Using Alarms
The ALARMS Functionbar button is used to set up alarms: three
alarms are available to alert you to the presence of fish, shallow water,
and deep water. Each alarm can be toggled On/Off, and you can set
the depth at which shallow and deep water alarms are triggered
(between the ranges 2–3000 feet/0.5–500 fathoms/1–1000 meters).
You may want to use the shallow and deep water alarms when you are
anchored. Set the limits to just above and below your anchor depth;
the Fishfinder triggers an alarm if the anchor drags and the boats
moves into shallower or deeper water.
• Fish Alarm – If this alarm is On, the unit sounds a buzzer
whenever it finds a fish.
• Shallow water – You set depth at which the shallow water
alarm triggers. When the depth is less than that set, the
buzzer sounds and a pop-up window describing the alarm
is displayed. You cannot set the shallow alarm to be
deeper than the deep alarm.
• Deep water – You set depth at which the deep water alarm
triggers. When the depth is more than that set, the buzzer
sounds and a pop-up window describing the alarm is
displayed. You cannot set the deep alarm to be shallower
than the shallow alarm.
