LED and Beeper Indications

The scanner’s beeper sounds and its LED illuminates to indicate various functions or errors on the reader. A “Green Spot” also lights to indicate a good read. 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 barcode labels. Refer to the PG for a more detailed list.
