All participating police departments have been provided with dedicated fax line numbers for WBAP and KRLD radio stations. When a police department decides to activate the Amber Plan, they send the two stations a written description of the child, the suspect, the suspect vehicle, the time and place of the incident, and any other relevant information. The two stations quickly verify the activation. Then, using the Emergency Activation System (EAS), an audio bulletin containing the police information is sent simultaneously to all participating radio and TV stations in Dallas/Fort Worth.
The bulletin is originated by WBAP and KSCS radio stations because of their designation as the primary EAS outlets for the Dallas/Fort Worth listening area. Once the bulletin is received, all Amber Plan radio and TV stations break from regular programming and repeatedly broadcast the information to listeners and viewers.
