Elitech 1300W convection oven: How to set it for ...

Question

My instruction manual neglects to even mention the great self cleaning function for my Elitech 1300W convection oven. I can't find any helpfull information on line for my self. I would like to know how to set it to the self cleaning mode. I have seen it advertised and shown on tv bidding but it was a different model to the one I have just bought. Can any body help to confirm the instructions to me for self cleaning function for Elitech 1300w convection oven,  which I now have. Thank you.
