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 — in this mode, the fan motor and lights work normally but the compressors do not run and the refrigerator does not get cold. To activate it, press and hold the Energy Saver button and the Power Freeze button simultaneously for 3 seconds; the chime will sound and the display will flash 'OF OF.' To cancel it, press and hold the same two buttons again for 3 seconds. (Page 3)
