WARNING
Radio Frequency Radiation Hazard
The radar antenna emits electromagnetic radio frequency (RF) energy which can be
harmful, particularly to your eyes. Never look directly into the antenna aperture from a
close distance while the radar is in operation or expose yourself to the transmitting
antenna at a close distance.
Distances at which RF radiation levels of 100, 50 and 10 W/m are given in the table
below.
Note: If the antenna unit is installed at a close distance in front of the wheel house,
your administration may require halt of transmission within a certain sector of antenna
revolution. This is possible. Ask your FURUNO representative or dealer to provide
this feature.
