Enabled
Set this parameter to on to enable “Code 128”.

Enable GS1-128/GS1 US
Previously UPC/EAN and UCC, these types of bar codes include group separators and start 
codes.

Enable ISBT 128
To successfully scan this variation, “Enable ISBT 128” must be set to on.

Decode Performance
If this parameter is set to on, one of three decode levels assigned to the “Decode Perfor-
mance 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.

Field Size/Char
Refer to page 137 for details.

Enabled
Set this parameter to on to enable “EAN 13”.

Prefix Char
This character, if non-zero, is added before a successfully decoded bar code. Press the key 
you want to insert in the dialog box attached to this parameter. The ASCII/Unicode key 
value of the keypress is displayed.
