The CKW2000 dual alarm clock radio by Emerson keeps you in the know with its NOAA weather alert system. It utilizes Specific Area Message Encoding (S.A.M.E.) technology which eliminates annoying alarms that don't apply to your specific area. In addition to audible alerts, the LED indicators inform if the alert is a "warning", "watch", and "statement". The CKW2000 includes Emerson standard clock radio features including: Sure-Alarm battery backup system, gradual buzzer alarm, wake to radio alarm, and programmable 90-minute sleep timer. The 20-station preset memory allows you to program up to 20 of your favorite radio stations - 10 AM and 10 FM. The 2.5-inch dynamic speaker delivers smooth sound that makes it great for everyday use or to ease you awake in the morning.
