Adjusting vertical boresight

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.
Make sure 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.
Make sure the boresight lockdown screws are adequately tightened. Inadequately tightening the
boresight screws can result in excessive on-screen image vibration. After adjusting boresight, evaluate
the on-screen 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 in the image below).
4. Turn the vertical cap screw (A in the image in step 3) 1/8 of a turn counter-clockwise.
Only adjust vertical boresight 1/8 of a turn or less at one time to maintain optimal lens
performance (factory setup of absolute lens distance to the prism). You must count each turn
of the cap screws to ensure accurate adjustment.
