What is Exhibition Mode and how do I activate or cancel it?

Exhibition Mode is designed for use by retailers when 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 and freezer do not get cold. To start Exhibition Mode, touch and hold the Freezer, Fridge, and Door Alarm buttons at the same time for 5 seconds during normal operation until the refrigerator chime sounds. To cancel Exhibition Mode, repeat the same action — touch and hold those three buttons simultaneously for 5 seconds until the chime sounds again. (Page 21)
