Using your Tonies Sleepy Bear Night Light is easy. First, place it on the Toniebox if you want to listen to the 75 - minute bedtime melodies and nature sounds. You can record your own goodnight messages for a personal touch. To adjust the brightness of the night light, there are 4 levels to choose from. The auto power - off function will turn it off after 30 minutes, so you don't have to worry about it staying on all night. At the lowest brightness level, it can run for up to 240 hours. It can be used as a night light even without the Toniebox. This product is suitable for children aged 3 and up. Keep it away from water and clean it with a soft, dry cloth. Don't expose it to extreme temperatures or rough handling.
