Installation
■ Installation methods
There are four ways to install this unit:
on a table in front of the screen.
mounted on the ceiling in front of the screen.
on a table behind a semi translucent screen.
mounted on the ceiling behind a semi translucent screen.
Set the method you use on the 4 section of the MENU described later. (see page 21.)
Place the unit on a standard height table to project and view the image
from in front of the screen. The height from the bottom of the unit to the
center of the lens is 12.4 cm (4”-7/8).
There are two kinds of brackets (low ceiling and high ceiling, sold
separately) available which can be used to mount the unit on the ceiling.
Consult your dealer for details on their use, and have installation done by
either your dealer or a reputable contractor.
The image on the screen is vertically reversed compared to that of a table
mounted installation. In this case, please set the installation type to
FRONT/CEILING in the 4 section of the menu. (see page
21.)
In this case, images are projected onto a semi translucent screen, and the
viewer watches it from the reverse side. The relationship with the screen
and projection distance corresponds to that for front projection. For rear
projection, set the installation type to REAR/CEILING or REAR/TABLE
in the 4 section of the menu. (see page 21.)
