Offset And Boresight Alignment; Adjust Offset - Christie Solaria CP2220 User Manual

A.2 Offset and Boresight Alignment
The following instructions explain how to adjust the offset and boresight alignment using the ILS. Projectors
without the ILS should refer to
and consistently good focus in all areas of the screen, a primary lens must be installed and its lens mount
precisely adjusted in relation to internal optics as described below. If desired, an auxiliary lens can then be
added to widen images for scope cinema displays. WARNING! 1) If the Motorized Auxiliary Lens
Mount (MALM) is present, ensure to move the MALM to the OUT position before performing
any lens calibrate or reset functions on the Motorized Primary Lens Mount to prevent
collision between the projection lens and the MALM. 2) Hazardous moving parts. Keep
fingers and other body parts away. NOTES: 1) Projector must be fully assembled and powered up in its
final location. 2) Keep clear of rotating parts. Remotely operated motors may start to spin without warning. 3)
Avoid long hair, jewelry, and loose clothing exposure to the knobs during manual adjustment. 4) In case of
emergency, unplug the line cord to immediately halt movement of the lens mount.
A.2.1 Adjust Offset
Project an image with the primary lens only. Always adjust offset before boresight. NOTICE: Ensure the
correct lens is selected in the Advanced Setup: Lens Adjust window before calibration to ensure you will
remain within the applicable boundary of the installed lens.
1. From the Advanced Setup window, select Lens Setup.
2. In the Lens Setup window, ensure
over-write the pre-defined settings for this channel. To change the ILS settings and NOT over-write the
pre-defined settings, clear the Enable Automatic ILS check box. When Enable Automatic ILS is not
selected, changing the channel does not change the position of the ILS. In this case, all adjustments will be
lost when the Enable Automatic ILS check box is selected again.
3. From the Advanced Setup window, select ILS File Setup.
4. Using the framing test pattern, adjust the Offset by clicking the
Adjust window (Figure A-2) as necessary to display a proper image on the screen. NOTES: 1) You can
also hold the buttons down for continuous movement. 2) For best optical performance, make sure to
minimize keystone error by using offset more than aiming to center the image in off axis installations. 3)
Avoid extreme tilts or offsets. Corner vignettes on a white test pattern indicates extreme offset that should
be avoided using mechanical alignment.
