Product Reference Guide

                           319

The reader’s beeper sounds and its LED illuminates to indicate various func-

tions 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 programma-

ble, 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.
