What is indicated by the 10-1 code?

The 10-1 code indicates that the message being received is poor. This code is part of a standard phonetic alphabet used by many organizations, including transit authorities, to facilitate clear communication regarding the quality of radio signal transmissions.

When a communication is marked with 10-1, it alerts the other party that their transmission is difficult to hear or understand, prompting them to either repeat the message or adjust their transmission method. It plays a critical role in ensuring that information is conveyed accurately and effectively, especially in situations where clear communication is crucial for safety and operational efficiency.

Understanding these codes is vital for personnel to navigate incidents or coordinate effectively, leveraging clear and concise communication to ensure the safety and effectiveness of the transit system.
