5975248 BARCOVISION 701 MULTIMEDIA 090497

SAFETY INSTRUCTIONS

- To ensure the highest optical performance and resolution, the projection lenses are
specially treated with an anti-reflective coating, therefore, avoid touching the lens.
To remove dust on the lens, use a soft dry cloth. Do not use a damp cloth, detergent
solution, or thinner.

On repacking

Save the original shipping carton and packing material; they will come in handy if you
ever have to ship your equipment. For maximum 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 florescent 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 method

INSTAL L AT ION GU ID ELIN ES

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.

5975248 BARCOVISION 701 MULTIMEDIA 090797

INSTALLATION GUIDELINES

Screen width

* 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 701 MULTIMEDIA 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.

* 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 701 MULTIMEDIA, 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).

Optical lens focusing

The optical focusing procedure is
performed separately for each lens.
The appropriate CRT will be switched
on as the user proceeds through the
optical focusing adjustment se­quence.

Each lens has two focus adjust­ment points, one at the rear of the
lens and one at the front. The
center of the projected image is
focused by loosening the wing nut
at the rear end of the lens and
rotating the lens barrel until the
center of the image is clearly fo­cused. The corners of the pro­jected image are focused by loos­ening the wing nut at the front end
of the lens and rotating the lens
barrel until the corners of the image
are clearly focused. Repetition of
these adjustments may be neces­sary to optimize optical focusing.
Press ENTER key to continue.

Raster centering

The raster must be centered on the CRT screen surface of each tube, therefore,
it is necessary to look into the lenses.

Caution : To avoid eye discomfort while performing these adjustments, reduce the
contrast and gradually increase the brightness level until the raster becomes
visible behind the image.

Warning : In order to ensure maximum CRT longevity and to
avoid CRT damage, do not shift the raster outside the phos­phor area of the CRT.

Press ENTER to display the raster on

CRT projection angle adjustment

The projection angle of the red and blue CRT's is dependent on the desired size
of the projected image. If the centers of green, blue and red do not coincide, the
CRT projection angle must be adjusted. Never try to correct this misalignment with
the shift correction or the static convergence controls. These controls may only be
applied to correct small errors which cannot be corrected by the CRT angle
adjustment.

Ensure that the rasters are centered
on the CRT face.
