Before installation (continued)
Installation position
Decide the installation position on the wall or ceiling while referring to "Projection related dimension diagrams,"
"Projection distances," and "Mounting hole dimensions."
The following illustrations are examples of the projection lens surface of the main unit of the projector and the
projection surface positioned so that they are facing each other straight. The projection position and projection
screen size can be adjusted on the projector side in accordance with the projection surface position and range.

Projection distances (when the aspect ratio is 4:3)
The following shows the dimensional relationship between the projector and projection surface.
In addition, some dimension deviation may exist in the following table. Also, when keystone correction is
performed on the projector side, correction is made so that the projected image size becomes smaller than the
specified screen size.
