🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) responsibilities of the radio operator • The role of FCC Rules, Part 80 in maritime radio services • Where distress, urgency, and safety procedures are formally laid out for U.S.-licensed stations

💭 Think About

• Which document is legally binding on how you must operate your GMDSS equipment in a distress, rather than just offering general guidance or technical instructions? • Which FCC Part specifically covers the maritime services and GMDSS, and which Parts cover other types of radio services? • Among the choices, which one is most focused on operational procedures for distress, urgency, and safety rather than equipment operation or recommendations?

✅ Before You Answer

• Identify which FCC Part applies to maritime radio services and GMDSS (compare Part 80 vs Part 90). • Distinguish between equipment manuals (how to push the buttons) and regulatory procedures (what calls and messages you must send, in what order). • Decide which option explicitly addresses distress, urgency, and safety communications procedures under GMDSS.
