In Manual Mode

From the home screen, if you tap the Soothing box, you can control the sound machine volume by adjusting the volume slider of your Sound card.

​In Smart Mode

In Smart Mode, the sound machine volume will automatically change based on the baby's sleep state. If you would like to override the Smart Mode volume, you can do this by tapping on the Soothing box from the home screen and adjusting the volume level on the slider. The new level will be in effect until the baby's sleep state changes.

You also have the option to lock the updating setting between 1 minute and 30 minutes. After the lock timer runs out, Smart mode will resume.
