Microwave oven function:  
In a conventional oven the heat radiated by the  
resistances or gas burners, slowly penetrates the food  
from the outside to the inside. There is, therefore, a  
great loss of energy in the heating of the air, oven  
components and recipients.  
Most food contains water, whose molecules vibrate  
with Microwaves.  
The friction between the molecules generates heat,  
which causes a temperature rise in the food, defrosting  
it, cooking it or keeping it warm.  
On the other hand, in microwave ovens the heat is  
generated in the interior of the food itself, heating it  
from the inside outwards. There is therefore no loss of  
energy as the air, interior walls of the oven and  
recipients (when adequate) do not heat up with  
microwaves.  
As the heat is formed inside the food:  
- It may be cooked with little or no liquid or fat;  
- Defrosting, heating or cooking in the microwave oven  
is quicker than in a conventional oven;  
- Vitamins, minerals and nutritive substances are  
preserved;  
Microwave ovens have the following advantages:  
The Microwaves pass through porcelain, glass,  
cardboard and plastic but not through metal.  
Therefore, recipients made of or containing metal  
should not be used in the microwave oven.  
1. Save on cooking time: in general there is a 3/4  
reduction of the cooking time than with conventional  
methods.  
2. Ultra-quick defrosting that prevents bacteria  
development.  
The Microwaves are reflected by the metal…  
3. Electricity saving.  
4. Maintaining the nutritive value of the food due to the  
cooking time reduction.  
5. Easy cleaning.  
In the microwave oven there is a high voltage valve  
called "Magnetron" that converts electric energy to  
Microwave energy. These electromagnetic waves are  
conducted to the inside of the oven cavity by means of  
wave-guide and spread by a mode stirrer or by a  
turntable.  
…they pass through Glass and Porcelain…  
Inside the oven, the Microwaves spread out in all  
directions and are reflected by the metallic walls,  
penetrating the food evenly.  
…and they are absorbed by the food.

During Operation…  
Working with Microwaves  
The microwave oven door may be opened at any time  
during the cooking operation, in which case:-  
Before using any dish, make sure that it is appropriate  
for use in microwaves (SEE ADVICE ON THE USE OF  
UTENSILS AND RECIPIENTS).  
-
The production of microwaves is immediately  
interrupted;  
Always make a slit in the food's shell before cooking it.  
- The Timer is automatically stopped, indicating the  
remaining cooking time.  
Whenever heating liquids use a recipient with a large  
opening to allow the vapour to escape.  
Then, if you wish you may:  
Remember that…  
- Stir or turn the food, to improve uniform cooking;  
- Change the Microwave power level by pressing the

3. Less dense foods cook faster.  
- Change the operating time left by turning the  
ROTATING KNOB.  
4. An even distribution of the food in the oven  
guarantees better results. The cooking of different  
types of foods simultaneously is possible by placing  
the dense food in an outside circle and the less dense  
in the centre of the plate.

Precautions and Advices  
General security  
Eggs with their shell and whole boiled eggs shouldn’t  
be warmed up in microwave ovens as they may  
explode, even after microwave heating has ended.  
! If the door or the door hinges are damaged, the oven  
should not be switched on until repaired by a qualified  
technician.  
Only use utensils that are suitable for use in  
microwave ovens. Do not use any metal utensils inside  
the oven unless they were supplied with the oven and  
for that purpose.  
! It is dangerous for anyone, except a qualified  
technician, to tamper with the apparatus or try to repair  
it in any way by removing any lid or covering which  
assures protection against the exposure to microwave  
energy.  
Do not warm up liquids or other food in closed  
recipients as they may explode.  
! Liquids and other food should not be heated in  
airtight recipients as these can explode.  
Do not warm up pure alcohol or alcoholic drinks.  
FIRE DANGER.  
! Children should only be allowed to use the oven  
without adult supervision if they have been given the  
appropriate instructions so that they can use the oven  
safely and understand the dangers of its incorrect use.  
When in doubt, choose short periods to cook heat or  
defrost food with microwaves. With long cooking  
periods the food may become dry and even begin to  
burn.  
! When the microwave oven is operated in the  
Combination mode (Microwaves + Grill), children  
should only be allowed to use the unit under adult  
supervision due to the high temperatures generated.  
Do not use the microwave oven for anything other  
than warming, cooking or defrosting food.  
Do not operate the microwave oven without its tray  
nor when empty.  
! The microwave oven should be cleaned regularly and  
any food deposits removed (please see the chapter on  
Oven Maintenance for details). Failure to maintain the  
oven in a clean condition could lead to deterioration of  
the surface that could adversely affect the life of the  
appliance and possibly result in a hazardous situation.  
Keep the microwave oven ventilation holes open.  
Never cover any air vents or openings.  
Eliminating  
• Eliminating the packing materials: use the right bins  
when discarding all of packing materials. This will  
ensure that the packaging materials are recycled.  
When heating food in plastic or paper recipients,  
check the oven frequently in case they ignite.  
The European Directive 2002/96/EC on Waste  
Electrical and Electronic Equipment (WEEE), requires  
that old household electrical appliances must not be  
disposed of in the normal unsorted municipal waste  
stream. Old appliances must be collected separately in  
order to optimize the recovery and recycling of the  
materials they contain and reduce the impact on  
human health and the environment.  
If any smoke is detected, then switch off the oven or  
disconnect it and keep the door closed in order for any  
flame to die out.  
After warming up baby bottles or baby food jars stir  
or shake its contents and check the temperature  
before feeding, to avoid burns.  
Warming up drinks in the microwave oven may result  
in a delayed eruptive boiling; therefore one should be  
careful when handling the recipient.  
The crossed out “wheeled bin” symbol on the product  
reminds you of your obligation, that when you dispose  
of the appliance it must be separately collected.  
Consumers should contact their local authority or  
retailer for information concerning the correct disposal  
of their old appliance.

Practical advices  
! This type of dish may heat considerably.  
Use heat resistant ovenware made of glass, glass,  
ceramic, and porcelain, ceramic or heat-resistant  
plastic. These materials do not block the microwaves.  
Painted glazed ceramic dishes may be used if the  
painting is done under the glaze.  
This is not the case with ovenware made of metal.  
The microwaves are obstructed which means that the  
food in closed containers remains cold. Ensure that  
any metal objects – e.g. a spoon – are at least 2 cm  
away from the oven walls and the inside of the door.  
The glass on the inside of the door could be damaged  
by sparks.  
Many glazes and colours contain metallic substances.  
If this is the case they should not be used in the  
microwave as they may be damaged.  
Recipients with silver and gold glazes may go dark.  
! Plastic dishes should be heat resistant (at least 180°  
C) or they may be deformed when used in the  
microwave. Melamine dishes are not suitable for use in  
the microwave as they heat up too much  
To cook or defrost pieces of meat of irregular sizes,  
you may cover the thinner parts with tin foil, which  
should be kept at least 2 cm away from the oven walls,  
otherwise these may cause an electric arc.  
To cook or heat food in plastic bags, they should be  
perforated to allow vapour to escape thus preventing  
the bag from bursting.  
Metal spits may be used as long as they are smaller  
than the pieces of meat.  
Crystal contains a percentage of lead, which may  
cause it to crack if used in the microwave oven. The  
same may happen to glass dishes with jagged edges.  
! Wooden recipients should not be used in the  
microwave. Wood contains water, which evaporates  
and may cause the recipient to crack.  
! Porcelain dishes may be used but they should not  
have hollow handles. Humidity may be formed inside  
the hollow handles, which will causes an increase in  
pressure that may cause them to break.  
10  
 
Microwave Oven Maintenance  
The use of glass lids, plastic lids or plastic film is  
advisable because:  
If in doubt about the use of glass, glazed ceramic or  
porcelain dishes in the microwave oven, do the  
following test:  
1. They prevent the release of excessive vapours  
especially when cooking for longer periods.  
- Place the empty dish and a glass of water inside the  
microwave oven;  
2. They increase the speed of heating food.  
3. They prevent the food from drying up.  
4. They prevent the loss of the food aroma.  
- Close the door;  
- Set the Power Level Selector at maximum power;  
- Adjust the timer to 1 minute;  
The lids should have holes to avoid pressure. Plastic  
film should be perforated.  
! If during this test you hear any noise along with  
Baby bottles, baby food jars and other similar  
recipients should be warmed up without lids as they  
can burst.  
sparks, turn off the oven immediately.  
Any kind of cookware that has this kind of behaviour  
or is very hot when removed from the oven should not  
be used in the microwave oven.  
! Glazed ceramic dish recipients contain many  
water molecules and heat a lot, but can be used in  
the microwave oven.  
If in doubt, contact the supplier of the cookware, and  
make sure that they are appropriate for microwaves.

Remove the plug from the socket  
Light Replacement  
Make sure that the oven is unplugged before cleaning  
the oven.  
The light bulb may only be replaced by the Technical  
Support Service.  
Don't use abrasive cleaning products.  
Cleaning  
Outside  
1. Clean the outside surface with neutral detergent,  
lukewarm water and dry it with a damp cloth.  
2. Avoid water from entering the oven ventilation holes.  
Inside  
1. Clean the oven walls with a damp cloth after each  
use.  
2. Avoid water from entering the ventilation holes in the  
oven's interior.  
3. If some time has passed by since the last cleaning  
and the oven's interior is dirty, place a glass of water  
on the tray and switch on the oven for 4 minutes on the  
highest setting. Moisture will form on the oven walls,  
which will be easily cleaned.  
4. The tray can be washed with regular dish washing  
detergent or in the dishwasher.  
Door, door seal, and oven front  
1. These parts should always be clean, especially the  
contact surface between the door and the oven front,  
to prevent microwave leakage.  
2. Use neutral detergent, lukewarm water and dry the  
surface with a soft cloth.  
12  
 
Solving Problems  
Cord Replacement  
Repairs or interventions carried out by an unqualified  
serviceman can cause dangerous situations.  
If the cord is damaged, it should be replaced by the  
manufacturer, authorized agents or qualified  
technicians in order to avoid any dangerous situation  
and also because special tools are required.  
Every and any kind of repair or intervention should  
be done by the manufacturer, authorized agents or  
qualified technicians.  
If you detect any abnormalities in the oven, check the  
following before you contact T.A.S:  
1. Check if the outlet into which the oven is plugged  
has power. To do so, plug another appliance into the  
same outlet and check if it works.  
2 If the oven lamp switches on, but the food does not  
heat up, check if the door is well closed (if the door is  
not properly closed, no microwaves will be produced).
