SOURCE: 4 beep error when scanning barcode

The four beep error is a communications error. Usually it indicates the scanne is not configured properly. If the scanner is connecting with the CBA-K01-S07PAR cable and you are using a PS/2 keyboard you should have scanned the IBM PC/AT barcode from Adobe page 56 of 342 of the LS2208 Product Reference Guide.

If you do not have a PS/2 keyboard attached and are using a USB to PS/2 adapter you should scan the IBM AT Notebook from that same page. If the scanner does not start working immediately you may have to reboot your system. If the scanner still does not work the CBA-U01-S07ZAR USB cable might be a better choice.

If you are not connecting with either of these cables and are still getting the four beep error a call to the Motorola support center may be in order. Their phone number is 800-653-5350.

Microsoft Excel can print bar-code labels. I did this for my office for our stock room and they work with every bar-code reader I've used so far.
