WARNING
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 halt transmission within a certain sector of antenna
revolution. This can be done from the SCANNER menu.
