Installation and Setup
Precautions for Installation
Place the projector in a horizontal position.
The tilt angle of the projector should not exceed 15 degrees, nor should the projector be
installed in any way other than the desktop and ceiling mount, otherwise lamp life could
decrease dramatically, and may lead to other unpredictable damages.

• Ensure that the intake vents do not recycle hot air from the exhaust vent.
• When operating the projector in an enclosed space, ensure that the surrounding air
temperature within the enclosure does not exceed operation temperature while the
projector is running, and the air intake and exhaust vents are unobstructed.
• All added enclosures should pass a certied thermal evaluation to ensure that the
projector does not recycle exhaust air, as this may cause the device to shutdown even
if the enclosure temperature is with the acceptable operation temperature range.
Caution:
Ceiling installation must be done by a qualied professional. Contact your dealer for more information. It is
not recommended you install the projector by yourself.

Caution for Ceiling Mounting Installation
When installing the projector other than desktop front or rear installation, please read
below notice carefully. mounting installation.
For ceiling mounting installation, please use UL Listed ceiling mounts and M4 screws,
maximum depth of screw: 12 mm, the distance from wall to projector must be kept 30cm at
least for proper ventilation.

Projector Installation
The high quality display effect can be guaranteed only when the projector is correctly
installed. Generally, the light source facing the screen should be reduced or eliminated as
much as possible. The contrast of the image will be obviously reduced if the light directly
shines on the screen, such as the beam from windows or the searchlight cast on the
image. The image may become faded and not bright. The available installation options as
below.
Desktop Front
Install the projector on the table and project
the image forward.

Upward or Downward Installation
The projector can be installed in addition to the desktop and installed in the ceiling, but
also can be mounted up or down for upward or downward projection. When the projector is
projected upward or downward, please set Projection Mode (SETUP->Projection Mode) to
Upward Front or Downward Front. Refer to the following illustration to set Projection Mode.
Please note that lamp life may be reduced, contact your local dealer for more
information

order to maintain proper operating temperature of the projector.
• Incorrect Projection Mode setting may affect hot air exhausting from the projector the heat, high temperature
may cause the projector goes into system protection, component damage or lamp damage.
• Brightness decay of upward or downward installation is faster than desktop or ceiling installation. Refer to
laboratory test results, Lamp life may be reduced to 50-75% of the life which the projector is installed by
Desktop or Ceiling installation. Recommend to regularly check the lamps and the brightness of projected
image, please consult your local dealer before the projector is installed upward or downward.

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 control will function well
within a radius of about 10 meters (32 feet) and 15 degrees above or below the projector
level. If the projector does not respond to the remote control, move a little closer.

Important:
• Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency fluorescent
lights can disrupt remote control operation.
• Be sure nothing obstructs the path between the remote control and the projector.
• Do not expose the remote control to high temperature or humidity; otherwise, the remote control will not
work functionally.
