Use the Setup sub tab to turn DSC on and off. If you have more than 

one chartplotter and only want DSC to show on another chartplotter, 

turn DSC off on this unit.
This Setup sub tab also allows you to simulate distress calls and 

position reports while the unit is in Simulator Mode (see 

). 

Simulating calls is helpful for practice before connecting to the real 

system. The Distress Call simulator also helps to check if alarms are 

working properly.

more information about sonar setup options.

  NOTE: You must have a GSD 21 Sounder Module connected to 

your GPSMAP 378/478 to use sonar.
