1.13 NEGATIVE BARCODES

Normally, barcodes are printed with the color of the bars darker than that of the spaces.
But for negative barcodes, they are printed in the opposite sense just like negative films.
The spaces of negative barcodes are printed with a color darker than that of the bars.
You can configure the scanner to be able to read negative barcodes.

1.14 EFFECTIVE DECODING AREA
By default, the effective decoding area is 100% covered by the scanned area. However,
you may narrow down the decoding area to prevent reading the wrong barcode when a
number of barcodes are printed closely. The scanner will only read barcodes that appear
in the effective decoding area.
Read the barcode "Centering On" and specify the percentage to narrow down the
decoding area. For example, read "Left 10%" and then "Right 30%" for the scanner to
decode barcode "A" only.
