The calculator responds to certain conditions or keystrokes by displaying a
message. The
â
symbol comes on to call your attention to the message. For
significant conditions, the message remains until you clear it. Pressing
Å
or
~
clears the message; pressing any other key clears the message and executes that
key's function.
