Adjust Projector Height and Tilt

2.5.1 Adjust Height

You can modify the height of the projector to remedy a slightly uneven mounting surface by adjusting the three
feet threaded into the bottom chassis. Turn each foot clock-wise or counter-clockwise until the projector is
level on all sides.
The front feet are adjusted by turning the collar and the feet do not rotate when adjusted. The rear foot is
adjusted by turning the entire

2.5.2 Adjust Tilt

1. Before adjusting tilt, ensure the projector is centered.
NOTE: Check with site personnel for the degree of screen tilt, or measure this incline with a protractor at
the screen.
2. Tilt the projector to closely match the screen tilt angle by extending or retracting the 3 adjustable feet.
NOTE: For an ideal installation, the lens surface should be centered and parallel to the 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.

Basic Optical Alignment

Only perform image alignment once the projector is fully assembled and powered up in its final location. Basic
image alignment ensures the image reflected from the DMDs is parallel and well-centered with the lens and
screen. This initial optical alignment is the foundation for optimizing images on the screen and must be
completed before final boresight adjustments. Before beginning, make sure the projector is properly positioned
in relation to the screen.
Basic Optical Alignment Procedure
1. Display a test pattern: Appropriate for analyzing image focus and geometry, such as the Grid test pattern
showing the cross-hair centered across the image. Press the T
in keypad and press the soft key that displays Test on the LCD display.
2. Course focus: Do a quick preliminary focus and (if available) zoom adjustment with the primary lens. Do
not worry about consistency across the image at this point, just center focus. It is good practice to have
zoom adjustment color and focus adjustment color in the center of its range.
3. Center the image in the lens: Holding a piece of paper at the lens surface, adjust offsets as necessary until
the image is centered within the lens perimeter. A full white field works best for this.
