911 Dispatcher Practice Test

Which of the following is the appropriate response to acknowledge that a message has been understood?

1. 10-3

2. 10-4

3. 10-8

4. 10-2

The correct answer is: 10-4

The appropriate response to acknowledge that a message has been understood is "10-4." In the context of radio communications, particularly in emergency services and 911 dispatching, "10-4" is part of the ten-codes system used to communicate succinctly and clearly. Specifically, "10-4" means "Acknowledged" or "Message received and understood." This transmission ensures that the sender knows their message was not only received but also comprehended, which is critical in emergency situations where clarity is essential for effective operations. In contrast, the other terms serve different purposes within the ten-codes system. For example, "10-3" indicates a request to stop transmitting, "10-8" means that an officer is in service or available, and "10-2" typically relates to signal strength or clarity of communication. Understanding these codes helps maintain clear communication within the dispatching environment, ensuring that information is relayed accurately and efficiently.
