Adjust Left/Right Boresight; Adjust Top/Bottom Boresight - Christie Roadie HD+35K User Manual

Section 2: Installation and Setup

2.12.2 Adjust Left/Right Boresight

1. Adjust focus at the far left center edge of the image. If possible, reduce image size for easier image
analysis.
2. If the image appears well-focused on the left edge, but not on the right, then the boresight currently differs
from one side to the other. For example, the right side of the image is well-focused either in front of or
behind the screen surface rather than on it.
To determine where the right-side is focusing:
• Hold a piece of white paper approximately parallel to the screen surface at the right side (and as close to
the vertical center as possible), then move closer to the projector while watching the image on the paper.
• If focus on the paper improves, this indicates that the right side of the image is focusing in front of
the screen.
• If focus on the paper worsens, this indicates that the right side of the image is focusing behind the
screen.
GOAL: If the image comes into focus on both sides simultaneously, left/right boresight is fine. Skip to Step 6.
3. Adjust the horizontal boresight bolt
necessary to direct or "aim" the lens toward the side of the
image which focused too close to the lens. When both sides
appear equally blurry, re-focus on the left side of the screen.
4. Adjust horizontal offset to re-center the image on the screen.
5. Repeat Steps 3 and 4 until both sides of the image are well
focused.
6. Adjust the "hold" screw to lock in place, and check boresight
again.

2.12.3 Adjust Top/Bottom Boresight

1. When the left/right boresighting is complete, focus the image at the top edge of the screen.
2. If the bottom remains blurry while the top edge is focused, refer back to
Boresight, Step 2. However, use a paper at the bottom of the screen to determine whether the bottom of the
image is focused in front of the screen or behind the screen. If the bottom is well focused, skip to Step 6.
