This parameter sets the level of aggressiveness when setting a reduced quiet zone (the margin on either side of a barcode), and applies to symbologies enabled by a Reduced Quiet Zone parameter.
Because higher levels increase the decoding time and risk of mis-decodes, Zebra strongly recommends enabling only the symbologies which require higher quiet zone levels, and leaving Reduced Quiet Zone disabled for all other symbologies. Options are:
1D Quiet Zone Level 0 - The scanner performs normally in terms of quiet zone.
*1D Quiet Zone Level 1 - The scanner performs more aggressively in terms of quiet zone.
1D Quiet Zone Level 2 - The scanner only requires a quiet zone at the end of barcode for decoding.
1D Quiet Zone Level 3 - The scanner decodes anything in terms of quiet zone or end of barcode.
