OK, don't laugh, it has been a good scanner for me. Recently, it stopped recieving anything. I realized that the display was lit, but no information was displayed. First question: has anyone else experienced this? Second question: Does anyone know where I can obtain a servise manual for it. I have looked around, but I think the 600XLT was a custom produced machine for a certain vendor. Any help will be greatly appreciated. Contact me at : firstname.lastname@example.org.
