Sensor setup

The sensor setup menu lets you further refine speed, temperature and depth
data fed from the network sounder.
1. Show the sounder display and press the [MENU] key.
2. Press the SOUNDER SYSTEM SETUP and SENSOR SETUP soft keys to
show the SENSOR SETUP menu. The current ship's speed, water
temperature, depth and speed of sound are shown at the bottom of the
menu.
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.
