Sonar Alarms
CAUTION:
The Safe Depth and Safe Height settings influence
how the chartplotter calculates an Auto Guidance line. If an area
has an unknown water depth or an unknown obstacle height, the
Auto Guidance line is not calculated in that area. If an area at the
beginning or the end of an Auto Guidance line is shallower than
the safe water depth or lower than the safe obstacle height, the
Auto Guidance line is not calculated in that area. On the chart,
the course through those areas appears as a gray line. When your
boat enters one of those areas, a message appears.
