Alarms
This unit has three different types alarms, Sonar, GPS and NMEA
2000. There are three Sonar alarms: Fish Alarm, Zone Alarm and
Depth Alarm.
The Fish Alarm will sound when the Fish I.D.
 feature determines an
echo is a fish. The Zone Alarm consists of a blue bar on the side of the
screen. Any echo on the chart that appears inside this bar triggers the
alarm. The Depth Alarm has both a Shallow and a Deep setting. Only
the bottom signal will trigger this alarm. It is most useful as an anchor
watch or shallow water alert.
Depth Alarms
The depth alarms sound a tone when the bottom signal goes shallower
than the shallow alarm's setting or deeper than the deep alarm's set-
ting. For example, if you set the shallow alarm to 10 feet, the alarm will
sound a tone if the bottom signal is less than 10 feet. It will continue to
sound until the bottom goes deeper than 10 feet.
The deep alarm works just the opposite. It sounds a warning tone if the
bottom depth goes deeper than the alarm's setting. Both depth alarms
work only off the digital bottom depth signals. No other targets will trip
these alarms. These alarms can be used at the same time or individually.
