LED and Beeper Indications
The scanner’s beeper sounds and its two-color LED illuminates to indicate various functions or 
errors on the scanner. The tables below list these indications. One exception to the behaviors 
listed in the tables is that the scanner’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 labels.
