1. If the image suffers from slight keystone effect, it can be corrected with electronic cropping.
2. If the keystone effect is severe, unevenly adjust the feet to compensate for projector tilt.
Christie recommends using the lens offset to align the center of the image to the center of the
screen before correcting the keystone effect.
3. If one side of the image is longer than another, adjust the tilt and level of the projector.

Warning! If not avoided, the following could result in death or serious injury.
•
This procedure must be performed by Christie qualified technicians.
Caution! If not avoided, the following could result in minor or moderate injury.
•
Do not look directly into the lens when the light source is on. The extremely high brightness can
cause permanent eye damage.
When performing boresight adjustments, the goal is to balance the tilt of the lens mount to
compensate for screen-to-projector tilt but also to precisely maintain the original factory settings of
the lens mount axial position.
1. Loosen the lock screws highlighted in the image below.
2. Extend the lens focus completely.
