Definitions of the Abbreviation on drawings
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 feed) 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 = 140.5 mm.)
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.
