Important safety instructions
Your projector has been designed and tested, and meets the latest safety standards for
information technology equipment. However, in order to ensure the safe use of the product, it is
essential to follow the instructions mentioned in the manual and marked on the product.
Please read the manual before using the projector and keep it for future reference.
Please do not look at the projection lens during use, as strong light beam may hurt your eyes.
In some countries/regions, the power supply voltage is unstable. The projector can operate
normally within the voltage range of 100 to 240 (volt) of the AC power supply, but in the areas
that the voltage fluctuation exceeds 10 and the power supply voltage may fluctuate or be cut
off, it is recommended that you connect the projector through a power stabilizer, a surge
protector or an uninterruptible power supply (UPS).
When the projector is working, do not use any object to block the projection lens, otherwise the
object will be heated and deformed, or even fired.
Please do not place the projector on an unstable shelf or a table, otherwise the projector may
fall and maybe seriously damaged.
Do not disassemble the projector before the power to the projector is not cut off. Dangerous
high voltage components are arranged in the projector. Electric shock and death may occur in
case of contact with human body. Therefore, you can open or remove the cover of the projector
in any case. Only qualified professional maintenance personnel can maintain the projector.
Please do not place liquid near or on the projector. If liquid splashes into the projector, the
projector may not work properly. If the projector is wet, the power cord of the projector shall be
unplugged, and then you shall call the authorization service center of the projector for the
maintenance of the projector.

I. Introduction
The projector series of the product is characterized of high brightness and high-definition
resolution, and widely applied to digital high-definition cinemas, large exhibition halls, private
cinemas, large-screen splicing, etc. It is also suitable for digital advertisement display, large-scale
stadium display, city image and project construction. Bright and clear images can be displayed
through the projector by virtue of high brightness output while clear and sharp images are played on
personal computers, cameras and blue-ray players from different signal sources, so that users can
enjoy the visual shocks. Not only that, the projector is conveniently and flexibly applied to large
screen splicing demonstration and used to display more applications of pictures through full control
of PC.

Infrared (IR) remote control sensors are located at front/right/rear sides of the projector. When the
remote controller is held, it is necessary to maintain an orthogonal angle between the remote
controller and the infrared remote-control sensor within 30 degrees, so that the projector can work
normally. The distance between the remote controller and the sensor must not exceed 8m (about 26
feet). Obstacles which will block the infrared beam shall not be located between the remote
controller and the infrared sensor on the projector.
- Replace the battery of the remote controller
8
Open the battery cover as follows: Turn over the remote controller with the back facing up,
press and hold the handle on the battery cover with your fingers, and push the battery cover
according to the direction indicated by the arrow in figure. Open the battery cover.
Take out the existing battery (if necessary), and then put in two AAA batteries according to the
battery polarity indicated on the battery compartment. Align (+) to the positive pole and align (-
) to the negative pole.
Reinstall the battery cover on the battery compartment and push it back to its original position.
Stop pushing the battery cover after hearing a click.
Avoid overheating and overwetting
If the battery is not placed correctly, the remote controller or the battery may be
damaged.
The used batteries shall be treated according to the battery manufacturer's instructions.
Do not throw the battery into the fire, which may cause explosion hazard.
If the battery is dead or you will not use the remote controller for a long time, please take

II. Installation of Projector
9
You can choose the installation location according to your room layout or personal preference.
Factors to be considered include: the size and location of the screen, the location of an appropriate
power socket, and the location of the projector and other equipment as well as the distance between
them.
1. Placement Method
According to the design, there are four locations where the projector can be placed:
Front Desktop
When projection is carried out on the position, the projector
shall be located on the table at front of the screen. This is
the most common way to place projectors, which is fast to
install and easy to move.
Front Ceiling
When projection is carried out on the position, the projector
is hung upside down on the ceiling at front of the screen.
You can purchase a kit for suspension installation of the
projector on ceiling from the dealer, and then install the
projector on the ceiling. After the projector is started, the
mode of Front Ceiling can be set in Basic Setting Menu >
Projector Position Menu.
Rear Desktop
When projection is carried out on the position, the projector
shall be located on the table behind the screen. Please pay
attention that a dedicated rear projection screen shall be
prepared for this installation location. After the projector is
started, the mode of Rear Desktop can be set in Basic
Setting Menu > Projector Position Menu.
