LED and Beeper Indications

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 indi-
cations. 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 bar code la-
bels. Reference the PRG for a more detailed list.
