The Minitor VI is a Motorola voice pager widely used by fire departments and emergency medical services to alert responders to a call. Its formatted tones are designed to be heard clearly over station noise and to identify a specific group or officer. Clips of these alert tones have circulated online among scanner listeners, first responders and video creators, who reuse them to add realism to dispatch scenes. The duty officer version remains useful because it sounds official, immediate and instantly recognisable, even to viewers who have never carried a pager.
