Page 26

An area of further chart detail is indicated by a box around the area as shown in the following illustration.

If further chart enlargement is available using the current chart card you can press the bottom of the RANGE key to zoom in again, repositioning the cursor first if required.

The distance indicated at the top left of the screen is updated.

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 the centre of the screen.

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 into the area.

The distance indicator at the left-hand end of the status bar is updated whenever you change the chart scale.

For rapid scale change, press and hold the required arrow on the RANGE key.

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. To enable plotter mode, see Chapter 4, Setting Up the Chartplotter.

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.
