Character subset for the
Text
scan type in English:
By using a specific subset of characters, the software eliminates the
chances of recognition errors. For example, if you select the reading
mode
Numeric
, you limit the set of recognized characters to
numeric symbols only. By doing so, no confusion can possibly be
made between "5" and "S", ""9" and "g", "8" and "B", etc. as the
software automatically interprets the characters as figures.
You can also by yourself go one step further and
customize any of
the proposed subsets
of characters. You can create a character
subset that exclusively contains those symbols you want to
recognize. As an example, if you want to read amounts given in
dollars exclusively, select the reading mode
Numeric
, then limit the
character set to figures, punctuation and the "$" sign, and eliminate
all other unnecessary symbols.
To customize a character subset:
•
In the
Application
window, first select a type of data to be read
(

read (
Language
field). The subset of characters proposed for
reading such data will be automatically activated.
