Pressing the P button resets the calculator to its initial defaults.
Warning!
Never perform this operation unless you want to totally clear the memory of the calculator. If
you need the data currently stored in memory, be sure to write it down somewhere before
performing the P button operation.
• Pressing the P button while a calculation operation is being performed (while the
calculator is performing a calculation internally) deletes all data in memory.
• You can also reset the calculator using front panel key operations (see 11-4 Reset). Use
the P button to reset only while the front panel keys are disabled for some reason.
