911 Dispatcher Practice Test

What should a dispatcher communicate when the service is not available for a call?

1. 10-6

2. 10-7

3. 10-5

4. 10-1

The correct answer is: 10-7

When a dispatcher communicates that the service is not available for a call, they use the code 10-7. This code is specifically defined within the ten-code system commonly used in law enforcement and dispatch operations to indicate that a unit is out of service or unavailable. The use of this code facilitates quick and effective communication in a high-pressure environment, allowing personnel to understand each other's status without unnecessary elaboration. The other codes in this choice set have different meanings; for instance, 10-6 typically means that a unit is busy but available for additional calls, while 10-5 is often used to request information or relay messages. The code 10-1 generally signifies that the signal is weak or unclear. Each code serves a distinct purpose, making it crucial for dispatchers to use the correct terminology for clarity and efficiency in emergency situations.
