SAFETY INSTRUCTIONS
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
level of 100, 50 and 10 W/m
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.
