RANGE key, the result depends upon whether Plotter Mode is on or off :
• 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. 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, press the top of the

RANGE key as many times as required.

2.5 Using Navionics Nav-Chart cards

The chartplotter has a built-in world map that can be used for route planning.
Most areas (these are shown with chart box boundaries) are covered at a range
of approximately 64nm as shown on the Status Bar at the top of the screen.
Note: To ensure maximum detail for the built-in world map, two versions are
available covering the Americas and the Rest of the World.
To use the chartplotter as a navigation aid, charts with detailed information for
the area you wish to navigate are required. The charts are available on
Navionics Nav-Chart cards, each of which can store as many as 20 charts in an
electronic format, depending upon its memory storage capacity.
A Nav-Chart card provides an appropriate level of detail for a given geographic
area and scale; this data can be displayed down to a range of
(height) if the data is available.
