Have a Pro668 that displays this error code on startup : 00037b40 , 3-04, and 0003. Cannot turn power off, have to remove batteries. Tried to reformat sd card and tried new sd card, but computer does not recognize scanner. Tried to reconfig but again scanner not recognized. Any idea where I can find error code description, or how to proceed ? USB cable works in programming other scanners. Working with Windows8. Thanks for any advice !
