Radio codes are standardized signals used in communication, particularly among emergency services like police, firefighters, and paramedics. These codes help convey information quickly and efficiently, often using numbers or short phrases to represent complex messages. For example, the 10-codes system includes codes like "10-4" for acknowledgment and "10-20" for location. These codes enhance clarity and reduce misunderstandings during high-pressure situations. In addition to 10-codes, some agencies use phonetic alphabets like the NATO phonetic alphabet to spell out names or locations clearly over radio transmissions. This ensures that critical information is communicated effectively.
