Resetting The Calculator - HP 17bll+ User Manual

Resetting the Calculator

If the calculator doesn't respond to keystrokes or is behaving unusually,
attempt to reset it. Resetting the calculator halts the current calculation,
clears the calculator line, and displays the MAIN menu. Stored data
remains intact.
To reset the calculator, hold down
key from the left. Repeat if necessary. The calculator displays
            to confirm that reset has occurred.
The calculator can reset itself if it is dropped or if power is interrupted.
If the calculator still does not respond to keystrokes, use a thin, pointed
object to press the reset hole near of the battery compartment.
Never press the reset button twice within 1 second as
this could result in a memory lost.
Warning
Resetting the calculator halts the current calculation, clears the calculator
line, and displays the MAIN menu. Stored data remains intact except
setting those conditions: double-space printing off, printer tracing off,
printer without the ac adapter, and beeper on.
