u Reset
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 12-4).
k Low 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 communication operations after the low battery message
appears.
