Position the Cinema Projector

1. If you are installing the cinema projector in the optional rack stand (P/N 108-282101-02) follow the
instructions provided with the rack stand to install it.
2. Position the cinema projector at an appropriate throw distance (cinema projector-to-screen distance) and
vertical position. Ideally, center the cinema projector with the theatre screen. If space is limited, you can
aim the cinema projector slightly off-center. This increases side keystoning, but reduces the horizontal lens
offset required.
NOTE: Keep the cinema projector lens 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 key-
stone distortion.
3. Attach the supplied safety strap to the back of the cinema projector and fasten it to its mounting surface.
Use of the strap is mandatory to prevent the cinema projector from tipping when a lens or auxiliary lens
mount is installed. NOTE: If you are using the optional rack stand, it is strongly recommended you use the
hold down clamp (116-100101-01) in addition to the rear safety strap to firmly secure the cinema
projector's rear feet.

Adjust Tilt and Level the Cinema Projector

WARNING
cinema projector feet.

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.
NOTE: TThe 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.
