I wonder if anybody might know, where I might be able to aquire or download a copy of an owners manual for a Raymarine C80 multifunction display?

I've searched the web, but cant find one!

I bought the unit second hand, and to be quite honest, it's pretty srtaight forward, but I'd like it as there's one or two settings I cant quite sort out without it!

I hope somebody might know a site which I've not come across that might have one.

Thanks in advance,

Pedro
