2.8.3 Adjust Top/Bottom Boresight
When the horizontal boresight is complete, focus the image at the top
edge of the screen.
1. Loosen the
Vertical Hold Screw
. See
Figure 2-42
.
2. Extend the lens focus completely.
3. Adjust the
Focus
to retract the lens using the down arrow on the
Main: Lens
menu. 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, adjust the Vertical Boresight. If the entire
screen come into focus, skip to step 8.
4. 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 bal-
ance 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, direct the lens mount DOWN by adjust-
ing the
Vertical Boresight
accordingly.
5. When both sides appear equally blurry, adjust the
Offset
by clicking the up/down/left/right buttons on the
Main:
Lens
menu to re-center the image on the screen.
6. Repeat Steps 2 - 5 until the top and bottom of the screen are both well-focused.
7.
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.
8. Adjust the
Vertical Hold Screw
to lock the lens mount in place. Check boresight again. See
Figure 2-42
.
For more information on ILS and channel setups, refer to
Section Custom: Lens Menu, on page 3-26
.
2.8.4 Copy the Channel Settings To Another Channel
Once the basic image alignment for a channel is complete, you
can copy this setting between channels.
• From the
Custom: Lens
menu, use the drop-down menu to
select a particular channel and click
Copy
for the changes to
affect the selected channel. Repeat for every channel that
requires the same ILS values.
