First off lets start with a reminder of what the buttons on the back of your device do:
Adjusting the night light brightness is as easy as using the up (4) and down (5) buttons of the back of your device. This will increase or decrease the brightness of the screen making it easier to view during the day or at night.
Your Sleep Like Goldilocks device comes with the ability to automatically adjust the screen brightness based on the brightness in the room as well as the brightness of the night light.
Press button 2 to activate Auto-brightness - you can confirm that the auto brightness feature is activated by either pressing the up (4) or down (5) buttons which will be overridden by the auto-brightness feature, or by turning the night light on/off (3) and watching the screen brightness adjust.
