Mounting the D-73d
There are several methods for mounting the projector. Depending on your chosen
installation, one method may be more suitable than another.
Floor Mounting (Upright) 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 moving a projector during a
presentation or from site to site. If possible, lock the wheels when it’s in position to prevent
it from being moved during a presentation.
Ceiling Mounting
(Inverted)
For fixed installations, and for those that want the projector out of sight or have a limited
space for projector and audience, you can invert the D-73d and suspend it from the
ceiling using a specially-designed ceiling mount fixture.
Install the ceiling mount kit according to the instructions provided with the kit.
Installing the Projector in
an Enclosure
The projector can also be inverted and placed in an enclosure above and behind the
viewing area. Install four feet on the inside bottom surface of the enclosure on which the
projector can rest. A variety of materials can be used for this purpose (for example, rubber
crutch tips or turntable feet).
Adjusting the Projection
Angle
If the D-73d is ceiling-mounted and the screen is significantly lower than the projector, you
can tilt the projector at a slight angle by adjusting the ceiling mount. If you do this, you may
need to use the mechanical lens shift and/or OSD image alignment controls, to
compensate. For detailed instructions, refer to Power-Up Sequence and Optical
Alignment Procedure on page 51.
The projector can be tilted front-to-back up to 20 degrees and mounted without it
affecting performance. However, to ensure proper operation when displaying 3D content,
avoid mounting the projector at a side-to-side angle; see Figure 3-11.
