68 DS400 and DS500 Digital Fishfinders
Note: 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. However, the visual indicator will continue as long
as the condition exists.
Target Depth ID
You can select whether the depth or a fish icon is shown for sonar echoes
displayed on the screen. The default setting is OFF.
• OFF displays neither the depth or a fish icon.
• DEPTH displays the depth just above each fish echo.
• FISH displays a fish icon in place of each echo.
• FISH & DEPTH displays both the depth and a fish icon.
Fish Alarm
If this alarm is ON, the unit sounds a beeper whenever it finds a fish. The
default setting is OFF.
Shallow Alarm
If this alarm is ON and the depth below the boat is less than the value set using
the Shallow Range setting, the beeper sounds and moving arrow indicators
point to the digital depth display. You cannot set the shallow alarm to be
deeper than the deep alarm. The default setting is OFF.
Shallow Range
Use the < and > trackpad keys to decrement/increment the depth at which the
Shallow Alarm will sound. The depth units are dependent on the value set
using the UNITS... parameter. (See page 71.) Changing the value set for
Shallow Range automatically enables the Shallow Alarm.
Deep Alarm
If this alarm is ON and the depth below the boat is greater than the value set
using the Deep Range setting, the beeper sounds and moving arrow
indicators point to the digital depth display. You cannot set the deep alarm to
be shallower than the shallow alarm. The default setting is OFF.
