Which code indicates unit is in service and available for calls?

• A. In service; available for calls.
• B. Repeat the last transmission.
• C. Arrived at the scene.
• D. Emergency traffic; all units respond and air time is limited.

Answer: (A)

In police radio practice, a unit signals its availability with the status “in service; available for calls.” This means the unit is free to receive new assignments and is ready to respond. It’s the clear indication of readiness that dispatch relies on to assign calls. The other statements describe different actions: requesting a re-transmission, indicating arrival at a location, or signaling an emergency traffic priority. None of those convey general availability for new calls the way “in service; available for calls” does.
