🔍 Key Concepts

• Research vs. operational use: Some publications are meant to help you operate during a distress, others are better for planning and installing equipment beforehand. • Manufacturer’s equipment manuals: Think about when you need very specific information on how to wire, program, or update a particular model of radio, EPIRB, or other GMDSS equipment. • Scope of each publication: Consider whether a document mainly lists shore stations/services or whether it explains how to set up and configure your onboard equipment.

💭 Think About

• Ask yourself which option includes a source that explains your specific equipment’s functions, settings, and installation details, not just where to call for help. • Identify which publications are primarily used for operational distress/urgency/safety communications (who to call and on what frequencies) versus those aimed at system design and setup. • For each answer choice, decide: would I use these books when wiring, programming, or updating radios and distress equipment, or mostly when actually sending distress messages?

✅ Before You Answer

• Make sure at least one resource directly covers your specific equipment model and its configuration details. • Confirm which publications (e.g., ALRS, ITU Lists, FCC Part 80) are mainly directory/regulatory references rather than setup/planning guides. • Check that the combination of resources in your chosen answer supports both technical setup and understanding where/how the equipment will be used in the GMDSS system.
