So... new kitchen includes a Neff microwave/grill combination oven. The power levels are various defrost settings and then 600 or 1000W - there doesn't seem to be any way to set an intermediate power level.
But everything gives instructions for 750W or 850W (that's what my old one was). Should I use 600 for proportionately longer or 1000W for correspondingly less? Or does it depend what I'm zapping.
Thanks
