When signaling by flashing light, what...

🔍 Key Concepts

• Morse signaling by flashing light uses internationally standardized meanings for single letters • Some letters are used as procedural signals (for managing the communication itself), not for message content • Think about what "C" might stand for in plain English in the context of confirming or denying information

💭 Think About

• Ask yourself: In message procedures, which signal would logically be used to clearly confirm that a previous message is correct and understood? • Look at the options and decide: which one describes a positive, confirming function rather than a question or change? • Which option sounds like something you would send at the start or end of a communication to show agreement or correctness?

✅ Before You Answer

• Eliminate options that indicate uncertainty (like questions or changes of mind) if you think "C" is used for confirmation • Decide whether "C" is more likely to mean a request for information or a statement about the status of information already received • Verify in your study materials which single-letter Morse/flash signal is used as the procedural signal for confirmation
