In APCO 10-codes, 10-84 refers to "If meeting, advise ETA."
This code is commonly used in communication among law enforcement or emergency services to indicate that if personnel are meeting with someone (another officer, dispatcher, or public), they should provide their estimated time of arrival (ETA).
For example, a communication might look like this:
- Unit 3: "Dispatch, I'm on my way to meet Unit 7. I'm currently 10 minutes out."
- Dispatcher: "Copy that, Unit 3. Please advise ETA when you arrive."
Using 10-84 helps ensure that all units are aware of each other's expected arrival times, facilitating better coordination and communication within the team.
