PDF document for the SF064VT2 part, ADV suffix, around 178 KB, probably an advance or general specification for the module. It complements the separate VGA and INV sheets issued for the same base number. Such specifications typically give mechanical dimensions, electrical characteristics, the interface connector layout and operating conditions. Use it to confirm fitment and supply requirements when repairing or replacing the unit, and make sure the label reads SF064VT2 rather than SF064VT1, which has its own set of files.
