II.1 Warning Label The following warning label is attached to this system. II.2 Location Warning Label The warning label is attached to the inside of the door of the Control Panel.
  • Page 8 • WARNING - Inverter Failure (alarm code 3) • When checking fuses, turn "OFF" the power switch on the operating panel and disconnect the power cable from the ship’s Distribution Terminal Board. • WARNING • When checking fuses, turn "OFF" the power switch, and further disconnect the power cable from the ship’s distribution terminal board.
  • Page 9 • CAUTION - Setting Latitude Input • When "GYRO" is selected for the latitude input system, latitude is automatically updated by the ship's speed and the Gyro Compass True Heading. (When the ship's speed input system is "MANUAL", it is not updated automatically.) During navigation, confirm once every two hours that the ship's actual latitude coincides with the indicated latitude.
  • Page 10 • Change of the ship's Speed Input System and the Latitude Input System, or large change of the ship's speed and latitude, may cause a large change of the Gyro Compass True Heading. When on automatic steering, first turn the steering mode of the automatic steering system to "MANUAL" to prevent a large course change. Confirm the area around the ship is clear and turn to "AUTO"...
