Alertas Especial Difusión.

It's the new TV/Radio warning system for Puerto Chango, used alongside Puerto Chango's regular national alerting systems. It uses Emergency Alert System technology also used in the US, and uses the same tones. In it's first year (2009) it used the EAS black screen with English test, but later currently uses modified EAS screens.
