How do I activate and cancel Power Freeze on the freezer?

To activate Power Freeze, touch and hold the Freezer button for 3 seconds, which will speed up the freezer compressor to cool the freezer rapidly. To cancel Power Freeze manually, press the Freezer button and re-set the Freezer temperature. Power Freeze will also turn off automatically after 50 hours to decrease energy consumption, and note that using this function will increase the refrigerator's energy consumption. (Page 24)
