How do I adjust the temperature if the refrigerator or freezer is too warm or too cold?

Adjust the refrigerator control first, then wait 24 hours before checking the freezer temperature and making further adjustments. If the refrigerator section is too warm, turn the refrigerator control to the next highest level; if too cold, set it to the next lower level. Always wait at least 24 hours between adjustments, and also check that air vents are not blocked by food packages. (Page 12)
