đ Key Concepts
⢠ARQ telex procedural signals used in maritime NBDP/telex-at-sea
⢠The specific meaning of +?, NNNN, KKKK, GA+, DIRTLX, and BRK+
⢠The normal order of signals when you: 1) pass the line to the other operator (manual over), 2) finish your message text, 3) finally end the terminal connection
đ Think About
⢠First, match which ARQ code means "manual over/go ahead" in telex exchanges, then see which choice starts with that code.
⢠Next, identify which code is commonly used to mean "end of message text" in radiotelex procedures.
⢠Finally, determine which remaining code in that answer choice represents ending the connection to a land destination terminal, and check that the overall order is logical for a complete telex exchange.

Before You Answer
⢠Verify from your radiotelex notes which signal is used for manual intervention / manual over between operators.
⢠Check which of NNNN or KKKK is associated with end of message text versus end of transmission/connection in telex procedures.
⢠Ensure the chosen sequence follows a natural progression: operator handover â message text completed â connection to land terminal closed, not the other way around.
