🔍 Key Concepts

• Digital Selective Calling (DSC) routine (non‑distress) calls and their purpose • Difference between setting up contact (DSC) and voice communication content once contact is made • Which items are automatically included in a DSC call versus what the operator must select (e.g., working channel / category / called MMSI)

💭 Think About

• Think about the main goal of a routine DSC call to another vessel: what are you trying to establish before you start talking on voice? • Which of these options would be chosen on the radio to prepare for the follow‑up voice conversation, rather than details you would say over the microphone? • Consider which information a DSC controller already inserts automatically (like time, your identity/position) and which item you must manually choose to define how the conversation will continue.

✅ Before You Answer

• Identify which choice relates to how the two vessels will continue communications after the DSC alert. • Eliminate any options that are normally automatically included by the DSC equipment rather than operator‑selected for a routine call. • Ask yourself which piece of information is standard when shifting from DSC alerting to normal VHF radiotelephone working.
