for some reason, i'm not able to program our new bluetooth socket scanners to have a Tab. Before, I was able to scan a few barcodes to program them, but now, they aren't working. I've searched and searched, and downloaded the socket userguides and used the barcodes they had, but it still doesnt work. I need it to scan a barcode, then tab to the next line. We are using the CHS 7CI series.
