In the following example I will show you how to programme your oven with micro power
convection temperature 200°C for a cooking time of 25 minutes.
Your oven has a combination cooking
feature which allows you to cook food
with heater and microwave at the same
time or alternately. This generally means
it takes less time to cook your food.
You can set three kinds of micro power
level(180,270 and 360W) in combi mode.
