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.

Ensure that the projector is perpendicular to the screen before adjusting boresight.

Christie recommends that you complete 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. Inadequately 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).

4. Turn the vertical cap screw (A) 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). It is critical that you count

each turn of the cap screws to ensure accurate adjustment.
