Chapter 3: Getting Started 27
• When the vessel moves near the edge of the chart window, the chart
is redrawn with the vessel at the center and the cursor homed on the
vessel.
• While homed, the status bar indicates position, SOG and COG.
• If SCREEN AMPLIFIER is enabled, the screen displays the vessel off-
set from center, to increase forward visibility, see Chapter 4:Setting
Up.
3. To release the cursor from homed mode press the trackpad to move
the cursor away from the vessel’s current position. The status bar
shows the cursor position, range and bearing from the vessel.
Changing the Chart Scale
The RANGE IN/OUT keys change the chart scale so that a larger or
smaller 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 a smaller area (in more detail) 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 to another location
Each time you press the RANGE IN or RANGE OUT keys, the chart scale
changes to the next available setting. The Status Bar at the top left-hand
side of the screen indicates the distance, from top to bottom of the display,
in nautical miles.
