8. After confirming your image size, use tape or a pencil to mark the distance (c) from the
top of the image area on the board to the bottom holes of the wall plate.
9. Align the line (horizontal) on the template sheet with the (c) mark, then align the
center line on the template sheet with the center of the image area. Follow the
instructions on page 30 to install the projector.
The tables on the following pages provide installation information for all supported image sizes. The
minimum ceiling height is based on an image 30 inches from the floor; if the image is lower, the minimum
ceiling height is reduced by the corresponding measurement.
Use the worksheets, the illustrations, and the information in the tables on the following pages to determine
the projection distance and placement of the wall plate. The recommended range for projection distance (a)
as shown on the following pages is 2.5 to 12.2 inches (62 to 311 mm).

Diagonal image size and mounting position

The numbers on the slider measure (b) are the same as the projection distance (a) when the diagonal image
size (S) is 75 inches or more. Because the installation position of the projector changes when (S) is less than 75
inches, the numbers for (a) and (b) differ.
