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 trans-
mitting antenna at a close distance.
Distances at which RF radiation levels of
100 and 10 W/m
2
exist 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.
