NOTICE
The minimum DEEP ALARM setting can not
meet or go below the current SHALLOW ALARM
setting.
After your selection is made, the unit will return to nor-
mal operation after 5 seconds. The “DEEP” icon should
now be visible. See Figure E10.
Figure E10: “DEEP” Icon
If the depth of the water is greater than the selected
value, the alarm will sound and the icon will blink to
indicate the alarm. Pressing any button will mute the
alarm; pressing the SET will mute the alarm and acti-
vate the DEEP ALARM function for additional adjust-
ment. To permanently turn off, use the DOWN ARROW
to return the display to “OFF”.
4. Units
The UNITS Control function selects the UNITS of mea-
sure for depth readout and alarm functions. The three
settings available are Feet, Meters or Fathoms. See
Figure E11.

5. Keel Offset
The Keel Offset function adjusts the digital depth read-
out to display depth reading from either the waterline or
the keel (lowest point) of the boat, instead of from the
location of the transducer which is usually somewhere
in between. This permits optimum transducer location
and depth readouts suited to your needs.
To determine the value to enter into the KEEL OFFSET
setting, first decide whether depth from the waterline or
depth from the keel is desired. Measurements will
need to be made for the location desired.
For depth from the keel of the boat, accurately measure
the vertical distance between the face of the transducer
and the keel of the boat. This measurement will then be
entered into the Keel Offset function as a negative (-)
number. See Figure E13.
Figure E13: Negative Keel Offset
For depth measurements from the waterline, accurately
measure the vertical distance from the face of the trans-
ducer and the waterline of the boat. This measurement
will then be entered into the Keel Offset function as a
positive (+) number. See Figure E14.
