The 10 Code for repeat message is

1. 10-9

2. 10-4

3. 10-5

4. 10-7

The correct answer is: 10-9

The 10 Code for repeating a message is indeed represented by 10-9. This code is commonly used in communication protocols, especially in law enforcement and emergency services, to streamline and clarify exchanges. When someone utters 10-9, it indicates that the listener did not understand a previous message and would like it to be repeated for clarity. This ensures that critical information is communicated accurately, which is essential in high-stakes environments. The other options refer to different meanings within the 10 Code system. For instance, 10-4 is typically used to indicate acknowledgment or that a message was received and understood. 10-5 is used for relaying the messages to another station, and 10-7 means “out of service,” indicating that a unit or person is unavailable for communication. Each code serves a specific purpose, but when it comes to requesting a repeat, 10-9 is the correct choice.
