WARNING
Radio Frequency Radation 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 and 10 W/m 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 adminis-
tration may require halt of transmission within a certain sector of antenna revolution. This is pos-
sible—Ask your FURUNO representative or dealer to provide this feature.
