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
