Adjusting Horizontal Boresight - Christie CP2208 User Manual

turn, the left and right horizontal cap screws should be turned 1/16 of a turn in the opposite
direction.
6. Check the screen each time an adjustment is made. If the quality of the projected image has
degraded, turn the vertical adjust cap screw 1/8 of turn clockwise. Ensure the left and right
horizontal adjusters are adjusted equally in the opposite direction to correct axial focus. The 1/
8 of a turn is a suggestion only and can be less if needed; however, it should never be
exceeded. Always compensate both left and right horizontal adjustments according to the
vertical adjustment.
7. Check the image after each adjustment. Continue to make adjustments until both top and
bottom are equally sharp. To make sure the lens is in the same relative position, adjust the left
and right horizontal adjusters in the opposite direction at the same time.
8. When the top and bottom of the image are equally in focus lock the set screw to hold it in
position. Recheck the image.
9. If additional adjustment is required, see
10. Replace the lens surround.

Adjusting horizontal boresight

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 horizontal 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.
Typically, horizontal boresight does not require adjustment. It should only be adjusted if a large
horizontal angular offset to the screen is required.
