Texas Instruments Titanium TI-89 User Manual

Getting Started 8
Note: ® is the second function of the ´ key.
The calculator’s Automatic Power Down™ (APD™) feature prolongs battery life by
turning the calculator off automatically following several minutes of inactivity. When you
turn on the calculator after APD:
• The display, cursor, and any error conditions are exactly the same as before APD.
• All settings and memory contents are retained.
Note: APD does not occur if a calculation or program is in progress, unless the program
is paused. If a program is running but waiting for a key press, APD will occur after
several minutes of inactivity.
