Safety Instructions, Radio Frequency Radiation Hazard

SAFETY INSTRUCTIONS

WARNING

		Do not open the equipment
		unless totally familiar with
		electrical circuits and
		service manual.
	ELECTRICAL	Only qualified personnel
	ELECTRICAL	should work inside the
	SHOCK	should work inside the
	HAZARD	equipment.

		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 mast.

Construct a suitable service platform from which to install the antenna unit.

Serious injury or death can result if some- one falls from the radar mast.

Turn off the power at the mains switch- board before beginning the installation.

Fire, electrical shock or serious injury can result if the power is left on or is applied while the equipment is being installed.

CAUTION

Ground the equipment to prevent electrical shock and mutual interference.

Observe the following compass safe distances to prevent deviation of a magnetic compass.

WARNING

Radio Frequency

Radiation Hazard

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 trans- mitting antenna at a close distance.

Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below.

Note: 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. This is possible - Ask your FURUNO representative or dealer to provide this feature.
