I may be a little slow, and I found it difficult to figure out the user interface of the Xtar Vp4 Plus Dragon, even after looking at the nice reviews by stephenk and HKJ. The included instructions are a joke.

So I tried to gather the pertinent operating instructions to write down for myself. Could anyone confirm if I have this correct? Are there known firmware changes that might operate differently?

I will probably write myself an extended user manual, as I have a habit of forgetting details and like to be able to look them up in later years without having to hunt down articles on the internet.
