▲WARNUNG Warning
▶ Do not leave the device unsupervised when it is in operation, so that you can intervene quickly in the event of dangers.
17.1 Principles of microwave cooking
- The power levels and time required for cooking / warming up food items depends on the starting time, the quantity and the type and consistency of the food, etc. Use the shortest indicated cooking time and extend the cooking procedure as necessary.
- Arrange the food carefully. Position the thickest areas on the external edge of the bowl.
- Cover the food while it is cooking. Lids protect against spatters and also contribute towards cooking/warming up the food evenly.
- During warming, the food should be turned, rearranged or stirred repeatedly, in order for the temperature to be distributed evenly.
- Any existing germs in the food are only killed off if the temperature is sufficiently high enough ( >70^ ) and if the time used is sufficiently long enough ( >10 min ).
-
Foods with a firm skin or shell, such as tomatoes, sausages, potatoes in the skin, eggplants must be pierced or punctured repeatedly so that any developing steam can escape and so that the food does not burst.
-
Eggs without their shell may only be cooked in the microwave if the skin of the egg yoke has been pierced repeatedly first. Otherwise, the egg yoke can squirt out with excessive pressure after cooking.
- Rearrange layers of foods such as meat balls from top to the bottom and from the middle to the outside edge.
17.2 Operating modes:
The unit is to be operated in various operating modes. The following list shows the operating modes that are possible with the device:
◆ “Microwave” mode
This operating mode is suitable for the normal reheating of food.
◆ Defrost
This operating mode is suitable for defrosting frozen food. You can set desired time.
17.3 Information on microwave cookware
The ideal material for microwave cookware is permeable for microwaves and allows the energy to penetrate the container and warm up the food.
Please observe the following tips when selecting the correct cookware:
Microwaves cannot penetrate metal. Therefore, you should not use utensils made of metal or cookware with metal trim.
For microwave cooking, do not use any products made from recycled paper, as they could contain tiny metal fragments, which could cause sparks and/or result in fire.
The following table is intended as a basis for selecting the correct cookware:
| Cookware Microwave Cookware Microwave | |||
| Heat-resistant glass dishes | √ | Kitchen roll | ✕ |
| Non heat-resistant glass dishes | ✕ | Metal sheet | ✕ |
| Heat-resistant ceramic dishes | √ | Metal rack; metal container | ✕ |

19 Defrosting
If, for example, you would like to start a three-minute defrosting setting, then proceed as follows:
- Press the "Power level" button three times.
- "DEF" will appear on the display.
- Press the 3, 0, 0 buttons one after another.
- Press the "Start" button.
19.1 Defrosting frozen food
- When defrosting a heavy piece of high-fat meat, you should only warm it up in the microwave for a short time and then place it in a container at room temperature. Alternatively, you can heated it at short intervals with breaks in between.
- Food should be turned over regularly during defrosting to ensure that it thaws evenly.
-
Simultaneous full defrosting of food items of different thicknesses and shapes using a microwave is not recommended because this can result in uneven thawing.
Melt water can cause some areas of the food items to heat up while others remain frozen.
We therefore recommend that only approx. 70% of the defrosting process is carried out using the microwave. -
Any ice which has formed on food should be removed gradually.
- When defrosting a whole chicken, the thinner areas should be wrapped in aluminium foil. This will result in them being heated more slowly than thicker areas. Thicker areas can be wrapped in aluminium foil at the sides for even heating by the vertical microwaves during defrosting.
19.2 Tips & notes
- Cover food items to speed up the heating process, to prevent them drying out and to avoid fat splashing onto the cooking chamber.
This does not apply for dishes which should stay crunchy, such as biscuits or breaded items.
- A variety of factors will affect cooking time:
| Shape The thicker the item, the longer the cooking time | |
| Weight The heavier the item, the longer the cooking time | |
| Density The denser the item, the longer the cooking time | |
| Starting temperature | The lower the starting temperature, the longer the cooking time |
| Moisture content The drier | the item, the longer the cooking time |
20 Cleaning and Maintenance
This chapter provides you with important notices with regard to cleaning and maintaining the device. Please observe the notices to prevent damages due to cleaning the device incorrectly and to ensure trouble-free operation.
20.1 Safety information
▲VORSICHT
Attention
Please observe the following safety notices, before you commence with cleaning the device:
The device must be cleaned regularly and any food residues must be removed. Insufficient cleanliness of the device can lead to the destruction of the surface, which for its part can have a negative impact upon the service life of the device and can lead to a dangerous condition of the device as well as fungal and bacterial contamination.
▶ Switch the oven off prior to cleaning it and unplug the plug from the wall power outlet.
The cooking chamber is hot after it is used. There is a danger of burns! Wait until the device has cooled down.
▶ Clean the cooking chamber after use as soon as it has cooled down. Extended waiting unnecessarily complicates cleaning and can make it impossible in extreme cases. Excessive accumulations of dirt can even damage the device under certain circumstances.
▲VORSICHT Attention
▶ If dampness penetrates into the device, this can damage the electronic components. Please ensure that no liquid can enter the interior of the device through the ventilation slots.
▶ Do not use any aggressive or abrasive cleaning agents or solvents.
▶ Do not scrape off stubborn dirt with hard items.
▶ Because of the hazards involved in repair or maintenance work for which the radiation safety cover must be removed, any such work may only be carried out by a skilled and qualified specialist.
20.2 Cleaning
◆ Cooking chamber and inside of door
Keep the cooking chamber of the oven clean. Wipe off any spattered or spilt food from the walls of the cooking chamber with a damp cloth. If the oven is excessively dirty, you can use a mild cleaning agent.
Wipe the door, window and the door gaskets with a damp cloth, to remove any spatters and spilt food. Residues on the door gasket can mean that the door does not close properly any more, which will cause the microwaves to escape.
Wipe off any steam, which has settled on the oven door, with a soft cloth. This may be the case if the device is used in an extremely damp environment and is normal.
After cleaning the interior space, leave the oven door open until the interior of the device is completely dry.
Cleaning hint – If there are cooked food residues stuck to the inside walls of the oven, there is an easy way to clean these: Place half a lemon into bowl, add 300 ml water and microwave this for 10 minutes at full power. Then simply wipe the inside of the appliance clean with a soft and dry cloth.
◆ Front of device and operating panel
Clean the front of the device and the operating panel with a soft, slightly damp cloth.
Please bear in mind that the operating elements do not get wet. Use a soft, damp cloth for cleaning.
HINWEIS Please note
Leave the oven door open to prevent the device from being re-started accidentally.
▶ Make sure that no water gets into the ventilation slots.
▶ After cleaning, you can use a dry, soft cloth to dry and polish the surface.
◆ Exterior housing
Clean the exterior surfaces of the device with a damp cloth.
