Adjusting the vertical boresight angle

Warning! Failure to comply with the following could result in serious injury.
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.
Caution! Failure to comply with the following could result in minor or moderate injury.
Only adjust vertical boresight 1/8 of a turn or less at one time to maintain optimal lens performance
(i.e. factory setup of absolute lens distance to the prism). It is critical that each turn of the cap
screws is tracked to ensure adjustments are accurate.
It is recommended that you complete a top and bottom boresight adjustment before adjusting the
horizontal boresight.
