4.4 Using Alarms
The
ALARMS
key is used to set up alarms; three alarms are available to alert
you of fish, shallow water and deep water. Each alarm can be toggled
ON
and
OFF
, and you 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. Different buzzer tones are used to indicate fish detected by the
50 kHz and 200 kHz frequencies.
• 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 win-
dow 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 shal-
lower than the shallow alarm.
The top line status bar shows the condition of the alarms:
• indicates an alarm is enabled. The speaker symbol is unfilled until an
alarm is triggered and silenced, then the symbol is shown solid.
•
S
indicates the shallow alarm is enabled; a pop-up window indicates when
the alarm is triggered.
•
D
indicates the deep alarm is enabled; a pop-up window indicates when the
alarm is triggered.
• indicates the fish alarm is enabled.
External Alarms
All SeaTalk system alarms (except autopilot, shallow and deep) alarms are
received and displayed on the Fishfinder. You can silence these alarms by
pressing any key. No other action is taken by the Fishfinder except to silence
the alarm.
