What does the oven function "Half Fan Grill" mean?

Same as Static Grill but for smaller quantities of food placed from rear to front in the centre for maximum results. You will often find however that the half function is the perfect size to brown the average family size dish, while half Static Grill is perfect for smaller quantities of food it is also perfect for melting the cheese on a large lasagne or oven bake. When using Half Static Grill always place the food in the centre of the oven on shelf 4 from the back of the oven to the front.
