3. Loosen the vertical lock screw (A).
4. Extend the lens focus (B) completely.
5. To retract the lens, adjust the Focus knob. 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 10.
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 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.
10. Tighten the lock screw (A) and the lens mount stabilization screw (D) to maintain the
adjustments.
