Specification PDF for the SF064VT1 part, ADV suffix, roughly 218 KB, apparently the general or advance sheet in a set that also includes VGA and INV files. Such documents usually list outline dimensions, mounting points, interface connectors, electrical ratings and environmental limits. Repair technicians use it to confirm supply voltages at the connector and to judge whether a replacement unit is mechanically and electrically compatible. Check that the label reads SF064VT1, as the VT2 version is documented separately.
