3. Physical installationProjector centering1. If the projector is standalone in front of the port window, center the projector with the theatre screen (see ref A image 3-2).2. If a film projector is already present (projector will be off-center), try to optimize aim (see ref B image 3-2).Note: Unlike film projectors, it is best to keep the projector lens surface as parallel to the screen as possible, even if it issignificantly above the screen center.The off-center position slightly increase side keystone, but will minimize horizontal lens offset required.SCREEN CENTER SCREEN CENTEROFF-CENTERA BImage 3-2Projector centering3. Proceed to leveling the projector by adjusting the feet of the projector as follows:- Loosen the nuts (A), using a wrench of 17 mm, on the threaded rod.- Adjust the height of the 3 legs (B) to level the projector, using a 14 mm wrench.- Secure the leg height by tightening the nuts (A).Note: There must be at least 5 cm between the bottom side of the projector and the pedestal.BAImage 3-3Projector leveling4. Later, when the projector is up-and-running, adjust precise image geometry and placement.Projector tiltingIn an ideal installation, the DP2K C-series projector lens surface is centered with and parallel to the screen. This orientation helpsto ensure optimized lens performances with minimal offset. If this position is not possible (such as when the projector is significantlyhigher than the center of the screen), it is better to rely on offset rather than extra tilt.1. Before adjusting tilt, make sure the projector is as well-centered with the theatre screen as possible for your installation area.2. Check with theatre personnel for the degree of screen tilt, or measure this incline with a protractor at the screen.3. Tilt the projector to closely match this screen tilt angle as follows:14 R5905050 DP2K C-SERIES 10/07/2012
