Section 2: Installation and Setup

2.9.3 Adjust Top/Bottom Boresight

1. When the horizontal boresight is complete, focus the image at the top edge of the screen.
2. Loosen the Vertical Hold Screw.
3. Extend the lens focus completely.
4. Adjust the Focus knob to retract the lens. Watch
the image at the top edge of the screen until it
comes into focus. If the image appears well-
focused on the top edge but not on the bottom,
we need to determine if the bottom edge focuses
in front of or behind the screen. If the entire
screen come into focus, skip to step 8.
5. Continue retracting the lens.
a. If the bottom edge of the image comes into focus before the lens
is completely retracted, then the image focuses in front of the
screen. To correct this problem, adjust the Vertical Boresight
Bolt 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 fails to come into focus then the
image focuses behind the screen.To correct this problem, adjust
the Vertical Boresight Bolt to direct or aim the lens mount
DOWN towards the bottom of the screen.
6. When both sides appear equally blurry, adjust the horizontal and/or
vertical Offset to re-center the image on the screen.
7. Repeat Steps 2 - 5 until the top and bottom of the screen are both
well-focused.
8. Refocus: Although all sides of the image should now be in focus, the
center of the image may be slightly blurry at this point. Re-focus the center of the image. The goal is for
good focus at the center and on all sides.
9. Adjust the Vertical Hold Screw to lock the lens mount in place and check boresight again.
