What communication code would indicate a condition issue requiring a repeat?

The correct communication code indicating a condition issue that requires a repeat is 10-9. This code is specifically used in law enforcement communication to ask for a message or information to be repeated. It is crucial in situations where clarity is needed, particularly in noisy environments or under stressful circumstances, ensuring that officers receive accurate and complete information.

The other codes serve different purposes: 10-3 typically relates to a stop transmitting or to cease communication, 10-4 usually indicates acknowledgment or that the message was received, and 10-5 involves relaying a message. Thus, the function of 10-9 as a request for repetition distinctly underscores its importance in facilitating clear communication among law enforcement personnel.
