🔍 Key Concepts

• Digital Selective Calling (DSC) and how an "address book" is used in GMDSS radios • Difference between MMSI (Maritime Mobile Service Identity) and other identification numbers like IMO or call sign • What specific data you need to store to easily call another ship or coast station from the radio

💭 Think About

• Ask yourself: When you pick a name from the radio’s address book to call them, what unique number does the radio actually use to set up the DSC call? • Which of the listed identifiers is used for safety and routine DSC calls between ships and shore stations, rather than for registration or paperwork? • If you were programming your GMDSS/DSC radio, which combination of details would be most practical to save frequently‑called stations?

✅ Before You Answer

• Identify which item in the choices is the unique numeric identity used by DSC radios to call another station • Confirm whether an address book in this context is for radio contact purposes, not for administrative/registry identification • Check which choice pairs that unique radio identity with a human‑readable label that helps the operator recognize who they’re calling
