Sonar Alarms
CAUTION: The Safe Depth and Safe Height settings inuence
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.
Shallow Water/Deep Water—allows you to set an alarm to sound
when you enter an area of water that is too shallow or deep. Select On,
and then specify a depth. You must be receiving sonar NMEA data for

Water Temp—allows you to set an alarm to indicate if the water
temperature has exceeded or dropped below a specic temperature,
or fallen outside/inside a specic temperature range. Select Above
or Below, and then enter a specic temperature, or select Inside or
Outside and enter a range of temperatures. You must be receiving
sonar NMEA data for this function to work.
Drift—allows you to set an alarm to sound when you exceed a
specied drift distance. Select On, and then enter a specic distance.
