LED and Beeper Indications
The reader’s beeper sounds and its LED illuminates to indi-
cate 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 program-
mable, and so may or may not be turned on. For example, cer-
tain indications such as the power-up beep can be disabled
using programming bar code labels.
