Why does the screen turn dark and what should I do to light up the screen?

A power saving mode is built in the app. When the ATMS is not in use, the app will be on a standby mode in order to extend the device’s battery life. When users step up to the ATMS, the display screen will light up again. You can switch off the power saving mode in Settings->About and the display screen will remain bright.
