Chapter 7
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 dis-
played on the gauge. The unit features shallow or deep
water alarms, both of the audio and visual type, and keel
offset.
General Description.
The optional depth finder 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 fath-
oms.
When the depth decreases below 200 feet the display will
return to the “ft” mode. Limits on depth will vary de-
pending 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 finder 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.
DEPTH GAUGE W/ FUNCTIONS
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 setting is displayed. This is the shallowest water
that will energize 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 finder, the “SH” will flash on
the LCD and the audible alarm will sound in a rapid se-
quence. When the deep depth setting is read by the depth
finder 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.
