AEMCA Practice Exam

Which of the following codes is associated with returning to a base location?

1. 10-19

2. 10-3

3. 10-4

4. 10-7

The correct answer is: 10-19

The code associated with returning to a base location is 10-19. In communication systems, particularly among emergency services and law enforcement, specific codes are established to facilitate concise and efficient communication. The 10-19 code specifically indicates “return to base.” This means that personnel are instructed to head back to their original station or a designated location after completing a task or responding to a call. The other codes mentioned serve different purposes: 10-3 typically means "stop transmitting," which is a directive for communication clarity; 10-4 is understood as "message received" or acknowledgment of a message; and 10-7 indicates “out of service,” meaning the unit is not available for duty. Understanding these distinctions is crucial for effective communication in operational settings.
