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,

Only adjust vertical boresight 1/8 of a turn or less at one time to maintain optimal lens performance
