What is Cooling Off mode and how do I turn it on or off?

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 compressor does not run and the refrigerator does not get cold. To start Cooling Off mode, touch and hold the Energy Saver button and the Freezer button simultaneously for 5 seconds; the chime will sound and the display will show 'OF OF.' To cancel, touch and hold the same two buttons again for 5 seconds. (Page 17)
