In the previous days or hours, the temperature in the freezer zone has risen too high because of a power cut or interruption to the power supply.
Press the alarm button for as long as nA is illuminated.
The warmest temperature recorded in the freezer zone will appear for about 1 minute on the temperature display. Then the temperature display will change to the current temperature in the freezer zone.
Depending on the temperature displayed, you should check whether food in the freezer has started to thaw or has defrosted. If it has, it should be used as soon as possible. Defrosted food may only be re-frozen after it has been cooked.
