Enabling 2-D Scanning:
The scanner default settings do not enable 2-D barcode reading ability. In order to
enable this option, follow these steps:
Scan the barcodes below to enable PDF417 and MicroPDF417. These are both
types of 2-D barcodes.
Now scan the barcode below to change the scanning pattern. Using this
scanning pattern will allow you to read 2-D barcodes (you can still read 1-D
barcodes also).
