Poor Quality PDF Codes
This setting improves the scanner’s ability to read damaged or badly printed PDF 
codes by combining information from multiple images. It is useful when a 
complete barcode cannot be seen in one image. This setting does not affect 1D 
barcode reading. Default = Poor Quality PDF Reading Off.
Reread Delay
This sets the time period before the scanner can read the same barcode a second 
time. Setting a reread delay protects against accidental rereads of the same 
barcode. Longer delays are effective in minimizing accidental rereads. Use shorter 
delays in applications where repetitive barcode scanning is required. Reread Delay 
only works when in Presentation Mode. Default = Medium.
