kRestart and Reset

uRestart

Should the calculator start to act abnormally, you can restart it by pressing the RESTART button (P button). Note, however, that you should only use the RESTART button only as a last resort. Normally, pressing the RESTART button reboots the calculator’s operating system, so programs, graph functions and other data in calculator memory is retained.

Important!

The calculator backs up user data (main memory) when you turn power off and loads the backed up data when you turn power back on.

When you press the RESTART button, the calculator restarts and loads backed up data.

This means that if you press the RESTART button after you edit a program, graph function, or other data, any data that has not been backed up will be lost.

uReset

Use reset when you want to delete all data currently in calculator memory and return all mode settings to their initial defaults.

Before performing the reset operation, first make a written copy of all important data. For details, see “Reset” (page 12-3).

kLow Battery Message

If the following message appears on the display, immediately turn off the calculator and replace batteries as instructed.

If you continue using the calculator without replacing batteries, power will automatically turn off to protect memory contents. Once this happens, you will not be able to turn power back on, and there is the danger that memory contents will be corrupted or lost entirely.

You will not be able to perform data communications operations after the low battery message appears.
