Fisheries and Food) with microwave oven and food
manufacturers and indicates the ability of the oven
to heat small quantities of food (up to 500g [1lb
2oz]). It does not represent the general
performance of the oven.

cooking/defrosting press the MICROWAVE
POWER LEVEL key. The power level will be
displayed as long as the key is pressed. This does
not affect the programme or cooking time.

Water, sugar and fat in food absorb microwaves and
causes their molecules to vibrate. This creates heat by
friction, in the same way your hands get warm when
you rub them together.  
The outer areas of  food are heated by microwave
energy and the remaining portions by conduction.  It is
important to turn, rearrange or stir food to ensure
even heating.  Where recommended, allow food to
stand, this is not optional but is necessary to ensure
thorough cooking. It is particularly important for dense
food, such as joints of meat.

NOTES:
• Microwaves pass through non-metallic dishes and

utensils and heat the food inside the dishes. 

• Microwaves are reflected by metal. 
• The oven is lined with metal and has a fine metallic

mesh in the door to prevent microwave leakage.

• Metallic dishes are not suitable for microwaving. 
• Place convenience foods on a non-metallic plate.
• See SUITABLE COOKWARE, page 21-22.

NOTES:
• Your oven can be programmed up to 99 minutes, 90 seconds (99.90).

The oven cavity, door, turntable, rack, dishes and especially
the bottom grill heater become very hot. To avoid burns
always use thick oven gloves when removing food or the
turntable from the oven.

and odour will be given off. To avoid this happening
when food is being cooked, heat the top and bottom
grills without food for approximately 20 minutes.

• The rack is recommended for grilling small items such

as toast, bacon or steak. Place food directly on the
rack, in a flan dish or on a heat resistant plate on the
rack. Turn over halfway through grilling. See cooking
charts p16.

• If you cook whilst the energy save mode is set, at the

end of cooking the display will be               . And
after 2 minutes, the display will be blank.

• When browning or crisping foods in a casserole dish,

place directly onto the turntable.
