Chapter 4: Setting Up the Chartplotter 4-7
Orientation
The chart orientation is normally North Up, but can be changed to Course Up or
Head Up. The orientation modes give the following displays:
• 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 whilst Course Up is the current mode, re-
select COURSE UP from the set up menu.
If you select a new course, eg. a new target waypoint, 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.
Show waypoints
This option controls whether or not the waypoints are shown on the Chart
display, with their appropriate symbols. The active waypoint, and waypoints in
the current route, are always shown.
Waypoint symbol
This option allows selection of the symbol for waypoint display. The selected
symbol is used for subsequent waypoints. Existing waypoints are not affected.
The selected symbol is retained when the unit switched off.
Autozoom
When autozoom is enabled, commencing any navigation function or selecting
FIND SHIP activates Autozoom. When active, this selects the chart range and
position such that the vessel and the target waypoint are both on screen but at
the largest scale possible. Moving the cursor off the vessel, or changing scale,
deactivates Autozoom.
