2. Installation Guidelines
air supply. Devices or structures to extract or shield contaminated air well away from the projector are a prerequisite, if this is not a
feasible solution then measures to relocate the projector to a clean air environment should be considered.
Only ever use the manufactures recommended cleaning kit which has been specifically designed for cleaning optical parts, never
use industrial strength cleaners on a projectors optics as these will degrade optical coatings and damage sensitive optoelectronic
components. Failure to take suitable precautions to protect the projector from the effects of persistent and prolonged air contami-
nants will culminate in extensive and irreversible ingrained optical damage. At this stage cleaning of the internal optical units will be
non-effective and impracticable. Damage of this nature is under no circumstances covered under the manufactures warranty and
may deem the warranty null and void. In such a case the client shall be held solely responsible for all costs incurred during any
repair. It is the clients responsibility to ensure at all times that the projector is protected from the harmful effects of hostile airborne
particles in the environment of the projector. The manufacture reserves the right to refuse repair if a projector has been subject to
wantful neglect, abandon or improper use.

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 projection 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 will '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 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. A high gain screen will provide a brighter picture but reduce the viewing angle.
What image size ? How big should the image be ?
The projector is designed for projecting an image size (video) from 1.00m (3.3ft) to 6.00m (19.7ft) with a aspect ratio of 5 to 4.

2.3 Configuration

Which configuration can be used ?

The projector can be installed to project images in four different configurations :
• Front/table
• Rear/table
• Front/ceiling
• Rear/ceiling
