WARNING WARNING
Keep the area around the
antenna free of ropes and other
items that may get tangled.
If the antenna becomes tangled,
damage to the equipment or
injury to personnel may occur.
Radio Frequency Radiation Hazard
The radar antenna emits electromagnetic radio frequency (RF) energy that 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 level of 100,
2
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.
