Sensor setup

The SENSOR SETUP menu lets you further refine speed, water temperature
and depth data fed from the network sounder.
1. Show the sounder display, then 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, then press the EDIT soft key.
4. Adjust the trackball upward or downward to set appropriate value.
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. Normally no adjustment is required, however if echoes are returning
too slow or too fast adjust the value as appropriate. This is only used if water
salinity is at an extreme level. Under normal circumstances, do not adjust.
