When to Replace Batteries
When the batteries are low, a low-battery message is displayed when you turn on the
graphing calculator.
To replace the batteries without losing any information in memory, follow the steps in
Appendix C.
Generally, the graphing calculator will continue to operate for one or two weeks after the
low-battery message is first displayed. After this period, the TI-84 Plus will turn off
automatically and the unit will not operate. Batteries must be replaced. All memory
should be retained.
Note: The operating period following the first low-battery message could be longer than
two weeks if you use the graphing calculator infrequently.
