What cooking functions are available on the Teka HA 850, and which should I use for baking cakes?

The oven offers nine functions: Conventional, Conventional with fan, Grill, MaxiGrill, MaxiGrill with fan, Turbo, Lower element, Lower element with fan, and Grill and Lower element. For baking cakes and sponges, use the Conventional function to provide uniform heat for a spongy texture.
