When turning off the power supply, do not hold down the power button of the
operation unit.
Otherwise, a trouble may occur due to termination failure.
Never directly touch the internal components of the radar antenna or indicator. Direct
contact with these high-voltage components may cause electric shock. For
maintenance, inspection, or adjustment of equipment components, consult with our
branch office, branch shop, sales office, or our distributor in your district.
Do not get close to the radiant section of the radar antenna.
It is a rotating part, and it may cause injuries if it suddenly starts rotating and
consequently hits the body. The radiant section be installed at a high place such as
on the roof of the wheelhouse, on the flying bridge, on the trestle, or on the radar
mast so that no one can get close to it.
Microwave radiation level of the radar antenna
Keep away from the radar antenna during transmission.
Microwaves are generated from the front centre of the radiant section of the radar
antenna at the levels indicated in the table below. Exposure to microwaves at close
range can result in injury (especially damage to eyes).

Make sure to install the radar antenna at a place higher than human height.
Direct exposure to electromagnetic wave at close range will have adverse effects on
the human body.
When it is necessary to get close to the radar antenna for maintenance or inspection
purposes, make sure to turn the power switch of the display unit to "OFF" or "STBY".
Direct exposure to electromagnetic waves at close range will have adverse effects
on the human body.
