L: Distance to screen
E: Height from the edge of screen to center of lens
NOTE:
Illustrations show the projector installed using optional ceiling bracket.
This illustration is not drawn to scale.
* This distance is especially recommended for ceiling-mounted use and other permanent installations.
NOTE:
Values shown are approximate.
The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
When the shortest projection distance is used, a small amount of distortion may occur in the image due to the zoom lens characteristics.
Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.

L (mm) = (diagonal screen size in inches)
x 0.0307 - 0.0310
L (mm) = (diagonal screen size in inches) x 0.0371 - 0.0290

L (mm) = (diagonal screen size in inches)
x 0.0335 - 0.0315
L (mm) = (diagonal screen size in inches) x 0.0405 - 0.0365
