3. Select item to adjust and press the EDIT soft key.
4. Use the cursor pad
to display appropriate value as below.
Speed and temperature calibrations: Enter plus or minus value. For
example, if the water temperature readout is 77
°
F but the actual water
temperature is 75
°
F, enter –2(
°
F).
Depth calibration: If you desire the depth readout to show the distance
between ship’s draft and bottom (rather than transducer and bottom), set
ship’s draft here. Enter a plus or minus value.
Acoustic speed calibration: Sets the speed of sound used by the network
sounder. Note that this is only used if water salinity is at an extreme level.
Under normal circumstances, do not adjust.
