Moving the projector
When moving the projector, take care of the lens and retract the adjustable foot to prevent damage to the
lens and cabinet.
Installing the projector properly
• Please set the projector on nearly-level.
• Be sure to install the projector properly. Improper installation may reduce the laser diode lifetime and
even cause a re hazard.
Adjusting the projector position
When you select a position for the projector, consider the size and shape of your screen, the location of
your power outlets, and the distance between the projector and the rest of your equipment.
Follow these general guidelines:
• Position the projector on a at surface at a right angle to the screen. The projector (with the standard
lens) must be at least 4.7 feet (1.2 m) from the projection screen.
• Position the projector to the desired distance from the screen. The distance from the lens of the
projector to the screen, the zoom setting, and the video format determine the size of the projected
image.
• For the xed short lens, the image exits at a default angle. However, the lens shift feature makes the
image offset variable.
• 360 degrees free orientation operation.
• When installing multiple projectors, keep at least 1m space between the adjacent projectors.
• For ceiling mount installations, make sure to leave 15 mm (0.6”) between the ceiling mount and the
• We are not responsible for the hurt and damage caused by ceiling bracket that purchased from
unauthorized dealer even in warranty period.
• Remove the ceiling bracket immediately while not use.
• While installing, torque screwdriver is suggested, don’t use electric or impact-type screwdriver.
• Please read the manual of bracket for details.
• The bracket is subject to change without notice.

Remote Control Operating Range
The remote control uses infrared transmission to control the projector. It is not necessary to point the
remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or the
rear of the projector, the remote will function well within a radius of about 10 meters (32.8 feet) and 30
degrees above or below the projector level. If the projector does not respond to the remote control, move
a little closer.
Projector and Remote Control Buttons
The projector can be operated using the remote control or the buttons on the rear of the projector. All
operations can be carried out with the remote control; however, the buttons on the projector are limited in
use.
Remote Control Code
The 100 different remote control codes (Remote ID, Code 00 - Code 99) are assigned to this projector.
Switching the remote control codes prevents interference from other remote controls when several
projectors or video equipment next to each other are being operated at the same time. Change the remote
ID on both projector and remote control.
To change the remote ID for the Remote Control:
Press and hold the [Remote ID] button for more than 3 seconds, and the LED indicator (above the [Off]
button of the remote control unit) starts blinking slowly.
Then, input the number between 00-99 by pressing the [0]~[9] buttons to switch the remote ID within 10
seconds.
