LED and Beeper Indications
The reader’s beeper sounds and its LED illuminates to indi-
cate 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 tables 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 programming bar code labels.
