2.5.3 Set Start Heading
After the software version number is displayed, in cases without timer start function, or after departure date and time is shown
in cases with timer start function, the display shows "start heading input", as shown below.
Set Start Heading:
1.
Press switch
▲,
or
▼.
2.
Press switch
ACK/ENT
to confirm.
The display indicates the Gyro Compass True Heading and the Master Compass turns to the entered heading.
Note
When the system starts from the heading when the last azimuth operation was completed, setting
of the "start heading" is not necessary, but pressing ACK/ENT switch is. If not pressed, this system
automatically proceeds to the next sequence after 3 minutes.
2.5.4 Confirming Latitude Input
•
CAUTION - Setting Latitude Input
Change of the latitude input system, or a large change of latitude value may cause a large change in the
True Heading. When on automatic steering, first turn the steering mode of the automatic steering system
to "MANUAL" to prevent a large change of course. Confirm the area around the ship is clear and turn to
"AUTO" steering again.
•
CAUTION - Setting Latitude Input
•
When an alarm regarding GPS (alarm code "c" or "d") is activated and the Gyro Compass' True Heading has
not been determined, first turn the steering mode to "MANUAL", or "Non Follow Up", then determine the
True Heading, because wrong heading information (repeater signal and serial signal) may be sent out.
•
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.
1.
