Tips for Installation
Unsuitable Installation
Do not install the projector in the following situations.
These installations may cause malfunction or damage
to the projector.
Poorly ventilated
• Allow adequate air circulation to prevent internal
heat build-up. Do not place the unit on surfaces
(rugs, blankets, etc.) or near materials (curtains,
draperies) that may block the ventilation holes.
When the internal heat builds up due to the block-up,
the temperature sensor will function with the
message "High temp.! Lamp off in 1 min." The
power will be turned off automatically after one
minute.

• Leave space of more than 30 cm (11 / inches)

around the unit.
• Be careful that the ventilation holes may inhale
tininess such as a piece of paper.
• If you put something in front of the front ventilation
holes, the exhaust may be inhaled into the projector
through the ventilation holes at the bottom, causing
the internal temperature to rise, which activates the
protection circuit. Install the projector so that the
exhaust is not blocked.
Highly heated and humid
• Avoid installing the unit in a location where the
temperature or humidity is very high, or temperature
is very low.
• To avoid moisture condensation, do not install the
unit in a location where the temperature may rise
rapidly.

Very dusty
Avoid installing the unit in a location where there is a
lot of dust; otherwise, the air filter will be obstructed.
The dust blocking the air through the filter may cause
raising the internal heat of the projector. Clean it up
periodically.
Notes on Installation
Carry out the followings.
No toppling of the unit
Avoid using as the unit topples over on its side. It may
cause malfunction.
