In APCO 10-codes, 10-97 refers to "Signal Check."
This code is commonly used in law enforcement and emergency services to request or confirm the status of a communication signal or radio connection. When a unit uses 10-97, they are typically checking to ensure that their radio equipment is functioning properly or confirming that they are receiving a clear signal.
For example, a radio communication might look like this:
- Unit 5: "Dispatch, this is Unit 5. Can you confirm a 10-97 on my signal?"
- Dispatcher: "Unit 5, your signal is strong. You are 10-97."
Using 10-97 helps maintain effective communication within the department and ensures that all units can communicate clearly and reliably during operations.
