Perform a top and bottom boresight adjustment to fix image focus issues that cannot be corrected by aligning
the projector to the screen and focusing the lens.
Caution! If not avoided, the following could result in minor or moderate injury.
•
This procedure must be performed by Christie qualified technicians.
Ensure that the projector is perpendicular to the screen before adjusting boresight.
Christie recommends completing a top and bottom boresight adjustment before adjusting the horizontal
boresight.
A boresight adjustment should only be made when the image cannot be focused uniformly on the screen by
aligning the projector to the screen and focusing the lens. When adjusting boresight, you must maintain the
boresight distance from the lens to the prism plane set by Christie. For example, when you move the top
screw outward, turn the bottom two boresight screws to maintain the overall distance.
Ensure that the boresight lockdown screws are adequately tightened. Not adequately tightening the boresight
screws can result in excessive onscreen image vibration. After adjusting boresight, evaluate the onscreen
image vibration and re-adjust if needed.
1. Remove the lens surround.
2. Display the DC2K Boresight test pattern.
3. Loosen the set screw (B).
