Only qualified personnel should work inside the equipment. Turn off the radar power switch before servicing the antenna unit. Post a warning sign near the switch indi- cating that it should not be turned on while the antenna unit is being serviced. Prevent the potential risk of being struck by the rotating antenna and exposure to RF radiation hazard. 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. WARNING Use the proper fuse. Use of a wrong fuse can damage the equipment and void the warranty. Keep heater away from equipment. Heat can alter equipment shape and melt the power cord, which can cause fire or electrical shock. NOTICE 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. WARNING To avoid electrical shock, do not remove cover. No user-serviceable parts inside.

NOTICE Observe the following compass safe distances to prevent interference to a magnetic compass: Standard Steering compass compass TBA TBA Antenna unit TBA TBA Display unit Do not open the equipment unless totally familiar with electrical circuits and service manual. 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. WARNING 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 antenna mast. Be sure that the power supply is compatible with the voltage rating of the equipment. Connection of an incorrect power supply can cause fire or damage the equipment. Use only the specified power cable. Fire or equipment damage can result if a different cable is used.

i SAFETY INSTRUCTIONS WARNING Do not disassemble or modify the equipment. Fire, electrical shock or serious injury can result. Immediately turn off the power at the switchboard if the equipment is emitting smoke or fire. Continued use of the equipment can cause fire or electrical shock. Contact a FURUNO agent for service. Keep heater away from equipment. A heater can melt the equipment's power cord, which can cause fire or electrical shock. Use the proper fuse. Fuse rating is shown on the equipment. Use of a wrong fuse can result in damage to the equipment. ELECTRICAL SHOCK HAZARD Do not open the equipment. Only qualified personnel should work inside the equipment. CAUTION A warning label is attached to the equip- ment. 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. Name: Warning Label (1) Type: 86-003-1011-0 Code No.: 100-236-230 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/m 2 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. MODEL Distance to 100 W/m 2 point Distance to 10 W/m 2 point 1722 Nil Worst case 0.50 m 1732 1742 1762 0.20 m Nil Worst case 0.50 m Nil Worst case 1.00 m Worst case 3.00 m No one navigation device should ever be solely replied upon for the navigation of a vessel. Always confirm position against all available aids to navigation, for safety of vessel and crew. CAUTION 1752 0.15 m Worst case 2.00 m
