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.
