pear in a paler shade of grey. Those that disappear are con-
tours which appear on the chart as discontinuous or "open."
Those contours that remain, displayed in lighter grey, are
closed contours, (i.e. forming a closed shape). Closed-con-
tour lines cannot be turned off.
Depth Areas Limits
Areas within closed depth contours are called depth areas.
Depth areas can be shaded using the Depth Areas Limits set-
ting under Map Configuration, Marine Settings. This shad-
ing gives you an instant visual cue on the chart when you
approach the depth areas limit you have selected. When you
set a depth area limit to a certain value, all areas shallower
than this value will be shaded. Depth areas deeper than the
selected value will remain unshaded.
The exact value you set as the Depth Area Limit may not be
on a contour, as contours occur at varying intervals. Conse-
quently, when you choose a depth value, the receiver defaults
to the next deepest depth area limit available. For example, if
the value you enter is 15 feet, and the adjacent closed depth
contours are at 10 and 20 feet, the receiver defaults to 20 feet
such that all area within this contour, (i.e. shallower than 20
feet), is shaded.
To set the Depth Areas Limits, press Aux, select Map Con-
figuration and press ENTER. Highlight Marine Settings and
