Table 3-3 lists the available LS-7 Series lens options and their associated throw ratios. 
Vertical and Horizontal 
Position
Proper placement of the projector relative to the screen will yield a rectangular, 
perfectly-centered image that completely fills the screen.
Ideally, the projector should be positioned perpendicular to the screen and in such a way 
that the lens center is aligned with either the top or bottom edge of the screen area, and 
centered horizontally. See Figure 3-3.
