Equipment Operation
In theory the depth gauge picks up a bottom signal sent
through a transducer to the helm gauge unit which is con-
verted to readings in feet, meters, or fathoms and displayed
on the gauge. The unit features shallow or deep water
alarms, both of the audio and visual type, and keel offset.
General Description.
The sounder will display depths of 2-199 feet, 1-92 meters,
or 1-54 fathoms. To accommodate greater depths to be
displayed in the “ft” feet mode the depth sounder will
automatically change to “F” fathoms mode and continue
to display depths to around 54 fathoms.
When the depth decreases below 200 feet the display will
return to the “ft” mode. Limits on depth will vary depend-
ing on transducers and bottom conditions.
If the reading is less than 19.9 feet, meters, or fathoms, 1/
10th increments will be displayed. If the reading is more
than 19.9 feet, all readings will be in whole numbers.
The depth sounder features an audible and LCD displayed
depth alarm with adjustable shallow and deep limits and a
depth below keel offset feature. These settings once made
are stored in memory and will remain even if the battery is
not connected.
OPERATION
Power On. When the helm is powered up by the key switch
12 volt DC energy is available at the depth gauge along
with the remainder of the instrument cluster. You do not
need to press the “ON/OFF MODE” keypad.
The LCD will illuminate showing the depth and the type
of units selected; feet (FT), meters (M), or fathoms (F). To
deactivate the depth sounder, hold the “ON/OFF
MODE” keypad for 4 seconds. If you press the “ON/
OFF MODE keypad again the unit will be reactivated.
Depth Alarm. Shallow mode: If you press the “ON/OFF”
MODE” keypad again the “SH” shallow depth alarm set-
ting is displayed. This is the shallowest water that will en-
ergize the alarm. Press and hold the up or down arrow
keypads to adjust the reading to the desired depth.
Depth Alarm. Deep Mode: By pressing the “ON/OFF
MODE” keypad displays again the “DP” deep depth alarm
setting. This is the deepest water that will energize the
alarm.
Press and hold the “UP” or “DOWN” keypads to adjust
the reading to the desired depth. When the shallow depth
setting is read by the depth sounder, the “SH” will flash
on the LCD and the audible alarm will sound in a rapid
sequence. When the deep depth setting is read by the depth
sounder the “DP” will flash on the LCD and the audible
alarm will sound at 2 beeps per second.
Note: To fully deactivate the alarm, reset it to zero. Press-
ing the “ON/OFF MODE” keypad temporarily deacti-
vates the alarm. To reactivate the alarm press the “ON/
OFF MODE” keypad until the depth reading appears.
