40 RC435 and RC435i Chartplotters
Orientation
The chart orientation is normally North Up, but can be changed to Course
Up or Head Up. The selected mode is always shown in the inverse video
Mode Indicator in the top left hand corner of the Status Bar at the top of
the display in the form NU (North Up), HU (Heading Up) or CU (Course
Up). The orientation modes function as follows:
• North Up: The chart is displayed with north upwards. This is the
default mode and is the only mode available if there is no COG data.
• Course Up: The chart is rotated such that the currently selected
course (bearing to the target waypoint) or, if no navigation function is
taking place, the current COG value is shown upwards.
To update the Course Up reference while Course Up is the current
mode, re-select COURSE UP from the set up menu.
If a new course is selected (a new target waypoint, for example), the
chart displays the new course upwards.
• Head Up: The chart is displayed with the vessel’s current COG
upwards. As the heading changes the chart rotates periodically to
maintain orientation.
Note: Head Up and Course Up modes are dependent upon a valid GPS
fix.
Plotter Mode
Plotter mode allows the user to zoom in beyond the level of cartography
and continue to use plotter functions. The selected setting is retained
when unit switched off.
