1D Quiet Zone Level (Parameter #1288, SSI #F8h 05h 08h)
This feature sets the level of aggressiveness when decoding bar codes with a reduced quiet zone (the margin on either side of a bar code), and applies to symbologies enabled by a Reduced Quiet Zone parameter. Because higher levels increase the decoding time and risk of mis‑decodes, it is strongly recommended to enable only the symbologies that require higher quiet zone levels, and leaving Reduced Quiet Zone disabled for all other symbologies.
- 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 bar code for decoding.
- 1D Quiet Zone Level 3—the scanner decodes anything in terms of quiet zone or end of bar code.
Scan one of the following bar codes to set the 1D quiet zone level. By default, this parameter is set to Level 1.
