You then need to configure the scanner to set a TAB terminating character by scanning the barcode below (this barcode also comes on the credit card that accompanies the scanner).
Your Netum scanner is now setup.
If you need to reset your scanner to factory defaults, scan the barcodes below.
Note, you will need to pair your scanner again with your tablet after this reset.
