LED and Beeper Indications
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
following tables list these indications. One exception to
the behaviors listed in the tables is that the reader's func-
tions 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.
