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 ori-
entation – 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 .
