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.
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 and 10 W/m
2
exist
are given in the table below.
