All Hazards Noaa Weather Radio Public Alert Sangean's new compact Table-Top S. A.m. E. Weather Alert Radio is loaded with all the key features. The Cl-100 is a Public Alert Certified weather radio and receives all Noaa reports informing people about severe weather advisories, monitors and warning conditions, civil emergencies, hazards, and evacuation details, so you can have more time to react before dangerous storms hit your area. When you're in a tornado path, seconds can mean the difference between life and death and that's when the Sangean Cl-100 comes into play. A 3.5mm stereo Auxiliary Input socket is provided on the rear of the Cl-100 to allow connection of an external audio device such as an MP3 or Cd player. The Cl-100 also has a built-in external alert output jack for other accessories (e. g. hearing/visually impaired, flashing light, in/outdoor siren/alarm).
