Some models will allow metal pans.Check the owners manual and see what they recommend for yours.

But even the manual for your oven, which is available on line at the link you provided, says the following:
Microwave function only
Utensils and cooking containers used in a microwave oven
should be of a material that does not act as a barrier to
microwave energy. Generally this means that you should cook
in either (paper), plastic, glass or ceramic.
Metal pans reflect
microwave energy and inhibit cooking, and should not be
used....Metal containers, e.g. saucepans or frying pans should not
be used in microwave ovens. Nor should plates or vessels
with decorations be used since metal e.g. gold, might be part
of the decoration and such decorations will be damaged.
Small pieces of aluminiuum foil can be
used, but only to shield the areas that
would over-cook (e.g. for covering
chicken wings, leg tips and fish tails) but
the foil must not touch the side of the
oven as damage may occur.
It does say you can use metal baking tins (but not metal pots or pans) in the combination mode, but includes the following warning: "Metal tins can be used in the combination methods, however
if these are very deep, they will greatly reduce the efficiency,
as metal shields the microwave energy from the food."
Finally, it includes the following warning:
ARCING
If you see arcing, press STOP/CLEAR button and correct the problem.
Arcing is the microwave term for sparks in the oven. Arcing is caused by:
• Metal or foil touching the side of the oven.
• Foil not molded to food (upturned edges act like antennas).
• Metal, such as twist-ties, poultry pins, or gold rimmed dishes, in the microwave.
• Recycled paper towels containing small metal pieces being used in the microwave.
