Why am I only allowed to cook at one level in the Dialog oven in the M Chef operating modes?
M Chef uses a combination of electro-magnetic waves and a conventional type of heating for cooking purposes.
Cooking is limited to one level because the electro-magnetic waves are shielded by metallic components.
The upper baking tray would shield the lower baking tray. The food on the lower baking tray would not be cooked sufficiently.
Consult the operating instructions for further information.
