General Safety Information
Do not open the unit case. Aside from the projection lamp, there are no user-serviceable parts in
the unit. For servicing, contact qualified service personnel.
Follow all warnings and cautions in this manual and on the unit case.
The projection lamp is extremely bright by design. To avoid damage to eyes, do not look into the
lens when the lamp is on.
Do not place the unit on an unstable surface, cart, or stand.
Avoid using the system near water, in direct sunlight, or near a heating device.
Do not place heavy objects such as books or bags on the unit.

–iii –
Projector Installation Notice
Do not tilt the projector to the left or right, otherwise lamp life could decrease dramatically, and
may lead to other unpredictable damages.
There is no limit on the tilt angle upward or downward.
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 operation temperature 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 operation temperature range.

Verify Installation Location
To supply power, the 3-blade (with earthing lead) socket should be used to ensure proper
grounding and equalized ground potential for all of the equipment in the Projector System.
The power code provided with the Projector should be used. In case of any missing item, other
qualified 3-blade (with earthing lead) power cord can be used as substitution; however, do not use
2-blade power cord.
Verify if the voltage is stable, grounded properly and there is no electricity leakage.
Measure total power consumption which should not higher the safety capacity and avoid safety
issue and short circuit.
Turn on Altitude Mode when located in high altitude areas
The projector can only be installed upright or inverted.
When installation the bracket, make sure the weight limit is not exceed and firmly secured.
Avoid installing near air conditioner duct or subwoofer.
Avoid installing at high temperature, insufficient cooling and heavy dust locations.
Keep your product away from fluorescent lamps (>1 Meter) to avoid malfunction
caused by IR interference
The VGA IN connector should be connected to the VGA IN port. Note that it should be inserted
tightly, with the screws on both sides securely fastened to ensure proper connection of the signal
wire for achieving optimal display effect.
The AUDIO IN connector should be connected to the AUDIO IN port and CANNOT be connected
to AUDIO OUT or other ports like BNC, RCA; otherwise, it will lead to mute output and even
DAMAGE the port.
Install the projector above 200cm to avoid damage.
The power cord and signal cable should be connected before power on the projector. During the
projector starting and operating process, DO NOT insert or remove the signal cable or the power
cord to avoid damaging the projector.
Cooling notes
Air outlet
Make sure the air outlet is 50cm clear of any obstruction to ensure proper cooling.
Air outlet location should not be in front of the lens of other projector to avoid causing illusions.
Keep the outlet at least 100cm away from the inlets of other projectors
The projector generates a massive amount of heat during use. The internal fan dissipates the heat
of the projector when shutting down, and such process may continue for a certain period. After the
project enters STANDBY MODE status, press the AC power button to turn off the projector and
remove the power cord. DO NOT remove the power cord during the shutdown process, as it may
cause damage to the projector. In the meantime, the delayed heat radiating will also affect the
service life of the projector. The shutdown process may vary depending on the model used.
Whatever the case may be, be sure to disconnect the power cord till after the projector enters the
STANDBY status.
Air inlet
Make sure there is no object blocking air input within 30 cm.
Keep the inlet away from other heat sources
Avoided heavy dust area

–v –
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.
Replacing the Lamp
Replacing the lamp can be hazardous if done incorrectly. See Replacing the Projection Lamp on page 55
for clear and safe instructions for this procedure. Before replacing the lamp:
Unplug the power cord.
Allow the lamp to cool for about one hour.
Cleaning the Projector
Unplug the power cord before cleaning. See Cleaning the Projector page 59.
Allow the lamp to cool for about one hour.
Regulatory Warnings
Before installing and using the projector, read the regulatory notices in the Regulatory Compliance on
page 78.

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.
Note:
Complies with FDA performance standards for laser products except for deviations pursuant to
Laser Notice No. 50, dated June 24, 2007
Caution:
Use of controls, adjustments or performance of procedures other than those specified herein
may result in hazardous laser light exposure.

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 limited in
use.
