I finally located a manual on the web. And not from the seller or Danmini. I contacted Damnimi twice - without reply. As I said earlier, I can get a refund but not for the postage, and postage for me would cost about £22 stg. Paypal adjudicated in my favour but they couldn't force the seller to pay the postage.
I am very tempted to send them back a package of feathers, via registered post. Paypal would see that the package was delivered and would give me the refund. I'd then have the system and a smile on my face.
