Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
can result in minor or moderate injury.

Radio Frequency Radiation Hazard
The radar antenna emits the electromagnetic radio frequency (RF) energy which can be harmful,
particularly to your eyes. Do not look at the Antenna Unit from a close distance while the radar is in
operation, or expose yourself to the transmitting antenna at a close distance.
The distances at which RF radiation levels of 10 W/m
2
exist are shown in the table below.
DO NOT approach closer than 9.1m (Safety standard is 10 W/m
2
) when radar is transmitting.
NOTE: This value is applied when radar is installed in a public space. Value is defined as on
human body surface over a 6-minute period with the flux density averaged from the measurement.
Moreover, this measured value is measured by pointing the center of the antenna towards a
human. However this is the worst value, definition required by actual regulation is written here as
on safe side.
Do not open the radome.
Electrical shock can occur. Only qualified personnel should work inside the equipment.
Turn off the circuit breaker in the JCU if opening the radome is required.
Wear a hard hat and safety belt when mounting the Antenna Unit.
Serious injury or death can result from falls or dropped items while installing or servicing the
radar components.
Do not use any other power except 100 to 240 VAC.
Connection of an incorrect power supply can cause fire or damage the equipment.
Turn off the power immediately if water leaks into the
equipment or smoke or fire is coming from the equipment.
Failure to turn off the equipment can cause fire or electrical shock.
Do not operate the equipment with wet hands.
Electrical shock can occur.
