Indicators
The reader's beeper sounds and its LED illuminates to indicate various functions or
errors on the reader. An optional "Green Spot" also performs useful functions. The fol-
lowing tables list these indications. One exception to the behaviors listed in the table is
that the reader's functions are programmable, and so may or may not be turned on. For
example, certain indications such as the power-up beep can be disabled using program-
ming bar code labels.
