INTRODUCTION ■■PRECAUTIONS DDFor Display unit: RRWARNING! NEVER let metal, wire or other objects contact the inside of the display unit, or make incorrect contact with connectors on the rear panel. This could cause an electric shock or damage the display unit. RRWARNING! NEVER apply AC voltage to the DC connector of the display unit. This could cause a fire or damage the display unit. RRWARNING! NEVER apply more than 42 V DC to the DC connector of the display unit. This could cause a fire or damage the display unit. RRWARNING! NEVER touch or operate the display unit with wet hands. This could cause an electric shock or damage the display unit. RRWARNING! NEVER open the display unit. There are no user adjustment points. This could cause an electric shock and incorrect reassembly may cause a fire hazard. RRWARNING! NEVER operate the radar during a lightning storm. It may result in an electric shock, cause a fire or damage the display unit. Always disconnect the power source and scanner unit before a storm. RRWARNING! NEVER reverse the DC power cable polarity. This could cause a fire or damage the display unit. RRWARNING! NEVER remove the fuse holder on the DC power cable. Excessive current caused by a short could cause a fire or damage the display unit. CAUTION: DO NOT use or place the display unit in areas with temperature below -15˚C (+5˚F) or above +55˚C (+131˚F). CAUTION: DO NOT use harsh solvents such as Benzine or alcohol when cleaning, the display unit, as they will damage the display unit surfaces. CAUTION: DO NOT place the display unit in excessively dusty environments. DO NOT place the display unit near heating equipment or in direct sunlight or where hot or cold air blows directly onto it. DO NOT place the display unit in areas that could block air passage or put anything around the display unit. This will obstruct heat dissipation. KEEP the display unit out of the reach of unauthorized persons. KEEP the display unit away from heavy rain, and never immerse it in the water. The display unit meets IPX4 requirements for splash resistance when the supplied connection cable, scanner unit are connected. However, if it is dropped, splash resistance cannot be guaranteed because of possible damage to the case or the waterproof seals. iii The LCD display may have cosmetic imperfections that is displayed as small dark or light spots. This is not a malfunction or defect, but a normal characteristic of LCD display. DDFor Scanner unit: RRDANGER: HIGH VOLTAGE! NEVER open the scanner unit. The scanner unit contains high voltage that could be fatal. And there are no user adjustment points. All repairs and adjustments MUST be made by a qualified electronics technician at your Marine Navigation Dealer. DDFor qualified electronics technician only: RRDANGER: HIGH VOLTAGE! High voltages of up to 3,500 volts are used in the scanner unit. Although prudent measures for safety have been adopted, sufficient care must be taken in the operation, maintenance and adjustment of the scanner unit. Electric shock of 1,000 volts or more may cause electrocution and death, even an electric shock of only 100 volts may be fatal. RRDANGER: HIGH VOLTAGE! DO NOT turn OFF the radar's power and do not reach inside the scanner unit before you have: •• discharged the capacitors by disconnecting the system cable from the radar unit for 5 minutes. •• checked that no electric charges remain inside the device. Also, it is recommended to wear dry insulated rubber gloves. NEVER use both hands simultaneously, keep one hand in your pocket. RRWARNING: RADIATION HAZARD! Radiation emitted from the scanner unit can be harmful, particularly to your eyes. To avoid harmful radiation, turn OFF the radar's power before working on the scanner unit. DO NOT use or place the scanner unit in areas with temperature below -25˚C (-13˚F) or above +70˚C (+158˚F). NEVER immerse the scanner unit in the water. The scanner unit meets IPX6* requirements for highpressure water jet resistance. However, if the scanner unit is dropped, high-pressure water jet resistance cannot be guaranteed because of possible damage to the cases or the waterproof seals. * Except for the cable connectors. They meet IPX4 requirements while connecting to the scanner unit.
