indicates the orientation.

Zooming In and Out of the Map
The map display has 28 available zoom ranges from 20 ft to 800 nm
(20 ft to 800 mi or 5 m to 1200 km). The map scale is controlled by
the IN and OUT keys, with the current scale shown at the bottom
right of the data window.
NOTE: The scale value represents the distance from one end of
the scale bar ( ) to the other.
To select a map scale (zoom in and out):
Press the OUT key to zoom out, press the IN key to zoom in.
The system has a built-in worldwide database, with more detailed
coverage available through the use of the BlueChart or MapSource
data. The GPSMAP 276C shows cartography as long as chart
information is available for the zoom scale you selected.
Map coverage conforms to the following conditions:
• Cartography is shown when the selected zoom range is
covered by either the internal basemap or other MapSource
data loaded onto a data card.
• When the selected zoom range is covered by both the internal
database and data card map information, the cartography with
the best resolution appears.
