Safety contours
This function allows the user to display the depth areas cor-

OFF: no depth area displayed
Other values: the areas with depths up to the value selected
are displayed in shades going from darker blue (for lower depths)
to lighter blue (for higher depths). The areas whose depths
are over the limit set, and therefore navigable under safety
conditions, will be displayed in white.
Dryline areas are always displayed in green.
NOTE: In NIGHT mode, the areas with depths over the limit set, and therefore
navigable under safety conditions, are displayed in black.
