Important Safety Instructions
The projector should use AC power. Make sure that the main voltage and capacitance match the rated
power of the projector. If the installation environment cannot meet the AC power requirements, please
contact the electrician.
The installation can only be carried out by qualified technical personnel in accordance with local electrical
codes and regulations.
This device uses a three-terminal power cable that includes a single-phase line that protects the ground
wire (PE). If the installation environment cannot meet the AC power requirements, please contact the
electrician. Do not ignore the role of grounding.
Turn off the power to the projector and unplug the power cord to cut off all power connections from the
projector.
If you need to extend the cable, use a power cable with the current rated value not lower than that of the
projector. If the rated value of the power cable is lower than the current value of the projector, it may cause
overheating.
Do not disassemble the projector. When it needs to be maintained or repaired, hand it over to a trained
and authorized service person.
Do not spill any liquid on the projector.
To better protect the product during thunderstorms or when it is not used for a long period of time, unplug
the power plug from the wall socket. This can prevent lightning or power line surges from causing damage
to the projector.
