SAFETY INSTRUCTIONS Read these safety instructions before you operate the equipment. WARNING Indicates a condition that can cause death or serious injury if not avoided. CAUTION Indicates a condition that can cause minor or moderate injury if not avoided. Warning, Caution Prohibitive Action Mandatory Action WARNING Radio Frequency Radiation Hazard The radar antenna sends the electromagnetic radio frequency (RF) energy. This energy can be dangerous to you, especially your eyes.
SAFETY INSTRUCTIONS WARNING ELECTRICAL SHOCK HAZARD WARNING Use the correct fuse. Do not open the equipment. Only qualified persons can work inside the equipment. Turn off the power before you service the antenna unit. Post a warning sign near the power switch not to turn on the power while you service the antenna unit. Prevent the potential risk of being struck by the rotating antenna and exposure to RF radiation hazard. When you work on the antenna unit, wear a safety belt and hard hat.
SAFETY INSTRUCTIONS WARNING Do not depend on one navigation device for the navigation of the ship. The navigator must check all aids available to confirm position. Electronic aids are not a replacement for basic navigation principles and common sense. · The ARPA automatically tracks an automatically or manually acquired radar target and calculates its course and speed, indicating them by a vector.
