Install The Optional Wide Converter Lens; Install The Lamp - Christie CP4230 User Manual

Section 2: Installation and Setup
4. Adjust the location of the anamorphic lens so that the image does not shift left or right with the anamorphic
lens in and out.
5. Adjust the location of the anamorphic lens so the image passes through the center as much as possible
without vignetting, reducing side or corner brightness, especially in wide angle projection.
6. Remove the anamorphic lens and turn the Focus knob to re-focus the primary lens. The goal is for good
focus at the center and on all sides.
7. Re-install the anamorphic lens and check the focus.
8. If center-to-edge horizontal focus in the image needs improvement, rotate the focus barrel.
