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. It is recommended that the radiant section be installed at a high
place such as on the roof of the wheelhouse, on the flying bride, 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 center 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.
When conducting maintenance work, make sure to turn off the power so that
the power supply to the equipment is completely cut off.
Some equipment components can carry electrical current even after the
power switch is turned off, and conducting maintenance work may result in
electric shock, equipment failure, or accidents.
