Fuse locations

[Cadmaster]

I tried to use a 230v inverter power pack (made specifically for vehicles) - it didn't work and I now have lost power to the 12v socket (cigar lighter) - I assume a fuse has blown. I cannot believe that the Owner's Manual does not list the fuses. The diagram inside the lid of the under-bonnet box only has cryptic acronyms - is there an explanatory diagram or list somewhere?

Also, I cannot see how to remove the under-dash cover to access the other fusebox. I can see a tab near the front, but it doesn't want to release - is there another fixing I haven't seen?
