Installation guidelines
Careful consideration of things such as image size, ambient light level, projector placement
and type of screen to use are critical to the optimum use of the projection system.
* Environment
Do not install the projection system in a site near heat sources such as radiators or
air ducts, or in a place subject to direct sunlight, excessive dust or humidity. Be
aware that room heat rises to the ceiling; check that the temperature near the
installation site is not excessive.
* What about ambient light ?
The ambient light level of any room is made up of direct or indirect sunlight and the
light fixtures in the room. The amount of ambient light will determine how bright the
image will appear. So, avoid direct light on the screen.
Windows that face the screen should be covered by opaque drapery while the set is
being viewed. It is desirable to install the projecting system in a room whose walls and
floor are of non-reflecting material. The use of recessed ceiling lights and a method
of dimming those lights to an acceptable level is also important. Too much ambient
light results in a 'wash out' of the projected image. This appears as less contrast
between the darkest and lightest parts of the image. With bigger screens, the 'wash
out' becomes more important. As a general rule, darken the room to the point where
there is just sufficient light to read or write comfortably. Spot lighting is desirable for
illuminating small areas so that interference with the screen is minimal.
