Is the Memory Lane CareScreen connected to the mains?
If not, connect the CareScreen to the mains. The CareScreen starts up automatically after a few seconds.
If the screen remains black, but the red light is on, you should wait until the battery is at least 3% charged. The CareScreen will start up automatically after a while.
