All modes can be set from 10 to 120 minutes before sunset, then the light level gradually decreases and finally turns off at bedtime. 7 Natural Sounds + FM Radio: Enjoy 7 wonderful natural sounds (birdsong, ocean waves, streams, chirping, wind chimes, soft music, and piano music) and FM radio with adjustable volume (0-16 levels). You can also turn on the radio, which will automatically scan and store up to 40 stations for your favorite selections. You can also set it as your audio alarm. Two Alarms, Snooze Function, and 12/24 Hour Mode: Features a button for 12/24 hour mode and displays clock brightness (3 brightness levels: high, low (do not disturb), and off (time not displayed)). When the alarm sounds, the snooze function allows you to sleep for an additional 9 minutes, then it will turn off after 9 minutes (up to 5 times) for 15 minutes. 7 Sleep Modes & 20 Dimming Levels - No UV: Available in 7 colors when used as ambient light and also as a night light.
