Decode Performance
If this parameter is enabled, one of three decode levels can be chosen in the “Decode
Performance Level” parameter.
Decode Perf. Level
This parameter provides three levels of decode performance or “aggressiveness” for
Code 39 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.
