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
level of 100, 50 and 10 W/m
2
are given in the table below.
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. See the installation manual for how to manage
blind sectors.
