7. CUSTOMIZING YOUR UNIT 

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 Cursor pad upward or downward to set appropriate value. 

 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). 

 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.   

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.
