🔍 Key Concepts

• VHF radio scanning functions on marine radios • Difference between channel scan and watch/dual-watch/tri-watch modes • The specific purpose of Channel 70 (DSC) vs Channel 16 (distress/safety/calling)

💭 Think About

• Think about what a standard "Scan" mode does when you enable it on a marine VHF: is it tied to specific channels, or to a list of channels you chose? • Which function name would more likely be used for watching just distress channels (like Ch-16 and Ch-70): would that usually be called "Scan" or something like "watch"/"DSC watch"? • Look at which answer describes a general capability versus a very specific programmed pattern—what is more typical of a generic "Scan" feature?

✅ Before You Answer

• Verify whether Channel 70 is used for voice communications or Digital Selective Calling (DSC) only. • Check your study materials for how a radio behaves in normal scan mode: does it step through many channels or only distress channels? • Confirm if monitoring Ch-16 plus one or two others on a timed basis is usually referred to as dual/tri-watch rather than generic scan.
