NOTE:
Illustrations show the projector installed
using optional ceiling mount 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) × 0.0302 – 0.035
maximum
L (m) = (diagonal screen size in inches) × 0.0358 – 0.035
Aspect ratio 16 : 9
minimum
L (m) = (diagonal screen size in inches) × 0.0330 – 0.041
maximum
L (m) = (diagonal screen size in inches) × 0.0391 – 0.040
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°.
Projection distance for 4:3 aspect ratio screen
• Horizontal direction
The projector may be installed at a horizontal angle of ±10°.
