4.4 Emergency calls (DSC safety/ urgency/ distress calls)
In emergency, the DSC is available for safety/urgency/distress calls. For safety and urgency calls,
either individual or all ships is selectable for the type of call. Also, there is a way to send distress
alerts after selecting, or not selecting, the type of distress on the menu. In both cases, the
dedicated DISTRESS button is used to send the distress alerts.
