Three types of presentation modes are provided for the
plotter display
: north-up, course-up, and auto course-up.
To change the presentation mode, press the [HIDE/SHOW] key followed by the MODE soft key.
Each press of the key changes the presentation mode and presentation mode indication (top right-hand corner of the screen) cyclically in the sequence of
North-up, Course-up, and Auto course-up.
North-up
North (zero degree) is at the top of the display and
ownship is shown with a filled circle. This mode is
useful for long-range navigation.
Course-up
The course-up mode is useful for monitoring ship’s
progress towards a waypoint. The destination is at
the top of the screen when a destination is set.
When no destination is set, the course or heading is
at the top of the screen at the moment the course-
up mode is selected. A filled triangle marks
ownship’s position.
Auto Course-up
The course is at the top of screen at the moment the
auto course-up mode is selected. In this mode, the
current course is kept at the top of the screen when
the change is within 22.5 degrees. For example, if
your vessel turns larger than 22.5 degrees to port or
starboard, the chart display will rotate so that your
course is pointing towards the top of the screen
again. A filled triangle marks ownship’s position.
