What is Demo Mode and how do I turn it off?

Demo Mode disables all cooling in the refrigerator and freezer sections to conserve energy while the unit is on display in a retail store. When activated, OFF will display on the control panel. To deactivate Demo Mode, open either refrigerator door and press and hold the Refrigerator Temp and Ultra Ice buttons at the same time for five seconds. The control panel will beep and the temperature settings will display to confirm Demo Mode is deactivated. (Page 19)
