🔍 Key Concepts

• DSC (Digital Selective Calling) Distress alerts responsibilities of all stations that receive them • The effect of acknowledging a DSC Distress on how other ships and shore stations react • When you should not transmit or relay a Distress alert from your GMDSS equipment

💭 Think About

• If your ship receives a DSC Distress alert, what happens system-wide when someone sends a DSC acknowledgement back? How could that affect rescue efforts? • Which of the options would most directly prevent you from interfering with the original distress communication or with coast station procedures? • Think about which actions are routine or optional (like saving or clearing messages) versus which could change how other stations respond.

✅ Before You Answer

• Verify what acknowledging a DSC Distress alert does to other ships’ radios on that channel. • Check GMDSS procedures on who should normally acknowledge a Distress alert first (ship vs. coast station). • Eliminate any option that suggests you should take no special care with Distress alerts or that describes only routine housekeeping steps.
