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.
