Adjust Tilt And Level The Projector - Christie CP 2210 User Manual

2. Position the projector at an appropriate throw distance (projector-to-screen distance) and vertical position.
Ideally, center the projector with the theatre screen. If competing for space with an already present film
projector, aim the projector slightly off-center, as shown in Figure 2-1. This will slightly increase side
keystoning, but will minimize the horizontal lens offset required. NOTE: Unlike film projectors, it is best
to keep the projector lens surface as parallel to the screen as possible, even if significantly above the
screen center. When a particularly short throw distance combines with a very wide screen, you may have to
forfeit some aim and stay more parallel to the screen. In such cases, some lens offset can reduce the
keystone distortion.
3. Once you have completed the remaining installation steps and the projector is up-and-running, adjust
precise image geometry and placement, as described in
2.4

Adjust Tilt and Level the Projector

NOTICE: The front-to-back tilt of the projector must not exceed 15°. This limit ensures safe lamp operation
and proper position of the liquid cooling reservoir in the projector.
For an ideal installation, the CP2210 lens surface should be centered and
parallel to the theatre screen. This orientation helps to ensure optimized lens
performance with minimal offset. Choose a sturdy mounting surface that
allows for this. If this position is not possible (such as when the projector is
significantly higher than the center of the screen), it is better to rely on
offset rather than extra tilt. Check with theatre personnel for the degree of
screen tilt or measure this incline with a protractor at the screen. Tilt the
projector to match the screen tilt angle by extending or retracting the 4
adjustable projector feet. For best optical performance, avoid tilting the
projector excessively. Use vertical offset of the lens instead.
To adjust the height or level of the projector, extend or retract the adjustable
feet located on the bottom of the projector by rotating them. Once the
required adjustment is made, tighten the lock nut (Figure 2-2).
