Alarm Adjustment - Interphase Proble Operation Manual

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 either the up or down keys are
pressed and held down, or the large knob is rotated, a
vertical bar on the left side of the screen (just below the boat
icon) will move to show the area covered by the depth
alarm. In addition, a horizontal line will appear across the
display. 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. (Note: the horizontal line will disappear
a few seconds after the alarm is adjusted, however, the
vertical bar will remain)
The Shallow Alarm is often used to alert the user to
shallowing bottom conditions and the presence of
underwater targets such as fish, and when activated, will
sound a rapid beeping.
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. If the Deep alarm is
activated, the Probe will make a slow beeping noise.
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. When the Zone
Alarm is activated, the Probe will sound a medium speed
beeping.

Shallow or Deep Alarm.
