Be sure to unplug the power cord before cleaning the

The cabinet as well as the operation panel is made of
plastic. Avoid using benzene or thinner, as these can
damage the finish on the cabinet.

• 

Do not use volatile agents such as insecticides on the
projector.
Do not attach rubber or plastic items on the projector for long time.
The effects of some of the agents in the plastic may cause damage to the quality or finish
of the projector.

 

• 

Wipe off dirt gently with a soft flannel cloth.

 

• 

When the dirt is hard to remove, soak a cloth in a
neutral detergent diluted with 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.
