Indicators
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 functions are pro-
grammable, and so may or may not be turned on. For example, certain indi-
cations such as the power-up beep can be disabled using programming bar
code labels.
