Mounting; Basic Optical Alignment - Christie Mirage M Series Setup Manual

2.1.1 Mounting

There are several methods for mounting the projector. In typical front and rear screen installations the projector
can be mounted to a secure and level surface, such as a table or cart. Carts are useful when the projector has to
be moved often. Lock the wheels on a cart, when it is in position, to prevent accidental movement during a
presentation.
Ceiling Mount
The projector can be inverted and suspended from the ceiling using a specially designed ceiling mount fixture
118-100108-XX. This mounting is recommended for those that want the projector out of plain view or have
limited amount of space for the projector. For more information, contact your dealer.

2.1.2 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 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.
4. If necessary, center the image on the screen: If the projector is mounted off center to the screen axis,
then offset the lens as much as required. Aim the projector over slightly towards the center of the screen,
but use caution when doing so, as too much tilt will cause excessive keystone distortion. Lens offset will
not.
5. Re-check side-to-side leveling: With the framing pattern on screen, double-check projector leveling so
the top edge of the image is parallel to the top edge of the screen.
6. Throw Distance: Ensure the projector is positioned in the throw distance range for the particular lens.
