Alarm Adjustment

In the forward looking display or view, alarms may be set
for targets which are shallower than, deeper than, or
within a specific zone of adjustable depth settings.
To adjust or clear the alarm settings, press the soft key
labeled "ALARM" to bring up the forward looking
Alarm menu choices. Pressing the "Deep" or "Shal." soft
keys brings up sub-menus to set, adjust or clear the
Shallow, Deep and Zone Alarms. As the up or down keys
are pressed and held down, a vertical bar on the left side
of the screen (just below the boat icon) shows the area
covered by the depth alarm with a horizontal line.
Whenever a solidly displayed target appears at the same
depth as that covered by the alarm bar, the audible alarm
sounds to warn you of underwater targets or changing
bottom conditions.
The Shallow Alarm is often used to alert the user to
shallowing bottom conditions and the presence of
underwater targets such as fish. The Deep Alarm is often
used in conjunction with the Shallow Alarm to define a
depth range. If the depth becomes less or greater than the
alarm settings, the audio alarm will sound as a warning.
A Zone Alarm can be created by using both the Shallow
and Deep Alarms. If the Shallow and the Deep alarm
bars on the left side of the display are "overlapped" (that
is the Shallow Alarm bar overlaps the Deep Alarm bar) a
new Zone Alarm will result and be displayed.
Press the "CLEAR" soft key to clear the alarm or alarms
you previously set. Press "CLEAR" in the main alarm
menu to clear all alarms simultaneously, or press
"CLEAR" in the sub-menus to clear the selected Shallow
or Deep Alarm.
