Sangean CL-100 Portable Clock Radio - Stereo

NOAA Alert Function: Your Weather Hazard Alert Radio will automatically sound an alert tone siren and flash the corresponding LED color indicator when it receives a weather or civil emergency broadcast from NOAA (Weather Band).
Specific Area Message Encoding (S.A.M.E.): Allows you to store up to 25 different location codes into memory. Each code identifies a specific geographic area, typically a county as defined by NOAA. Setting the S.A.M.E. location helps reduce unnecessary alerts.
External Device Compatible and Radio Broadcast Data System (RBDS): The CL-100 has a built-in external alert output jack for other accessories (e.g. hearing / visually impaired , flashing light, indoor / outdoor siren / alarm). You can also set the date, weekday and time on a digital watch manually or automatically by RBDS CT set.
