"This is a test of the Emergency Broadcast System. The broadcasters of your area in voluntary cooperation with the FCC and other authorities have developed this system to keep you informed in the event of an emergency. If this had been an actual emergency, you would have been instructed to tune to one of the broadcast stations in your area."
