Depth Pop-up and Depth Shallow Alarm
To warn of shallow water, a depth pop-up and shallow water alarm can
be configured in setup.
Depth Pop-up
When the depth is less than a pre-set value, the Depth page
automatically replaces the data item displayed in the lower
pane. The Depth page continues to be displayed until the
depth increases above the preset level, when the original lower
pane display is restored.

the alarm function. The alarm does not sound as the depth increases
above the preset level.
