Wear a safety belt and hard hat when working on the antenna unit.
Serious injury or death can result if someone falls from the radar antenna
mast.
DANGER
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 W/m

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.
The installer of the equipment must read these safety instructions before attempting to install the
equipment.
