- To keep the cabinet looking brand-new, periodically clean it with a
soft cloth. Stubborn stains may be removed with a cloth lightly
dampenedwith milddetergentsolution. Neverusestrongsolvents,
such as thinner or benzine, or abrasive cleaners, since these will
damage the cabinet.
- To ensure the highest optical performance and resolution, the
projection lenses are specially treated with an anti-reflective coat-
ing,therefore,avoidtouching the lens. Toremoveduston the lens,
usea soft drycloth. Do notuse a dampcloth, detergent solution, or
thinner.
On repacking
Save the original shipping carton and packing material; they will
comeinhandyifyoueverhavetoshipyourequipment.Formaximum
protection, repack your set as it was originally packed at the factory.
On illumination
Inordertoobtainthebestqualityfortheprojectedimage,itisessential
that the ambient light which is allowed to fall on the screen be kept to
an absolute minimum.
Wheninstalling theprojectorandscreen,caremustbetaken toavoid
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
andwalls ofthe room in which theprojector isto beinstalled 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.

3INSTALLATION GUIDELINES
Installation guidelines
Careful consideration of things such as image size, ambient light
level,projector placement andtype of screento use arecritical 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
sunlightandthelightfixturesintheroom. Theamountofambientlight
willdetermine howbright theimage 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
systeminaroomwhosewallsandfloorareofnon-reflectingmaterial.
The use of recessed ceiling lights and a method of dimming those
lightstoanacceptablelevelisalsoimportant. Toomuchambientlight
results in a ‘wash out’ of the projected image. This appears as less
contrast between the darkest and lightest parts of the image. With
biggerscreens,the‘washout’becomesmoreimportant. Asageneral
rule,darken the room to thepoint wherethere is justsufficient lightto
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. Thoseusedfor frontprojectedimages andthosefor 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
projectedtowardthem. The‘GAIN’ofascreenisthetermused. Front
andrearscreens arebothrated intermsof gain. Thegainof 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
betweenhigherandlowergainscreensislargelyamatterofpersonal
preference and another consideration called the Viewing angle.
In considering the type of screen to choose, determine where the
viewerswillbelocatedandgoforthehighestgainscreen possible. A
highgainscreenwillprovidea brighter picture butreducetheviewing
angle.
For more information about screens, contact your local screen
supplier.
* What image size? How big should the image be?
TheBARCODATA708isdesignedforprojectinganimagewidthfrom
1.4m (4.6') to 7m (23') with an aspect ratio of 4 to 3. It leaves the
BARCOfactory,adjustedasaceilingfrontprojectorforascreenwidth

* 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 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
betweenceilingandtopofthescreen,mountscreenlower,untilCD
becomes zero or positive)
SW = Screen width.
PD = Perpendicular distance between screen and projector.

Access to controls
Opening procedure :
During the projector set up and installation it is neces-
sary to open the top cover.
To gain access, procede as follow :
*Turn both lock screws with a screwdriver or a coin
counter clockwise.
* Lift up and pivot the top cover.
* Support the top cover with the hand, no support is
incorporated.
During some installations it will become handy to
remove the top cover totally.
Therefore,
- pivote the top cover ± 60°
-pushthetopcover to thefrontsideofthe projector
until it jumps out of its hings.
- Turn the top cover till 90° and lift it up.
Re-install the cover :
Hook the top cover into the cabinet hinges. Pivot the top cover 30°
and pull it backwards until it fits in the hinges. Close the cover and
secure the lock screws by turning clockwise with a screwdriver or
coin.

After scan inversion, close the chassis and close the top cover.
Reconnect the power cord to the wall outlet.
Note
Switching over from floor to ceiling or vice versa requires a complete
readjustment of picture geometry and convergence.
