Florida Security Guard Class D Practice Exam

The correct answer is "10-8", as this is the standard 10-code for "back in service" in the context of security communication. In security and police work, 10-codes are used as a form of shorthand to communicate various states, conditions or instructions over radio communications that are brief and swiftly understood. While the use and meanings of 10-codes can vary between different agencies or regions, "10-8" is widely recognized to mean "back in service". This is typically used when an officer or guard is back in service after being temporarily unavailable, such as after responding to an incident or returning from a break. This lets dispatch and other personnel know that the officer or guard is now free to respond to new tasks or incidents.
