4. When no further chart detail is available, as you press the bottom of
the RANGE key, the effect depends on whether Plotter Mode is on
or off as follows:
• If Plotter Mode is Off, the unit beeps three times and the chart scale
remains unchanged, indicating the smallest chart scale is displayed.
• If Plotter Mode is On, the scale is decreased and the message “NO
CHART DATA” is displayed. The vessel, waypoints, routes and
tracklines are displayed without cartography.
The chart information is restored when you return to a chart scale for
which the information is available.
➤ To zoom out to a smaller-scale (less detailed) chart, simply press the
upper part of the RANGE key as many times as required.
