Simple soft reset (recovers keyboard control, restores most of RAM to the
state it was in at the last power-down, losing changes made in the current session:
press [On] + [Symbol] keys or using the Reset hole at the back of the unit.

Quick minor factory reset (clears most of memory, but maintains calculator name,
color theme, language):
press [Apps] + [Esc] keys and holding them while pressing the [On] key.
