MARINE RADAR MODEL 851 MARK-2 C 9-52, Ashihara-cho, Nishinomiya, Japan Telephone: 0798-65-2111 Telefax: 0798-65-4200 Your Local Agent/Dealer All rights reserved. PUB. No. OME-34900 MODEL 851 MARK-2 (TENI) FIRST EDITION: JUNE 2000 Printed in Japan i Do not open the equipment. Hazardous voltage which can cause electrical shock, burn or serious injury exists inside the equipment. 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 ELECTRICAL SHOCK HAZARD Stay away from transmitting antenna. The radar antenna emits mi- crowave radiation which can be harmful to the human body, particularly the eyes. Never look directly into the antenna radiator from a distance of less than 1 m when the radar is in operation. Turn off the radar power switch before servicing the antenna unit. Post a warn- ing sign near the switch indicating it should not be turned on while the antenna unit is being serviced. Prevent the potential risk of someone begin struck by the rotating antenna and expo- sure to RF radiation hazard. WARNING 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 equipment is emitting smoke or fire. Fire or equipment damage can result if a different cable is used. Keep heater away from equipment. Heat can alter equipment shape and melt the power cord, which can cause fire or electrical shock. CAUTION Use the proper fuse. Use of a wrong fuse can result in fire or permanent equipment damage. A warning label is attatched to the display unit. Do not remove the label. If the label is missing or damaged, contact a FURUNO agent or dealer. SAFETY INSTRUCTIONS WARNING To avoid electrical shock, do not remove cover. No user-serviceable parts inside.
