height (h), find the required distance between the top of the image area and the
wall plate (c).

(h), and (c), plus an additional 10 inches for the height of the wall plate plus the
cover.
If the ceiling height of your room (as noted in step 1) does not meet the
minimum ceiling height required for your board, you may need to select a
smaller image size or move the board to a lower position on the wall.
(10)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 of the wall plate.
(11)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 in the Installation Guide to install the projector.
