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.

Projection size
(diagonal)
Height from the edge of screen
to centre of lens (H)
Projection distance (L)
Min (wide) Max (telephoto)
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 0.0296 – 0.039
maximum L (m) = (diagonal screen size in inches) x 0.0358 – 0.047
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.
