Temporary chart priority display control

The chart radar mode displays both the radar echo and chart symbols, with the radar echo having priority. If the
chart symbols become hidden in the radar picture, do one of the following to give temporary priority to the chart
symbols.
Chart priority
In the chart radar mode, select the Chart Priority box (bottom left-hand corner) and push and hold down the left
mouse button to give priority to the chart symbols (coastline, depth contours, navigation buoys, etc.). Release the
button to restore priority to the radar echo.
Coast line only
In the chart radar mode, select the Coast Line Only box (bottom left-hand corner) and hold down the left mouse
button to temporarily erase chart symbols and show the coastline together with radar echo, which has priority.
Release the button to show the chart symbols.

Chart status box

If, in the ECDIS mode, there is something wrong with a chart, a "permanent message for S57 charts" appears. For
details see section 7.1.3 Permanent messages for S57 charts.
For the chart radar mode, a "permanent message" cannot be displayed automatically. In this mode, when something
is wrong with a chart, the Chart Status box appears. Click the box to show the permanent message in the data
display area.

Chart alert function

The chart alert function operates in both the chart radar mode and the ECDIS mode. There are two types of chart
alerts: your ship's predicted course, and route alert. For details see Chapter 9 Chart Alerts.
For the ship's predicted course alert, the operator sets a safety contour (see section 9.1.1 How to select safety
contour) to select safety depth suitable for the ship. The operator also sets the parameters for own ship predicted
movement (see section 9.3 How to Activate Own Ship Check).
For the route alert, route planning (see section 9.4 Route Planning) and route monitoring (see section 9.5 Route
Monitoring) functions are available.
Note that if you change from "chart radar" mode or "ECDIS" to "radar" mode, the chart alert feature is automatically
switched off by the system.
