Section 2: Installation & Setup
1. The Horizontal Hold Screw acts as counter-resistance to hold the lens mount in place once set. Before
adjusting the boresight, loosen the Horizontal Hold Screw. See Figure 2-24.
2. Extend the lens focus completely.
3. Adjust the Focus to retract the lens using the counter-clockwise button on the ILS screen (Figure 2-25).
Watch the image at the left edge of the screen until it comes into focus. If the image appears well-focused
on the left edge but not on the right, we need to determine if the right side focuses in front of or behind the
screen. If the entire screen come into focus, skip to step 7.
4. Continue retracting the lens.
a. If the right side of the image comes into focus before the
lens is completely retracted, then the image focuses in
front of the screen. See Figure 2-26. To correct this
problem, adjust the Horizontal Boresight Bolt to direct
or aim the lens mount towards the LEFT to balance out
the left/right edges. See Figure 2-24.
b. If the right side of the image fails to come into focus
then the image focuses behind the screen. To correct this
problem, direct the lens mount to the RIGHT by adjust-
ing the Horizontal Boresight Bolt accordingly.
5. When both sides appear equally blurry, adjust the Offset by
clicking the up/down/left/right buttons on the ILS menu to
re-center the image on the screen.
6. Repeat Steps 1 - 5 until both sides of the image are well focused.
7. Adjust the Horizontal Hold Screw to lock adjustments in place. Check boresight again. See Figure 2-24.
