life expectancy of the appliance considerably reduced. In addition, its safety and proper
operation may also be affected.
 This appliance is intended for domestic or similar applications, such as
- in shops, offices and other similar working environments,
- in agricultural areas,
- by customers in hotels, motels etc. and similar establishments,
- in bed-and breakfast type environments.
 Caution: Any maintenance or repair work requiring the removal of any microwave radiation
protection cover represents a serious hazard to unqualified persons. This includes the
replacement of the special power cord or an interior light bulb. The unit must not be opened,
except by qualified personnel. If repairs are needed, please send the appliance to one of our
customer service departments. The address can be found in the appendix to this manual.
 This appliance is a group 2 class B ISM device. Group 2 contains all ISM devices (industrial,
scientific, medical) generating radio frequency energy and/or using radio frequency energy in
the form of electro-magnetic radiation to process materials; it also comprises spark erosion
devices. Class B specifies devices designed for domestic use, or any similar devices integrated in
the general power grid supplying domestic units.
The microwave function (Group II in compliance with EN 55011:1998+A1+A2)
Electromagnetic energy is generated inside the unit, causing the molecules in the food (mainly water
molecules) to oscillate and subsequently causing the food to become hot. Food with high water
content will therefore heat up faster than relatively dry food. The heat is generated gradually inside
the food. Any utensils, container or plates used are heated up only indirectly as a result of the food
temperature.
Always use suitable kitchen utensils:
 Do not place the food directly onto the glass turntable; always use a suitable plate or cooking
container. Make sure that the container does not protrude over the rim of the glass turntable.
 Metal objects are to be avoided since microwaves are reflected from metal surfaces and might not
reach the food to be cooked. Any metal in the oven could also cause sparks, resulting in possible
damage to the unit.
 As a general rule, cutlery or metal containers must not be used in the microwave oven. Some
food wrappings contain aluminium foil or wires underneath a layer of paper and are therefore
also unsuitable for use with microwave appliances.
Should the use of aluminium foil be recommended in a recipe, ensure that the food is tightly
wrapped in the aluminium foil (avoiding any air blisters). Ensure a minimum distance of 2.5 cm
between the aluminium foil and the interior walls of the oven.
 Always make sure that the cooking container or plate used does not contain any metal decoration
such as a gold rim or colour containing metal particles. Lead crystal objects are also not suitable.
Always make sure that no parts of the cooking containers used are hollow (e.g. the handles).
Porous materials may have absorbed water during cleaning and are again not suitable. Cooking
containers or utensils made of 'Melamine' plastic material absorb energy and are also unsuitable.
- Using the microwave function
- Containers made from heat-resistant glass or porcelain are particularly suitable for use in
microwave appliances.
- Plastic is suitable only if it is heat-resistant up to at least 180° C. Cooking bags etc. should be
punctured to be able to release any high pressure during cooking.
