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 tables below list these
indications. One exception to the behaviors listed in the tables is that the reader’s functions are
programmable, and 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.
