I am grateful for any advice.
That's a screenshot of the instructions online, which I also have as a paper version. The quick set up guide is even less helpful in terms of explaining how to do it, which is why I searched online and found the link earlier about taking a moment to get it the right way up.
I've also remembered to check youtube but I've not found anything helpful. While I've been typing this I've noticed that the full instruction book refers to some online beginners' guides so that's my next step.
With anything like this I try to be aware of my limitations but I am capable of following clear instructions. It's a pity that the geniuses who produce kit with almost magic powers lack the basic communications skills to explain how to use it.
