Do not put any objects immediately in front of the lens
while the lamp is on.
The lens and the objects get hot and can cause fire or
breakdown.

It can lead to lamp breakage, fire, electric shock or other
trouble. It is best to wait for the fan to turn off before
turning the main power off.
Do not touch the exhaust vents and bottom plate,
which become hot.
Do not touch them or put other equipment in front of the
exhaust vents. The exhaust vents and bottom plate, when
heated, may cause injury or damage to other equipment.

affected by heat.
Do not look into the exhaust vents when projector is
operating.
Heat, dust, etc. may blow out of them and hurt your eyes.

If they are blocked, heat may be generated inside the
projector, causing deterioration in the projector quality and fire.
Do not use flammable solvents (benzene, thinner, etc.)
and flammable aerosols near the projector.
Flammable substances may ignite causing fire or
breakdown because the temperature inside the projector
rises very high while the lamp is illuminating.
Do not use the projector with condensation on it.
It can lead to breakdown or other failure.
