The cabinet as well as the operation panel is made of

 Wipe off dirt gently with a soft flannel
cloth.

water, wring the cloth well and then wipe
the projector.
Strong cleaning detergents may
discolour, warp or damage the coating on
the projector.
Make sure to test on a small, inconspicuous area on the projector before using.

• 

Use a commercially available blower or lens cleaning
paper (for glasses and camera lenses) for cleaning the
lens. Do not use any liquid type-cleaning agents, as they
may wear off the coating film on the surface of the lens.

As the surface of the lens can easily get damaged, be
sure not to scrape or hit the lens.

• 

Use a vacuum cleaner to clean dust from the exhaust
vent and the intake vent.
