Decode Performance
If this parameter is set to on, one of three decode levels assigned to the "Decode
Performance Level" parameter can be selected.
Decode Perf. Level
This parameter provides three levels of decode performance or "aggressiveness" for
Code 128 symbols. Increasing the performance level reduces the amount of required
bar code orientation – this is useful when scanning very long and/or truncated bar
codes. Keep in mind that increased levels reduce decode security.
When you double-tap on this parameter, a dialog box is displayed in which you can
enter a decode performance level of between 1 and 3.
