Section 1: Introduction
3. Adjust the Focus to retract the lens using the down arrow on the Main: Lens menu. See Figure 2-40.
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, 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 2-41. To correct this problem, adjust the Horizontal Bore-
sight bolt to direct or aim the lens mount towards the LEFT to balance out the left/right edges. See
Figure 2-39.
b. If the right side of the image fails to come into focus then the image focuses behind the screen. To cor-
rect this problem, direct the lens mount towards the RIGHT by adjusting the Horizontal 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 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 2-39.
