The code 10-7 is widely recognized in law enforcement and emergency services to indicate "Out of service." When a unit is marked as out of service, it communicates that they are not available to respond to calls or emergencies at that time. This could be due to a variety of reasons, such as being on a break, handling a non-emergency situation, or performing administrative duties.

Understanding this code is crucial for dispatchers as it helps in managing resources and ensuring that calls for service are directed to available personnel. When responding agencies understand the status of their units, it enhances the effectiveness of response operations and maintains clear communication channels among responders.

The other options refer to different statuses: “In service” indicates a unit is active and ready to respond, “Repeat” suggests the dispatcher is requesting the information to be reiterated for clarity, and “Busy unless urgent” implies that while a unit is occupied, they will respond to urgent matters, but none of these pertain to a unit being out of service like the 10-7 code does.
