Watch the image at the top edge of the screen until it comes into focus. If the entire screen is
in focus, proceed to step 8.
6. Continue retracting the lens.
a) If the bottom edge of the image comes into focus before the lens is completely
retracted, adjust the vertical boresight bolt (C) to direct or aim the lens mount up
towards the top of the screen to balance out the top/bottom edges.
b) If the top edge of the image is not in focus, adjust the vertical boresight bolt (C) to
direct or aim the lens mount toward the bottom of the screen
7. When both sides appear equally blurry, adjust the horizontal and/or vertical offset to re-
center the image on the screen.
8. Repeat Steps 2 to 7 until the top and bottom of the screen are both well-focused.
9. Re-focus the center of the image. The goal is for good focus at the center and on all sides.

adjustments.
