3. 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 projector is designed for projecting an image size : min 1.00m (3.3ft) to max 15 m (49.21ft) (depending on the ambient light
conditions), with the native aspect ratio of the projector.
3.2 Air flow guidelines
What are the air flow guidelines ?
The Air Outlet on the side of the Projector can reach high temperatures due to the High Light Output Range of the lamp.

Air inlet obstruction
CAUTION: Never obstruct the cooling air inlet at the bottom of the projector.
Always insure there is enough space between the bottom of the projector and the floor, to allow air to enter
the projector.
WARNING: Do not touch this Air Outlet when the projector is switched on.
