What does the code 10-9 request the receiver to do?

1. Repeat

2. Stand by

3. Check your status

4. Proceed

The correct answer is: Repeat

The code 10-9 requests the receiver to repeat the last transmission. This communication code is commonly used in radio and other forms of communication to ensure clarity and accuracy. When information is critical, and there may be doubts about understanding or hearing it correctly, asking for repetition helps avoid misunderstandings and ensures that the message is conveyed accurately. In various contexts, such as emergency services, military communication, or other radio exchanges, the clarity of information is essential, making this code an important tool for effective communication. Other options, while relevant in communication contexts, address different types of responses. For example, a request to stand by indicates a need for the listener to wait for further instruction, whereas checking one’s status involves verifying operational readiness or condition, and proceeding typically directs the receiver to take action without needing a repeat of previous information.
