In APCO (Association of Public-Safety Communications Officials) 10-codes, 10-1 typically means "Signal Weak" or "Receiving Poorly". It is used by law enforcement officers or dispatchers to indicate that the radio transmission being received is weak or unclear, making communication difficult.
Here’s how it might be used in a real-world scenario:
- Officer: "Dispatch, this is unit 45."
- Dispatch: "Unit 45, you're 10-1. Please repeat."
In this exchange, dispatch is telling the officer that the radio signal is weak or the message was unclear (10-1), so they should repeat or try again.
The code is particularly useful when dealing with radio communication issues due to distance, interference, or technical problems. Like other 10-codes, 10-1 provides a quick and standardized way for officers and dispatchers to communicate essential information about the quality of their radio transmissions.
