Lens Mount Horizontal Boresight - Christie CP2000-M Setup Manual

Section 3: Installation & Setup
5. Adjust both left and right horizontal adjusters by half the number of turns, in the opposite
direction of the vertical adjust (Figure 3-13). For example, if the vertical adjust capscrews was
turned 1/8 of a turn, the left and right horizontal capscrews should be turned 1/16 of a turn in the
opposite direction.
6. Check the screen. If the projected image is worse than before the adjustment was made turn the
vertical adjust capscrew 1/8 of turn clockwise. Ensure the left and right horizontal adjusters are
adjusted equally in the opposite direction to correct axial focus.
NOTE: 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. Always observe the screen after each adjustment. If necessary, continue to make adjustments until
both top and bottom are equally sharp. Remember to adjust left and right horizontal adjusters
in the opposite direction each time. This ensures the lens is in the same relative position.
8. When the top and bottom of the image are equally in focus lock the setscrew to hold that position.
Recheck the image.
9. If fine tuning is required, focus the image at the left and right sides. Refer to
Horizontal

Lens Mount Horizontal Boresight

Only adjust horizontal boresight 1/16 of a turn at a 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 capscrew is tracked to ensure adjustments
are accurate.
Horizontal boresight should only be adjusted if a large horizontal tilt to the screen is required.
1. When top/bottom boresight is complete, fine tune the image at the left and right sides of the screen.
2. Select an appropriate test pattern for boresight adjustments, via the CDP through the Test Patterns
menu. It is recommended to use the DC2K Framing test pattern.
3. Use a 5mm Allen™ key to loosen the setscrew for right boresight (Figure 3-13, B).
