What is Cooling Off mode and how do I activate or cancel it?

Cooling Off mode (also called Shop mode) is designed for retailers displaying refrigerators on the shop floor — the fan motor and lights work normally, but the compressors do not run, so the refrigerator and freezer do not get cold. To start Cooling Off mode, touch and hold the Energy Saver button and the Power Freeze button simultaneously for 5 seconds; the temperature display will flash 'OF OF.' To cancel, press and hold those same two buttons again for 5 seconds. (Page 12)
