OEM user manuals are usually written early on during the development of a scanner before it even exist. Just like computer software manuals, they were written by programmers that know the software inside and out and they often assume a lot. The manuals are often written by people that don't even speak or understand English and they need to be translated. The SDS100 was designed in Japan, manufactured in Vietnam, and supported by a Paul Opitz who was going though a very serious battle with cancer at that time and during it's release. Things were destined to be left out, misunderstood, and even left to the imagination.Take a look at message 6 of this thread and you'll quickly learn why "read the manual' is often the wrong answer

The answer I often see here on RR is not "read the manual" rather a link to "Easier To Read" manuals, and as you said yourself, Youtube instructional videos. When I have referred a user to the manual, I also noted the page number that contains the information they either missed, or didn't read to begin with.
