HF680 Series User Guide 39
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.
