Setup > Chart - NorthStar Explorer 660 Installation And Operation Manual

15-2 Setup > Chart
Press MENU once or more until the Setup menu
is displayed, then select Chart:
Rotation
The options for chart rotation are:
North up: North is always at the top of the
chart display.
Track up: The chart is rotated so that the
boat direction is to the top of the display.
This option is useful for navigating narrow
harbours or rivers. The Explorer 660 asks for a
course deviation; this is how much the boat
direction needs to change to make the chart
redraw.
Tip: If the chart redraws too
frequently, increase the course deviation
setting.
Course up: This option is only available if
the boat is navigating to a destination. The
chart is rotated so that the plotted course to
the destination is vertical.

Projected course
The Explorer 660 can estimate the course after
a given time, based on the current speed and
heading (see section 3-5). The options are 2
minutes, 10 minutes, 30 minutes, 1 hour, 2 hours
or Off.
CDI Scale
The CDI Scale is described in Appendix C, CDI.
The options are 0.05, 0.1, 0.2, 0.5, 1.0, 2.0, 4.0 and
10.0 distance units.
Plotter mode
Occasionally it is desirable to use a chart scale
which is not available on a chart card. Examples
are:
To zoom in to a small scale to track very small
boat movements.
If there is no detailed chart for an area, for
example when crossing an ocean.
If Plotter mode is On, then if the chart zooms
to a scale which is not available, the Explorer
660 will enter plotter mode and will only display
the boat position and track (if enabled). Chart
information will no longer be displayed and the
display is white with black crosshatch lines.
For normal use, turn Plotter mode to Off.
Mixing levels
Mixes lower detail charts with higher detail charts
on chart boundaries.
: Lower detail chart is not shown.
