Changing the Chart Scale
The RANGE key allows you to change the chart scale so that you can see a
smaller or larger area on the screen.
Plotter mode is available to allow you to zoom into a smaller area, even when
no chart data is available for that scale. Section 7.5 describes how to set plotter
mode on/off.
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)
on the screen.
• To move the display to another area of the chart, by zooming out to a small
scale chart, then zooming in on another position centered on the cursor.
Each time you press the RANGE key, the chart scale changes to the next
available setting. The status bar indicates the distance from top to bottom of
the screen, in nautical miles.
RANGE
To change the scale quickly, press and hold the required arrow on the RANGE
key.
RANGE
The distance indicator at the left-hand end of the status bar is updated
whenever you change the chart scale.
To zoom in to a larger-scale (more detailed) chart:
1. Use the trackpad to position the cursor in the area you wish to see in more
detail.
2. Press the lower part of the RANGE key to zoom into the area.
The section of the chart around the cursor is enlarged to fill the screen with
a larger-scale chart showing more detail. The cursor is now positioned in
RANGE
the center of the screen.
The distance indicated at the top left of the screen is updated.
3. If further chart enlargement is available using the current chart card you
can press the bottom of the RANGE key to zoom in again, re-positioning
the cursor first if required.
An area of further chart detail is indicated by a box around the area as
shown in Figure 3-11.
