6.3 Using Alarms
Three
ALARMS
are available to alert you of fish, shallow water, and deep
water. Each alarm can be toggled
ON
and
OFF
independently. For the shallow
and deep water alarms, you set the depth at which the alarms are triggered,
ranging from 2–3000 feet (or 2–4900 feet for units high performance
transducers).
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.
Note: The Deep Alarm must be set at a depth that is greater than the depth at
which the Shallow Alarm is set. Conversely, the Shallow Alarm must be set at
a depth that is less than the depth at which the Deep Alarm is set.
After you have acknowledged the sounding of a shallow or deep water alarm,
a minimum of 30 seconds must elapse before a another shallow/deep alarm
can sound again.
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.
