2.3.3 Adjusting Projector Height/Tilt

Adjusting Height
You can modify the height of the projector to remedy a slightly uneven mounting surface by adjusting the four
feet threaded into the bottom chassis. Turn each foot clock-wise or counter-clockwise until the projector is
level on all sides. Refer to
Tilting the Projector
In the landscape orientation, the projector can be rotated to any angle (roll/pitch) and tilted to any vertical angle
(i.e., you can tilt the face of the projector up or down as much as desired for your installation). For maximum
lamp life, side-to-side tilt must not exceed 15 degrees. Tilt angles including portrait mode are allowed as
shown in Figure

2.3.4 Basic Optical Alignment

Only perform image alignment on-ce the projector is fully assembled and powered up in its final location.
Basic image alignment ensures the image reflected from the DMDs is parallel to 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 ensure the projector is properly positioned
relative to the screen.
Basic Optical Alignment Procedure
1. Display a test pattern: Appropriate for analyzing image focus and geometry, such as the "framing" test
pattern showing the cross-hair centered across the image. Press the T
the built-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.
