SAFETY INSTRUCTIONS
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 W/m 2 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, it may
be necessary to prevent transmission in that area to protect passengers and crew from
microwave radiation. This can be done with Sector Blank in the System menu.
