You can change the light on top of the monitor arc by doing one of the following:
From the Cradlewise app home screen, select the 3 horizontal dots on the monitor and select Crib Light, or go to Settings > Crib > Crib Light.
Turn on Smart Mode to have the light automatically adjust to the room's ambient light, making it brighter when the room is brighter and dimmer as the space gets darker.
Turn off Smart Mode to manually adjust the light's brightness.
Slide all the way to the left to turn off the light completely.
