6. MAINTENANCE AND INSPECTION The performance and longevity of this equipment depend on careful maintenance. To maintain the best performance, the following periodic inspections are highly recommended. (1) Keep the power supply voltage within the specified value (19-35Vdc). (2) Know the condition of normal status when the equipment is properly functioning. Keep comparing the current status to the normal status to immediately detect any malfunctions.
6.2 Periodic Inspection 6.2.1 Confirming the Own Ship’s Information Displays own ship’s detail information and confirm that the static (ship name, MMSI etc.) and dynamic (position, heading etc.) information is correct. In order to display the Own Ship’s Detail Information, Press DISP key several times and the screens are changed by each key press. Own Ship’s Detail Information is composed of 2 screens. 1 9 / 0 , + % 0 / # 4 / # Ť 5 / % 1 . 5 * + + ' / 0 1 . 5 2 5 & ' 6 # + .
