cleaning
Cleaning the main unit
• Pull out the power cord before cleaning.
• Use a soft cloth to wipe off stains from the
surface.
• To remove difficult stains, use a soft cloth
slightly moistened with a weak solution of
synthetic detergent and water, and finish with
a soft, dry cloth.
Replacing the intake, exhaust fans and air filter
To maintain the efficiency of the projector, replace the intake and exhaust
fans about every two to three years.
Ask the dealer for the replacement.

ask the dealer to carry out the maintenance
such as cleaning.
