follows:
• If Plotter Mode is Off, the chart scale remains unchanged, indicating

• If Plotter Mode is On, the scale is decreased and the message NO CHART
DATA is displayed. The vessel, waypoints, routes and tracklines are dis-
played without cartography.
The chart information is restored when you return to a chart scale for which the
information is available.
