BASIC DEFINITIONS The Keys To keep your calculators as compact as possible, some keys have more than one function. You can change the function of a key by pressing another key first, or by setting the calculator in a certain mode. The following pages give you more detailed explanation of each key’s use and function. [ 2ndF ] Second Function Select Key Some keys have a second function inscribed above them. To perform this second function, press [ 2ndF ]. “ 2F ” appears in the display
