In APCO 10-codes, 10-41 refers to "Begin tour of duty."
This code is typically used by law enforcement officers or emergency responders to indicate that they are starting their shift or beginning their active duty for the day. It serves as a way to formally announce their availability for service and readiness to respond to calls.
For example:
- Officer: "Dispatch, this is Officer Smith, 10-41 at 0800 hours."
- Dispatcher: "Copy that, Officer Smith. You're now on duty."
Using 10-41 helps ensure that all parties involved in communication are aware of who is currently on duty and available to respond to incidents or calls for service.
