The deep alarm can be set anywhere within its typical
range of 6-120 ft.
Move the DISPLAY switch from the down DEPTH
position to the up ALARM SET position. The LCD
readout will now indicate the depth to which the deep
alarm is set.
Slowly rotate the deep alarm knob to reduce the depth to
which the alarm is set. As the knob is rotated, the
number displayed on the LCD readout reduces. Adjust
this knob to the desired alarm depth as indicated on the
LCD readout. Once the deep alarm has been set, return
the DISPLAY switch down to the DEPTH position to
resume reading the water depth on the LCD readout.
10. USE THE DEEP ALARM & ANCHOR ALARM
The deep alarm can be used by itself to warn you of
sudden drop-offs in bottom contour, or it can be used in
conjunction with the shallow alarm to serve as an anchor
guard. For example, to anchor the boat in a harbor
where depth varies from 20 to 24 ft. due to the tide, it is
possible to set the alarms to sound it the anchor drags
and the boat drifts either too close to shore or out into
deeper water.
SEPARATELY set the shallow alarm to 18 ft. and the
deep alarm to 26 ft., then turn them both on
simultaneously. This set-up allows the alarms to tolerate
a four ft. tide and a four ft. sea. If the anchor drags and
the boat drifts into water that is too shallow, or too deep,
an early warning is provided. This simultaneous alarm
function can also be used to follow a contour line on your
chart. Simply adjust the shallow alarm two to four ft.
shallower than the contour line and the deep alarm two
or four ft. deeper than the contour.
The deep alarm will also sound whenever "No Echo" is
being received, making it an audible "No Echo" indicator.
