What is the signaling protocol for a DSC distress alert?

The signaling protocol for a DSC distress alert is to use the dedicated distress button on the radio. This button is an integral feature of Digital Selective Calling (DSC) radios, designed specifically for emergency communications. When the distress button is pressed, the radio automatically sends out a distress message that includes vital information such as the identity of the vessel and its position. This message alerts all stations within range and other vessels of the distress situation and prompts an automated response from the coast guard or rescuers.

The significance of using the dedicated distress button lies in the fact that it streamlines the process of sending a distress signal, ensuring that standardized alerts are broadcasted quickly and accurately. This is essential during emergencies when time is critical, and it enhances the overall safety of maritime operations by enabling immediate alerts without requiring manual entry of information or voice transmissions, which could lead to confusion or delay.
