Annunciator Meaning Chapter
The " (Busy)" annunciator appears while
an operation, equation, or program is
executing.
When in Fraction–display mode (press
), only one of the "" or "" halves
of the ""' annunciator will be turned on
to indicate whether the displayed numerator
is slightly less than or slightly greater than its
true value. If neither part of "" is on, the
exact value of the fraction is being
displayed.
