SAFETY INSTRUCTIONS
On re-packing
Save the original shipping carton and packing material; they will come in handy if
you ever have to ship your equipment. For maximum protection, re-pack 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.
1-6
5975069A BARCOVISION 708 200498
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.

INSTALLATION 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
INSTALLATION GUIDELINES
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.

INSTALLATION GUIDELINES
* 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 Viewing 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 BARCOVISION 708 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
* 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 BARCOVISION 708, equipped with HD145 lenses,
formulas are given in the next paragraph.
Abbreviations used on drawing and diagrams on next pages
B = Distance between ceiling 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 negative.)
CD = Total distance between projector and ceiling.
CD = A + B (When the result is negative, enlarge the distance between
ceiling 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 HD145 lenses (metric).
