Adjust Tilt and Level the cinema projector

WARNING
the cinema projector's feet.
WARNING
the cinema projector's baseplate.
The lens should be centered and parallel with the screen to ensure optimum lens performance with minimal
offset. If this position is not possible, it is better to rely on offset rather than extra tilt.
Use a protractor to measure the degree of screen tilt and then extend or retract the cinema projector feet to
match this angle.
NOTES: The front-to-back tilt of the cinema projector must not exceed 15°. This limit ensures safe lamp
operation and the proper positioning of the liquid cooling reservoir.
To adjust the vertical or horizontal position of the cinema projector,
extend or retract the adjustable feet on the bottom of the cinema
projector by rotating them. Once the required adjustment is made,
tighten the lock nut.
If you need to adjust the vertical or horizontal position of the cinema
projector beyond what the standard feet allow, you can install two 6
inch extension rods to increase the amount of adjustment. To install the
extension rods safely:
1. Prop the rear of the cinema projector up to access and remove the
two rear feet. This can be done by one person holding the back end
of the cinema projector up slightly so another person can unthread
the feet OR by propping up the back of the cinema projector with a
sturdy object.
