Only qualified personnel should work inside the 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 antenna mast. Do not disassemble or modify the equipment. Fire, electrical shock or serious injury can result. Turn off the power immediately if water leaks into the equipment or the equip- ment is emitting smoke or fire. Continued use of the equipment can cause fire or electrical shock. Use the proper fuse. Use of a wrong fuse can damage the equipment and void the warranty. WARNING LABEL A warning label is attached to the equipment. Do not remove the label. If the label is missing or damaged, contact a FURUNO agent or dealer about replacement. WARNING To avoid electrical shock, do not remove cover. No user-serviceable parts inside.

CAUTION 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 and 10 W/m 2 exist are given in the table below. 100 W/m 2 10 W/m 2 0.1 m1.8 m

The instrument so called Radiation Hazard Meter is used. The meter indicates the radiation power density in the readout of xx mW / square cm. We convert the readout into xx W / square m, and measure the distance to get the readout of 100 W/square m and 10 W/square m. Best regards, K.
