Section 2: Installation and Setup

2.2.4 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 104-
100001-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.
WARNING
Special Mounting
The projector can also be rotated (front-to-back) up to 360 degrees and fixed in a rotated position without
affecting performance. However, the side-to-side tilt limit of the projector must not exceed +/-15 degrees, to
ensure optimal performance of the projector.

2.2.5 Adjusting Projector Height/Tilt

Adjusting Height
You can modify the height of the projector to remedy a slightly uneven mounting surface by adjusting the two
feet threaded into the bottom chassis. Turn each foot clock-wise or counter-clockwise until the projector is
level on all sides.
Adjusting Tilt
1. Before adjusting tilt, ensure the projector is centered.
screen tilt, or measure this incline with a protractor at the screen.
2. Then tilt the projector to closely match the screen tilt angle by extending or retracting the adjustable feet on
the projector.
NOTE: 1) 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. Select 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.

2.2.6 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.

the installation instructions and safety guidelines provided in the kit.
