Automatic programmes 
Follow the instructions in the display.
Fan Plus 
This function is suitable for roasting
meat and poultry that needs to be well
browned.
Because the fan distributes the heat
around the oven compartment straight
away, you can use a lower temperature
than you would with the
Heat  function.
Conventional Heat 
Use this function for cooking traditional
recipes. If using an older recipe or
cookbook, set the oven temperature
10 °C lower than that recommended.
This will not change the cooking
duration.
Use the
Bottom Heat
towards the end of the cooking
duration to brown the base of the
food.
Do not use the Intensive
Bake  function for roasting as the
juices will become too dark.
