Symbol Technologies STB3478 Barcode Scanner I have listed this as spares or repairs as I do not know how to test it. I plugged the base unit in to a USB socket and placed the handset on it and the lamps on the top of the handset started to glass red periodically. After a night on charge I came down and the same two lights are permanently light green. Take the handset off the base and pull the trigger and I don’t see it doing anything. So selling as spares or repairs, everything else that came out of this business has been in good working order though
