Projector Installation Notice
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.
Allow at least 50 cm clearance around the exhaust vent.
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 5 - 35°C while the projector is running, and the air intake and
exhaust vents are unobstructed.
All enclosures should pass a certified 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 5 - 35°C range.
Power Safety
Only use the supplied power cord.
Do not place anything on the power cord. Place the power cord where it will not be in the way of
foot traffic.
Remove the batteries from the remote control when storing or not in use for a prolonged period.

depth of 6 mm (0.23 inch).
The construction of the ceiling mount must be of a suitable shape and strength. The ceiling mount

Remote Control Parts
Important:
1. Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency
fluorescent lights can disrupt remote control operation.
2. Be sure nothing obstructs the path between the remote control and the projector. If the path
between the remote control and the projector is obstructed, you can bounce the signal off certain
reflective surfaces such as projector screens.
3. The buttons and keys on the projector have the same functions as the corresponding buttons on the
remote control. This user’s manual describes the functions based on the remote control.

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 7 meters (23 feet) and
15 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 top of the projector. All
operations can be carried out with the remote control; however, the buttons on the projector are lim-
ited in use.
