UX of le Grill

After a sleepless night, I decided to give up on trying to make it to the land of nod and get up and do some work. After a few hours I decided it was breakfast time, and I could have a nice cooked breakfast before heading to work. Being in the new house, I was working with an oven I'd never come across. I decided to grill an English muffin and upon looking at the nob on the oven it was not evident at all what symbol was what. I clicked them around a bit, putting my hand in the oven to see what was on and no luck. I ended up having to get out the oven instructions (quoting The Simpsons "le grill - what the hell is that!") and decode what the funny symbols were meant to be.
