NorthStar 6000i Quickstart Manual And Reference Manual page 30

If you zoom in still further, the 6000i
removes all chart detail from the screen for
safety reasons, leaving only your vessel, its
track, user-entered waypoints, and the
lat/lon grid.

Zooming in and out
Chart data doubled in size
Chart data removed from screen
As a reminder that no land, charted
hazards or nav aids are shown, the 6000i
faintly displays the words No Chart
multiple times across the screen. Even
without any chart data displayed, you can
still use the 6000i as a precision plotter.
NOTE:
Whenever the radar overlay is turned on,
the scales of the chart and the radar are
locked together so that the images will
line up. If you change the scale of one,
the scale of the other changes automati-
cally.
