Hi, I've purchased the above model as a demo through ebay. Item is in excellent order, but came without any CD etc. I've downloaded a manual which is labelled as "X1160 / X1260", but there's no reference to the "Z" on the end, and I'm not sure whether it's the right one. Acer product page here: http://global.acer.com/products/projector/x1160Z.htm Help appreciated - thanks.
