Perform monitoring while running as follows:
2.7.1 Confirmation of Alarm Status
1. Confirm that the alarm indicator lamp on the operation panel is off.
Note When a failure is activated in the system, the alarm indicator blinks and buzzes.
2. Confirm the alarm code displayed in the indicator.
3. Press ACK/ENT switch to stop buzzer.
Note If the alarm indicator lamp is still on after pressing the ACK/ENT switch, the failure continues.
Note If the failure is only momentarily, the alarm indicator lamp extinguishes at the same time the ACK/ENT
switch is pressed.
4. Take appropriate action according to Alarm on page 47 conditions.
2.7.2 Confirmation of Gyro Compass True Heading
1. Confirm that the Gyro Compass True Heading indicated in this system coincides with the heading by some target or
by observation.
2. Make corrections according to Confirmation of True Heading on page 44.
2.7.3 Confirmation of Latitude
• CAUTION - Confirmation of Latitude
• Change of the latitude input system or large change of the latitude may cause a large change of 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"
steering again.
• Confirm that the latitude value displayed on GPS coincides with the latitude value displayed on the indicator.
Note When "GPS" is selected as the latitude input system, the latitude obtained by GPS is displayed.
Note When "GYRO" is selected as the latitude input system and other than "MANUAL" is selected as the
ship's speed input system, the latitude is automatically updated.
• Confirm the displayed value every time when berthing (or at anchor) and in two hour intervals when GYRO has been
selected.
Note If there is a difference with the ship's actual latitude, set it again according to Set Latitude Input System
on page 40.
2.7.4 Confirmation of Ship Speed
• CAUTION - Confirmation of Ship Speed
• Change of the ship's speed input system or large change of the ship's speed may cause a large change of
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"
steering again.
The Gyro Compass generates an error due to the ship's speed. The system calculates this error and corrected True
Heading is sent out as repeater signal and serial signal.
1. Confirm that the ship's speed displayed coincides with the ship's actual speed at 2 hour intervals.
2. Set it again according to Set Ship Speed Input System on page 42, if there is a difference with the actual speed.
