Installation guidelines
Careful consideration of things 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
Max. ambient Temp. : 40 °C.
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 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. That appears as a less of 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.
