NOTE:

Illustrations show the projector installed
using optional ceiling bracket.

This illustration is not drawn to scale.

L: Distance to screen
H: Height from the edge of screen to

center of lens

* This distance is especially recommend-

ed 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.

Aspect ratio 4 : 3
minimum

L (m) = (diagonal screen size in inches) x 0.0292 – 0.036

maximum

L (m) = (diagonal screen size in inches) x 0.0351 – 0.044

NOTE: Distances calculated with the above equations will include a slight error.

Installable Angle

Install the projector at an angle within the range shown below.

• Vertical direction

The projector

may be installed

at a vertical

angle of ±30°.

• Vertical direction

The projector may not be angled horizontally.
