Poor littly Gussy has a bad case of the flu with a middle ear infection. He's a very unhappy sick little boy. He's having really high temperatures and we are having trouble getting them under control even with panadol, neurofen and antibiotics.

We have a Braun Thermoscan thermometer. For some reason it has flipped from reading in celsius to farenheit. We can't seem to work out how to flip it back to celsius. Does anyone have any idea how to change it back to reading in celsius?
