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 disconnected.
Operation:
1. Power on. The depth sounder will activate
automatically when the power to it is initially
turned on. You do not have to press any key.
The LCD will illuminate showing the depth
in the upper display. The lower display will
show a “W” and water temperature.
Press the “Up” switch and the lower display
will change to an “A” and the air temperature
will be displayed.
Press the “Down” switch to return to the
water temperature display.To turn the depth
sounder off, press and hold the “Mode”
switch for 4 seconds. Pressing the “Mode”
switch again will reactivate the unit.
NOTE: The instrument is designed to have
the internal LED lighting remain on as long
as power is supplied even if the unit is turned
“off” by the “Mode” switch.
2. Depth alarm.
Deep mode: Pressing the “Mode” switch
again displays the “DEEP”, deep depth alarm
setting. This is the deepest water that will
activate the alarm. Press and hold the “Up”
or the “Down” switch to adjust the reading to
the desired depth.
Shallow mode: Press the “Mode” switch to
display the “SHAL”, shallow depth alarm
setting. This is the shallowest water that will
activate the alarm. Press and hold the “Up”
or the “Down” switch to adjust the reading
to the desired depth.
When the depth of the water is less than
the shallow depth alarm setting the audible
alarm will sound rapidly. When the depth
of the water is deeper than the deep depth
alarm setting the audible alarm will sound at
2 beeps per second.
NOTE: To fully deactivate an alarm, reset it to
zero. Pressing the “Mode” switch temporarily
deactivates the alarm. To reactivate the alarm
press the “Mode” switch until the depth
reading appears.
3. Keel offset. Pressing the “Mode” switch
again displays the “KEEL,” keel offset
setting. This can be set so that the depth
sounder either shows the depth below the
keel or the depth below the transducer.
Press the up or down arrow switches to adjust
the reading to the desired depth no more than
19.9 ft.
For example if the bottom of the keel is 2.5
feet below the transducer and you want the
depth sounder to read the depth below the
keel, the display should be adjusted to read
2.5 FT.
NOTE: Once a keel offset is programmed,
the shallow and deep alarms will be activated
by the depth below the keel.
Units:
Change the unit of measure. The lower
display will show “UNIT” and the upper
display will show either “US” or “EURO”
for metric units. Pressing the up or down
switches will cycle through the choices.
Pressing the “Mode” switch will save the
units shown in the display and change the
display
Back to the normal depth mode. There will
be no units shown in the displays. It will be
up to the operator to determine the units from
the temperature reading.
