Illumination
To obtain a clear picture, the screen should not be exposed to illumination
or sunlight directly from the front.
•Ceiling mounted spot lighting is recommended. Use a construction over
light scattering illumination such as fluorescent lamps.
•Cover the windows that face the screen with opaque draperies.
•It is desirable to install the projector in a room whose floor and walls are
of reflecting material, it would be desirable to change to a dark carpet and
wall paper.
Caution
Take care not to touch portions of the projector other than those indicated
in this manual because dangerous high voltages are present. To change the
polarity, first turn the MAIN POWER switch off.

Installation Procedures
This projector is adjusted at the factory for projection
on a 100-inch front projection type screen when the
projector is installed on the floor/desk. If you install
the projector under other conditions, modifications of
some parts in the projector are required. Therefore,
installation procedures vary depending on the screen
size, installation method and type of screen.
