Changing the Chart Scale
The
RANGE
key changes the chart scale so that a smaller or larger area is
shown on the available cartography.
Plotter mode is available to allow you to zoom into a smaller area, even
when no chart data is available for that scale. To enable plotter mode, see
Chapter 4: Setting Up.
You can change the chart scale for two purposes:
• To see either more detail (of a smaller area) or a larger area (in less
detail).
• To move the display to another area of the chart, by zooming out to a
small scale chart, then zooming in on another position.
Each time you press the
RANGE
key, the chart scale changes to the next
available setting. The Status Bar at the top of the screen indicates the
distance, from top to bottom of the display, in nautical miles (Figure 2-5).

whenever you change the chart scale.

To zoom in to a more detailed chart:
1. Use the trackpad to position the cursor in the area you wish to see in
more detail and press the bottom of the
RANGE
key to zoom in.
The section of the chart around the cursor is enlarged to fill the screen
with the chart showing more detail. The cursor is now positioned in
the centre of the screen.
The distance indicated at the top left of the screen is updated.
