protection, repack your set as it was originally packed at the factory.
On illumination
In order to obtain the best quality for the projected image, it is essential
that the ambient light which is allowed to fall on the screen be kept
to an absolute minimum.
When installing the projector and screen, care must be taken to avoid
exposure to ambient light directly on the screen. Avoid adverse
illumination on the screen from direct sunlight or fluorescent lighting
fixtures.
The use of controlled ambient lighting, such as incandescent spot light
or a dimmer, is recommended for proper room illumination. Where
possible, care should also be taken to ensure that the floors and walls
of the room in which the projector is to be installed are non-reflecting,
dark surfaces. Brighter surfaces will tend to reflect and diffuse the
ambient light and hence reduce the contrast of the projected image
on the screen.
CAUTION FIRE HAZARD
WARNING: DO NOT PLACE FLAMMABLE OR
COMBUSTIBLE MATERIALS NEAR PROJECTOR !

3INSTALLATION GUIDELINES
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.
* Which screen type?
There are two major categories of screens used for projection
equipment. Those used for front projected images and those for rear
projection applications.
Screens are rated by how much light they reflect (or transmit in the
case of rear projection systems) given a determined amount of light
projected toward them. The GAIN of a screen is the term used. Front
and rear screens are both rated in terms of gain. The gain of screens
range from a white matte screen with a gain of 1 (x1) to a brushed
aluminized screen with a gain of 10 (x10) or more. The choice
between higher and lower gain screens is largely a matter of
personal preference and another consideration called the iewing
angle.
In considering the type of screen to choose, determine where the
viewers will be located and go for the highest gain screen possible.
A high gain screen will provide a brighter picture but reduce the
viewing angle.
For more information about screens, contact your local screen
supplier.
* What image size? How big should the image
be?
The projector is designed for projecting an image width from 1.4m
(4.6') to 7m (23') with an aspect ratio of 4 to 3. It leaves the BARCO
factory, adjusted as a ceiling front projector for a screen width of
2.4m. Changing the image size from the factory preset requires a
realignment of the projector.

Installation Guidelines
3-2 5976026A BARCO ISION 708 200499
* Where to install the projector?
To indicate a correct installation position it is necessary to know the
distance :
- projector - ceiling
- projector - screen
To find this correct position for the projector, equipped with TAC4
lenses, formulas are given in the next paragraph.
Abbreviations used on drawin and dia rams on next pa es
B = Distance between ceilin and top of the screen.
A = Correction Value, extra value to be added to B to obtain the
correct installation position. (In some cases the A value can be
ne ative.)
CD = Total distance between projector and ceilin .
CD = A + B (When the result is ne ative, enlar e the distance
between ceilin and top of the screen, mount screen lower, until
CD becomes zero or positive)
SW = Screen width.
PD = Perpendicular distance between screen and projector.
Formulas for Projector to screen distance and correction value A with
regard to the screen width for TAC4 lenses (metric).
Formulas (metric)
PD[m] = 1.2642 x SW[m] + 0.2156
A[cm] = 12 x SW[m] - 22.88
Formulas for Projector to screen distance and correction value A with
regard to the screen width for TAC4 lenses (inch).
Formulas (inch)
PD = 1.2642 x SW + 8.48
A = 0.12 x SW - 9
* How to install the projector?
Ceiling mount or table mount?
To install the projector, apply always the BARCO kits which are
specially designed for this function.
BARCO ceilin support.
Always use the BARCO ceiling support to attach your projector to
the ceiling. (BARCO order number : R9827990)
