Heading

For C UP (Course up mode)

When choosing Course up mode, current heading becomes the course at the top of the display and a

moving heading line indicates actual.

This mode is used to navigate towards a specified course.

It easily shows any deviation of own ship from the specified course.

Note:

・This is an azimuth-stabilized presentation in which the bearing scale can be oriented so that own

ship’s course on the bearing scale is vertically above the own ship.

・The heading line points from the own ship to own ship’s referenced heading on the bearing scale.

・If own ship’s heading differs from the course, then the heading line does not point vertically upwards

from the own ship until the bearing scale is reset (manually or automatically) to reflect the course

alteration.

For N UP (North up mode)

This mode always keeps true north at the top of the display.

A north oriented representation makes it easy to reference with a chart.

Note:

・ This is an azimuth-stabilized presentation in which north on the bearing scale remains fixed vertically

above the own ship.

・ The heading line points from the own ship to own ship’s referenced heading on the bearing scale.

・ The true bearing of any target on the display is measured from north.
