911 Dispatcher Practice Test

What is indicated by the code 10-9 in dispatcher communication?

1. Repeat

2. Relay

3. Stop transmitting

4. Out of service

The correct answer is: Repeat

In dispatcher communication, the code 10-9 signifies "Repeat." This is an important protocol used in radio communication to ensure clarity and avoid misunderstandings. When a dispatcher or responder hears something that is unclear or not fully understood, utilizing the 10-9 code prompts the sender to repeat their last transmission. This helps maintain effective communication, especially in high-pressure situations where accurate information is critical. Maintaining clear and correct communication is vital for the safety of both responders and the public, and the use of designated codes like 10-9 plays a significant role in achieving this. Other options provided may refer to different actions, but 10-9 specifically calls for repetition, which is essential in the dispatch field.
