The projector must be installed by qualified technicians in order to ensure proper operation and reduce the risk
of bodily injury.
In addition, the ceiling must be strong enough to support the projector and the installation must be in accordance
with any local building codes. Please consult your dealer for more information.

General

• Single-chip DLP projector with high resolution and high brightness
Realized to project the image in the resolution 1920 × 1200 pixels (WUXGA), the aspect ratio in 16:10, and the
brightness in 8000 lumens.
Light source · Brightness
• A long-life laser diode is equipped in the light module
The product can be operated at low cost because the laser light source can be used for a long time without requir-
ing replacement or maintenance.
• Brightness can be adjusted within a wide range
Unlike with ordinary light sources, the brightness can be adjusted from 20 to 100% in 1% increments.
• [CONSTANT BRIGHTNESS] mode
Brightness normally decreases with use, but by selecting [CONSTANT BRIGHTNESS] mode, sensors inside the
projector detect and automatically adjust the output, thereby maintaining constant brightness throughout the life
of the light module.
However, if brightness output is set at the maximum, brightness will decrease with use.

Installation

• Wide range of optional lenses selectable according to the place of installation
This projector supports 8 types of optional lenses, providing a selection of lenses adapted to a variety of places
of installation and projection methods.
In addition, the lenses can be mounted and removed in one touch.
Note that no lens is mounted upon shipment from the factory. Please purchase optional lenses separately.
• This projector can be installed any angle within vertical and horizontal 360° range, however, life of optical
parts will be shorten in the following installation state:
• When the projector is installed on which lens faces downward.
• When the intake vent on the projector side faces downward in the portrait installation. (See page 154)
• Double stackable for high light output projection
By stacking 2 projectors, increased brightness on a large screen is possible.
• Power lens control for quick and easy adjustment
By using buttons on the projector or the remote control, zoom, focus, and position (lens shift) can be adjusted.
. The remote control can be used wirelessly.
