How do I activate Power Freeze and how long does it run?

Press and hold the Freezer button for 3 seconds to activate the Power Freeze function, which speeds up the freezer compressor to cool the freezer rapidly. Power Freeze is useful for quick-freezing items or making a large quantity of ice, and it is recommended to activate it at least 20 hours before freezing large amounts of food. The function turns off automatically after 50 hours to decrease energy consumption, or you can cancel it manually by pressing and holding the Freezer button again for 3 seconds. (Page 24)
