Background
The Emergency Alert System is the USA's national warning system. Designed originally under the Emergency Broadcast System to allow the President to speak on all TV and radio systems, the EAS was an upgrade allowing for better localized alerts. SAME tones were introduced to help transmit data to encoders, to identify locations of any event. This system was implemented in 1997.
EASyPLUS Screen (2004-2016?)
Visuals: On a black background, there is white VCR OSD Mono text. This text is in 3 lines, the top reading "EMERGENCY ALERT SYSTEM", the middle line displaying the alert sender, the next to bottom line reading "issued a", the bottom line displaying the alert. Between the first and second line, a scroll line reads "[ALERT SENDER] has issued a(n) [ALERT] for the following counties/areas: [LOCATIONS]. Effective until [TIME] Variants:
Technique: Trilithic EASyPLUS Character Generator/EAS Encoder.
Audio: The SAME tones, followed by the EBS alert tone, then the audio message, then the EOM tones
Audio Variants: On some weather alerts, the 1050Hz tone from NOAA Weather Radio system plays, often because the EASyPLUS monitors weather radio channels to relay alerts.
