Product Overview
The projector consists of the DLP projector controller, Lamp controller,
Power supply system, And the system cooling controller.
The DLP controller captures the digital PC date and video date And converts them into the
DMD display device.
The lamp controller controls the lamp’s power and synchronizes its frequency whit color
display sequence.
Power supply unit controls the AC line power factor and converts primary voltage to
secondary low voltage for digital board.
The system cooling controller drives the airflow to cool the lamp’s heat and electrical
component’s heat.

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.
