What radio 10 code is used when you don’t understand what the dispatcher has said and you need them to repeat their transmission?

10-78
10-99
10-9
10-4

The correct answer is: 10-9

The code you would use when you don’t understand what the dispatcher has said and need them to repeat their transmission is 10-9. This code is specifically designated for requesting a repeat of the last message, making it an essential part of communication in various radio systems. Using this code ensures that the dispatcher knows you need clarification, allowing for effective and clear communication to avoid misunderstandings. The other codes serve different purposes; for instance, 10-78 pertains to needing assistance or backup, 10-99 is used to indicate a situation where there is a problem with a unit, and 10-4 indicates acknowledgment of understanding a message. Thus, 10-9 stands out as the appropriate choice for the situation described.
