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 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. 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 any of the sub-menus to clear the selected
Shallow or Deep Alarm.
