Getting Started

vWatch for this symbol in the margin. It identifies examples or keystrokes that are shown in RPN mode and must be

performed differently in ALG mode. Appendix C explains how to use your calculator in ALG mode.

Important Preliminaries

Turning the Calculator On and Off

To turn the calculator on, press . ON is printed on the bottom of the key.

To turn the calculator off, press . That is, press and release the shift key, then press (which has OFF printed in yellow above it). Since the calculator has Continuous Memory, turning it off does not affect any information you've stored.

To conserve energy, the calculator turns itself off after 10 minutes of inactivity. If you see the low–power indicator ( ) in the display, replace the batteries as soon as possible. See appendix A for instructions.

Adjusting Display Contrast

Display contrast depends on lighting, viewing angle, and the contrast setting. To increase or decrease the contrast, hold down the  key and press  or .
