Screen width
B = Distance between ceiling and top of the screen or
between floor and bottom of the screen.
A = Correction value, distance between bottom side of
projector (without feet) and middle of the lens. Value to be
subtracted from B to obtain the correct installation position. (A
value is a constant value for all screen widths and type of
lenses, A = 124.1 mm or 4.89 inch)
CD = Total distance between projector and ceiling or projector
and floor.
SW = Screen width.
SH = Screen height (image height).
PD = Projector Distance, distance between screen and
projector.
Lens type selection.
a) Determine the required screen width.
b) Determine the approximate position of the projector in the projection
room with regard to the screen and measure the
projector-screen distance (PD).
c) Use the lens formulas in appendix B to find the best corresponding
PD with regard to the measured projector-screen distance for the
required screen width.
The desired lens is determined (the order number is given in the tabel
in the same appendix B). Start the installation procedure for the
projector as described in the manual.

Definitions of the Abbreviation on drawings
* Where to install the projector?
* 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 (video) from
1.00m (3.3ft) to 6.00m (19.7ft) with a aspect ratio of 5 to 4.
