Live voice messages have precedence over other signals on that channel.

• A. Auto-initiated signals override live voice messages
• B. Signals operate independently with no precedence
• C. Live voice messages override all other signals on that channel
• D. There is no precedence between live voice and auto signals

Answer: (C)

Live voice messages have precedence on that channel, meaning human instructions take priority over automated or pre-recorded signals. This ensures urgent, real-time guidance from an operator is heard clearly even when other alerts are active. In practice, if a live operator is speaking, the system is designed to interrupt or override the ongoing auto signals so the live message comes through without being drowned out. This is crucial for safety because it allows responders to receive up-to-the-minute directions tailored to the current situation. The other ideas conflict with this approach: letting auto-initiated signals override live messages would blur critical instructions; signals operating independently with no precedence would create competing messages; and having no precedence at all would risk important live information being masked.
