2.3 How to Select the ECDIS Operating Mode
The ECDIS has three operating modes: Voyage navigation, Chart maintenance, and
Voyage planning. Select the mode from the Status bar with the [PLAN], [CHARTS]
and [NAVI] buttons. The background of the button of the active mode is blue.
Note 1: When switching between the Voyage navigation and Chart maintenance
modes it may take several minutes to read the chart database when using C-MAP
charts or there are many charts installed.
Note 2: If the equipment accepts no key operation after switching to the Chart main-
tenance mode, reset the power.
2.4 How to Select the Chart Scale
When you open a chart it is displayed with the default scale, called the compilation
scale. To change the chart scale, do one of the procedures shown below. The scale
range is 1:1,000 to 1:70,000,000.
• Click the chart scale selection buttons in the Chart scale/presentation mode box.
• Right-click anywhere inside the Chart scale/presentation mode to show a drop-
down list of chart scales.
• Put the cursor anywhere on the chart and spin the scrollwheel.
Note: When the radar overlay is active the chart scale is shown in nautical miles (NM).
