DSC Tab—
allows you to control the optional Digital Selective Calling (DSC) interface. Digital Selective
Calling (DSC) uses marine VHF radio and Global Positioning System (GPS) technologies to transmit and
receive location information. DSC is used by mariners to assist them in two major areas: Distress Calls and
Position Reporting.
An emergency DSC Distress Call allows a vessel in trouble to transmit a substantial amount of infor-
mation 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 position of the caller.
The rescuer may then choose to navigate (Go To) the caller’s position 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 posi-
tion.
A non-emergency DSC Position Report allows mariners to exchange and display the positions of one
another. Once a DSC position is received, the mariner may choose to create a waypoint or to show the
received position on an electronic map.
The track name automatically appears when highlighted on the
‘Saved’ list and NAV is pressed.
