I hear you Shadow. I should have known you would have already googled it. I have had the same problem with an iphone ripoff from China, and a few other items that came with dodgy/non-existent instructions.
I eventually sorted out how to do what I wanted to do with them, but it was a lot of googling, and trial and error with the device. There would no doubt be a concise/ well written set of instructions posted somewhere in cyberspace by someone who has nutted it out and posted their results for others. Its just a matter of finding them.
Still, you are in the right profession for that, so good luck again.
