Operation Requirements
Do not place or install the radar in a place exposed to sunlight or near the heat source.
Keep the radar away from dampness, dust or soot.
Keep the radar installed horizontally on the stable place to prevent it from falling.
Do not drop or splash liquid onto the radar, and make sure there is no object filled with liquid
on the radar to prevent liquid from flowing into the device.
Install the radar in a well-ventilated place, and do not block the ventilation of the device.
Operate the radar within the rated range of power input and output.
Do not disassemble the radar.
Transport, use and store the radar under the allowed humidity and temperature conditions.
Electrical Safety
Use the recommended power cables in your area and conform to the rated power
specification.
Use the power adapter provided with the radar; otherwise, it might result in people injury and
device damage.
The power source shall conform to the requirement of the Safety Extra Low Voltage (SELV)
standard, and supply power with rated voltage which conforms to Limited power Source
requirement according to IEC60950-1. Please note that the power supply requirement is
