Adjusting The Los Coupling Mirrors - Christie CineLife+ CP4415-RGB Service Manual

Repeat for the vertical lock screw (lock C in the images in step 2).
Continue the gradual tightening of each screw, until all lock screws are tight.
When stabilizing image vibration, lock B may be left locked or unlocked at the discretion of the
installer.
15. If you used the focus knob (F in the images in step 2) to make the adjustments manually, run
an ILS auto calibration.
16. Fine tune the focus on cross-hair patterns I (horizontal) and II (vertical) using the ILS
controls only.
The goal is to obtain good focus at the center and on all sides of the screen, including the
square patterns across the screen.

Adjusting the LOS coupling mirrors

Learn how to adjust the Laser Optical Subsystem (LOS) coupling mirrors.
The LOS coupling mirrors can only be adjusted after replacing an optical module such as the LOS,
integrator, and coupling mirror assembly. The coupling mirror screws are potted in position from
production and not adjustable without replacing the mirror.
1. If the projector is equipped with LiteLOC, disable this feature so the RGB controls can be
accessed.
2. On a tripod in front of the lens, set up an illuminance meter (such as the Konica Minolta T10
Illuminance Meter) positioned in the center of the projection beam sent to the screen.
The illuminance meter must be facing the lens.
3. Navigate to the laser power setting page, and decrease the red laser power to low (30% to
40%).
4. Set the green and blue laser power levels to 0.
5. Turn on the light source.
6. Display a white test pattern on the screen.
7. Wait one minute for the lasers to stabilize.
8. Remove the electronics-side cover (on page 46).
9. Adjust the LOS coupling mirrors independently to maximize the lux reading on the illuminance
meter.
Only small adjustments are necessary. You can use a small 2.5 mm flathead screwdriver bit.
