Press the right arrow key, then the up or
down arrow keys until 1.0 appears in the
"Adj Keel" box, as shown at right, then press
the ENT key. This immediately changes the
digital depth display at the top of the screen
by one foot. Press the EXIT key to erase this
menu.
Note: Another way to use the keel offset
feature is if you want to know the depth of
the water below the lowest part of the boat,
instead of the surface. To do this, measure the lowest part of the boat below
the transducer. In this example, we'll use 3 feet. Now, using the keel offset
feature, adjust the offset for a
negative
3 feet.
Please note that adjusting the keel offset only affects the digital depth
display and all features that use the digital depth, such as the depth alarms
and FishTrack. This doesn't affect the chart at all.
Calibrate Speed
You can calibrate the speed display if an
optional speed sensor is attached. To do
this, highlight the "Calibrate Speed" label on
the "System Setup" menu, then press the
right arrow key. A screen similar to the one
at right appears.
If the digital speed display is slower than
your actual speed, add a positive percent-
age to make it read faster. If the digital speed
display is faster, use a negative percentage
to make it read slower. Use the arrow keys to change the speed, then press
the ENT key. Press the EXIT key to erase this menu.
Simulator
This unit has a simulator built in that lets you use it as if you are on the water.
All features and functions of the unit are usable. A message appears
occasionally to remind you that the simulator is on.
To use the simulator, press the MENU key, then press the up or down
arrow keys until the "System Setup" menu appears. When it does, press
the right arrow key. Now press the up or down arrow keys until the
"Simulator" label is highlighted. Finally, press the right arrow key. The unit
returns with both simulated digital data and chart echoes.
