Which type of radio tone is used to announce a priority message?

The steady alert tone is used to announce a priority message within emergency communication systems. This tone is specifically designed to capture the immediate attention of responders and signify the urgency of the information being transmitted. It is typically employed to prioritize critical communications, ensuring that emergency personnel are alerted promptly to important announcements or urgent updates.

In contrast, other tones serve different purposes. The warbler tone is generally used for less urgent messages or alerts, which may not demand immediate action. The emergency tone, while also indicative of urgent situations, is often used to initiate an emergency broadcast rather than to specifically signal a priority message directed to responders. The broadcast tone is utilized for non-urgent broadcasting of information and does not convey the same level of urgency or priority that the steady alert tone embodies.
