LED AND BEEPER INDICATORS

The scanner’s beeper sounds and its green LED illuminates to indicate
various functions or errors on the scanner. The tables that follow list
these indications. An exception is that the scanner’s functions are
programmable, and may or may not be turned on. For example, some
indications (such as the power-up beep) can be disabled using
programming bar code labels.
