When to Replace Batteries
When the batteries are low, a low-battery message is displayed when
you:
•
Turn on the calculator.
•
Download a new application.
•
Attempt to upgrade to new software.
To replace the batteries without losing any information in memory, follow
the steps in Appendix B.
Generally, the calculator will continue to operate for one or two weeks
after the low-battery message is first displayed. After this period, the
TI-83 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 calculator infrequently.
