The device functions as a projector or night lamp, depending on the setting. It has three modes of use, depending on the child's age:

• Bedside lamp (Age: 0-12m): Equipped with a SMART SENSOR sound sensor that responds to the baby's crying. When the baby cries, a soft blue LED light turns on to help your little one fall back asleep. The light automatically turns off after 10 minutes.
• Crib projector (Age: 6-18m): Activated by pressing the ON button. Displays colorful stars and plays 6 different melodies and 3 natural sounds. It has adjustable sound volume and turns off automatically.
• Night table lamp (Age: 12m+): Also activated with the ON button. Easily placed on the bedside table next to the bed. Displays colorful stars and plays 6 different melodies and 3 natural sounds. It can be set to loud, silent, or off volume and turns off automatically.

Required batteries: 3 x AA (1.5V); batteries not included. The night lamp attaches to the bed using two straps.
