The natural way to fall asleep. This unique alarm clock features a choice of four relaxing nature sounds — ocean surf, a rushing brook, forest birds and wind chimes. With 18 preset radio stations and a CD player. An auxiliary audio input accommodates an MP3 player or iPod®. And a gentle wake alarm that will wake you gradually with increasing volume. The battery backup ensures your alarm will sound even if the power goes out. Plus, an auto-set time and date, so all you have to do is plug it in and it sets itself.
