10 - 10 Symbol LS4208 Product Reference Guide

Unknown characters are characters the decoder does not recognize. When Ignore Unknown Characters is 
selected, all bar code data is sent except for unknown characters, and no error beeps sound. When Convert Error 
on Unknown Characters is selected, bar codes containing at least one unknown character are not sent to the 
decoder, and a convert error beep sounds.

Scan a bar code below to select a leading margin duration.
