LED and Beeper Indications
The reader’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 indica-
tions. 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. Reference
the PRG for a more detailed list.
