If a button has not been pressed for 10 minutes, the display screen will drop to 50% brightness level. If no button is pressed within one minute after that, the unit will power off to
extend battery life. Pressing any button quickly any time before the unit turns off will return the screen to full brightness level and reset the auto off countdown process, without
changing any other settings.
Note: Once you enter the setup interface, you cannot use Power Button (A) to turn the device off. Please press and hold the image brightness button
for 3 seconds to return
to the review interface first. Then press and hold power button 3 seconds to turn the unit off.
