Precautions on Installation
Avoid installing the projector in a location
subject to excessive dust
Do not use the projector while laying it on
its side or upside down
Do not tilt the projector when in use
Avoid tilting the projector more than ±5 degrees or installing it
other than on the floor and ceiling. Such installations may cause
malfunctions such as color irregularity or shortening of lamp life.
Do not cover the ventilation holes
(exhaust)
Do not cover the ventilation holes (exhaust) on the left side;
otherwise, internal heat may build up.
Do not install the projector on a deep-pile
carpet
If you install the projector on a deep-pile carpet, the ventilation
holes (intake) may be blocked, causing an internal heat build-up.
Precautions on Installation
For installation examples with projection distances, see the
supplied “Projection Distance Charts.”
Do not install the projector in the following situations. These
installations may cause malfunction or damage to the
projector.
Do not install the projector in an ill-
ventilated place
The projector is equipped with ventilation holes for intake and
those for exhaust on the front, left and right sides to prevent internal
heat build-up. Do not block these ventilation holes and allow
adequate air circulation at an installation location.
Do not place any object beside the
projector
If you put something beside the ventilation holes on the sides, the
exhaust may be inhaled into the projector through the ventilation
holes (intake), causing the internal temperature to rise and thereby
activating the protection circuit. Install the projector so that the
exhaust is not blocked.
Do not install the projector in a location
where temperature or humidity is very
high
Avoid installing the projector in a location
where temperature may rise or fall rapidly
Be careful of air-conditioning and heating in a room where the
projector is installed, as sudden changes in temperature may lead to
moisture condensation and cause damage to the projector.

Front projection screen for ceiling installation
The silver screen is recommended. You can get a
picture that is two to four times brighter than that of
the white screen.
Rear projection screen
The rear projection screen is recommended for a bright
and clear full-screen picture projection since the
sunlight has little effect on the screen.
Notes
• A moiré pattern may occur in accordance with the
pitch of the screen.
• Be sure to confirm the picture quality before
installation.
White screen
When viewers watch the projected picture in a wide
area, you can obtain a picture that appears equally
bright from all parts of the room using the white screen
for both floor and ceiling installations.
Tips on the Screen

not given in the table below, you can calculate the
screen height and width from the screen size (inches)
as follows.
Calculate at the conversion rate of 25.4 mm to the
inch.
