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 follow-
ing  tables  list  these  indications.  One  exception  to  the
behaviors listed in the tables is that the reader’s functions
are programmable, and so 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.
