6 Overview of Calculator Operations
Resetting the Calculator
Because the calculator includes alternative methods that let you clear
data selectively, use reset carefully to avoid losing data needlessly. (See
“Clearing Calculator Entries and Memories” on page 6.)For example, you
might reset the calculator before using it for the first time, when starting
a new calculation, or when having difficulty operating the calculator and
other possible solutions do not work. (See “In Case of Difficulty” on
page 100.)
