USE OF NAVIGATION TOOLS
The system is equipped with the navigation tools as below.
Cursor
Specifies an arbitrary point, and measures the range and bearing from the own ship.
Range Rings
Displays concentric circles with own ship's position as the center at specified intervals, and the rings are
used as rough guides for range measurement.
Electronic Bearing Line (EBL1/2)
Displays a straight line for specifying an arbitrary bearing, and measures the bearing from the own ship.
The processing unit is equipped with two electronic bearing lines.
Variable Range Marker (VRM1/2)
Displays a circle for specifying an arbitrary range, and measures the range from the own ship.
The processing unit is equipped with two variable range markers.
Parallel Index Line (PI)
Displays straight lines at even intervals, and the lines are used as rough guides for complex measurement
or ship courses.
EBL Maneuver
Displays the course by steering the own ship, and it is used as a rough guide for ship maneuvering.
Man Overboard
Stores the latitude and longitude where the own ship was at the point of storing the markers, and shows
an anchor symbol on the radar display. When the own ship has moved, the system displays the range and
bearing to the position.
Use this tool when the ship is anchored or man overboard.
