• Vertical direction
The projector may not be angled horizontally.

unit : mm (inch)
L: Distance to screen
H: 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 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.
