🔍 Key Concepts

• VHF DSC radio functions and what "Scan" generally does on most marine radios • Difference between scanning channels vs. monitoring one channel for distress • Purpose of Channel 70 (DSC) and Channel 16 (distress/safety/calling)

💭 Think About

• Ask yourself: When you press the "Scan" button on a marine VHF, what do you actually see the radio doing with the channels? • Consider whether "Scan" is normally tied to specific channels (like 16, 70, or 13), or if it is a more general feature that can include multiple user‑selected channels. • Think about how a radio would be designed to keep watch for DSC distress alerts—would that rely on the regular "Scan" function or on a dedicated watch receiver?

✅ Before You Answer

• Verify what Channel 16 is primarily used for (distress, safety, and calling) and how it is normally monitored. • Verify what Channel 70 (DSC) is used for and whether radios use the standard voice "Scan" function to watch it. • Check how the term "scan" is defined in your study materials: does it mean watching one specific channel, or cycling through multiple channels in sequence?
