The DSC page of the Main Menu allows you to control and 

set up the Digital Selective Calling (DSC) features on the 

GPSMAP 192C. 
Digital Selective Calling (DSC) uses marine VHF radio and 

Global Positioning System (GPS) technologies to transmit and 

receive location information. The chartplotter repeats the call 

properties received from the VHF radio on the chartplotter. The 

GPSMAP 192C requires input from a DSC enabled VHF radio to 

display position, and sound/display alerts from a Distress Call or 

Position Report. Conversely, the VHF radio requires input from a 

GPS to transmit position coordinates for a Distress Call or Position 

Report. For connection information, please refer to “Connecting 

the Power and Data” on page 

An emergency DSC Distress Call allows a vessel in trouble 

to transmit a substantial amount of information in a single 

transmission or call, without the need for voice communication. 

When any nearby rescuer receives the DSC signal, an alarm sounds 

and they immediately receive the location of the caller. The rescuer 

can then choose to navigate to the caller’s location to assist, or 

forward the call on to the Coast Guard. When the Coast Guard 

receives the call, they can immediately access the caller’s 

information (such as who they are and the type of vessel) in their 

database while they are in transit to the caller’s location.
A non-emergency DSC Position Report allows mariners to 

exchange and display the positions of one another. When a DSC 

position is received, the mariner can choose to create a waypoint or 

to show the received location on an electronic map. 
Anytime a vessel receives a DSC call, they can store and quickly 

navigate to that location using a Go To. This makes DSC a time 

saver, especially in an emergency situation. In order to use DSC, 

users must first register their VHF radio with the FCC and receive a 

Maritime Mobile Service Identity (MMSI) number. 
For more information about Digital Selective Calling and Maritime 

Mobile Service Identity (MMSI) numbers, refer to page 

103

 in the 

“Appendix.”

When the GPSMAP 192C receives a Distress Call from a 

connected DSC enabled VHF radio, an alert message and 

notification page are displayed, and an alarm tone is sounded. 

Distress Calls are shown in the DSC Call List, and Log with a 

checkered symbol.
