3. Installation Guidelines
particles in the environment of the projector. The manufacturer reserves the right to refuse repair if a projector has been subject to
wantful neglect, abandon or improper use.
Special Care for Laser Beams
Special care should be used when DLP projectors are used in the same room as performant laser equipment. Direct or indirect hitting
of a laser beam on to the lens can severely damage the Digital MicroMirror Devices™ in which case there is a loss of warranty
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 (49.2ft) (depending on the ambient light
conditions), with an aspect ratio of 4 to 3.
