General notes
Always ensure that food is suffi-
ciently cooked or reheated. Many
factors will affect the overall cooking
time, including the size and amount of
food, its initial temperature, changes to
recipe and the shape and size of cooking container. Some foods may contain
micro organisms which are only de
stroyed by thorough cooking, therefore
when cooking or reheating foods, e.g.
poultry, it is particularly important that
food is fully cooked through (at over
70°C, for a minimum of 10 minutes). If
in doubt select a longer cooking or re
heating time.
-
-
-
-
It is important that the heat is al
lowed to spread evenly throughout
the food being cooked.
This can be achieved by stirring and/or
turning the food, and by observing a
sufficiently long standing time, which
should be added to the time needed for
cooking, reheating or defrosting.
-

Warning and Safety instructions
Always remember that cooking
times in a microwave oven are usu
ally considerably shorter than with tradi
tional methods of food preparation. Ex
cessively long cooking times can lead
to food drying out and eventually burn
ing, or could even cause it to catch fire.
There is also a danger of fire if
breadcrumbs, flowers, herbs, grains
etc., are dried in the microwave oven.
Always ensure that this type of proce
dure is supervised.
Exercise caution when cooking or
reheating food with a high sugar
content, e.g. Christmas pudding. If
heated for too long the sugar may
caramelise or ignite.
Do not use full power if you warm
empty dishes or dry herbs. The
lack or minimum amount of food could
cause damage to the appliance.
Do not leave the oven unattended
when cooking with oils and fats as
these can be a fire hazard if allowed to
overheat.
If smoke occurs in the oven, to
avoid fuelling any flame do not
open the oven door. Turn the function
selector to "0", or switch off at the mains
and remove the plug from the socket.
Do not open the oven door until the
smoke has dispersed.
Never heat undiluted alcohol in the
microwave oven as this can easily
ignite.
Do not heat up unopened tins of
food in the oven as pressure will
build up in the tin and it can explode.
This could result in injury or damage.
-
Food left in the oven to take advan
-
-
-
-
tage of residual heat should always
be covered to avoid it drying out, and
to avoid a possible build-up of conden
sation which could adversely affect the
oven interior.
Try to avoid the interior walls being
splashed with food or liquids con
taining salt. If it does happen wipe
these away thoroughly, to avoid corro
sion on the stainless steel surface.
Wear oven gloves when removing
the glass tray from the oven. If the
glass tray has a heavy load, pull it only
slightly towards you, and then hold
firmly at the sides as you take it out.
The glass dish and the rack take a
maximum load of 8 kg. Do not exceed this or the accessories may be
damaged.
Do not lean or sit on the open oven
door. This could damage the appliance. Take care in the region of the
hinges. An oven door can support a
maximum load of 8 kg.
When it is hot do not place the
glass tray on a cold surface, such
as a tile or granite worktop . It could
break. Place it on a pot rest or a wire
rack.
Under no circumstances use a
steam cleaner to clean this appli
ance. The steam could attack the elec
trical components and cause a short
circuit, or permanent damage to the
surface and to components, for which
the manufacturer of the oven cannot
accept any responsibility.

Warning and Safety instructions
Do not use the oven to heat up the
room. Due to the high temperatures
radiated, objects left near the oven
could catch fire.
When using kitchen appliances
connected to sockets near the
oven ensure that the cable cannot get
trapped in a hot oven door, which could
melt the cable insulation and be dan
gerous.
In countries which may be subject
to infestation by cockroaches or
other vermin, pay particular attention to
keeping the appliance and its sur
roundings in a clean condition at all
times.
Any damage which might be caused by
cockroaches or other vermin will not be
covered by the appliance guarantee.
Microwave function
Before serving remember to allow
sufficient standing time and then
always check the temperature of the
actual food itself after taking it out of the
oven. Do not be misled by the tempera
ture of the container which does not
necessarily give a correct indication of
the temperature of the food or liquid in
it. This is particularly important when
preparing food for babies, children,
and the elderly or infirm.
Never cook or reheat food or liq
uids in sealed containers or bot
tles. With baby bottles the screw top
and teat must be removed. Otherwise
pressure builds up which can cause
the bottle or container to explode pos
ing a severe risk of injury.
-
-
-
-
-
When heating liquids, the boiling
rod provided should be placed into
the container.
When heating liquids, milk, sauces etc.,
in the oven without the boiling rod, the
boiling point of the liquid may be
reached without the production of typical bubbles. The liquid does not boil
evenly throughout. This so-called 'boiling delay' can cause a sudden build up
of bubbles, when the container is removed from the oven or shaken. This
can lead to the liquid boiling over sud
denly and explosively. There is a dan
ger of burning. The formation of bub
bles can be so strong that the pressure
forces the oven door open. The user
could be injured and the appliance
damaged.
The boiling rod ensures that the liquid
boils evenly and that bubbles form at
an early stage during the operation.

Warning and Safety instructions
Do not use any containers or cut
lery made from or containing metal,
aluminium foil, lead crystal glassware,
temperature-sensitive plastics, wooden
utensils or cutlery, metal clips or wire
ties. Such items could be damaged, or
cause a fire hazard.
The rack supplied with the appliance is
designed to be compatible with micro
waves, and can therefore be used with
or without the microwave function.
The rack gets hot when operating
either the micwowave function or
the browning element, or both. There is
a danger of burning.
Eggs can only be cooked in their
shells in the microwave oven in a
specially designed egg-boiling device
available from specialist shops. Similarly, hard-boiled eggs should not be
reheated in the microwave oven as this
may lead to the eggs bursting, even
once they have been removed from the
oven.
Eggs can be cooked without their
shells in the microwave oven only if
the yolk membrane has been punc
tured several times first. The pressure
could otherwise cause the egg yolk to
explode.
Do not reheat food in the oven in
heat-retaining bags intended for
normal ovens. These heat-retaining
bags usually contain a thin layer of alu
minium foil which reflects microwaves.
This reflected energy can, in turn,
cause the outer paper covering to be
come so hot that it ignites.
-
-
-
Food with a thick skin or peel, such
as tomatoes, sausages, jacket po
tatoes, aubergines, should be pierced
or cut in several places to allow steam
to escape and prevent the food from
bursting.
Ovenproof earthenware can retain
-
-
a considerable amount of moisture.
Earthenware and porcelain containers
with hollow handles and lid knobs must
only be used in this oven if they have
vent holes, which allow the moisture to
escape. Without vent holes there can
be a pressure build-up, causing the
container to crack or shatter, with the
danger of injury.
Traditional oven functions:
Fan Heat, Grill
Caution - Danger of burning
When the oven is being used as a
traditional oven it can get very hot.
Great care should be taken to en-
sure that small children do not
touch the oven when it is being used.
External parts of the oven such as door
glass, handle vents and the facia panel
can become quite hot.
Wearing heat-resistant oven gloves
is recommended when placing
food in the oven, turning it or removing
it. When the Grill function has been
chosen, either solo or in a combination
programme the element becomes very
hot and there is a danger of burning.
-
10
Warning and Safety instructions
Wait until the element has cooled
down before lowering it for clean
ing.
Do not use force to pull it down as
this can cause the element to
break.
Bottling
Bottling should only be undertaken by
an experienced cook who has received
proper training in this method of pre
serving fruit and vegetables in an oven
or microwave oven, and understands
the implications of the chemical reac
tions involved.
The manufacturer cannot be held lia
ble for damage caused by non-com
pliance with these Warning and
safety instructions.

Caring for the environment
Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for disposal
and can normally be recycled.
Ensure that any plastic wrappings,
bags etc. are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation!
Rather than just throwing these materi
als away, please ensure they are of
fered for recycling.
-
-
Disposal of your old appliance
Old appliances may contain materials
which can be reclaimed or recycled.
Please contact your dealer, your local
waste collection centre or scrap mer
chant about potential recycling
schemes.
Before discarding an old appliance
switch off and disconnect it from
the power supply. This should be done
by a competent person. Cut off and
render any plug useless.
Cut off the cable directly behind the ap
pliance to prevent misuse.
Ensure that the appliance presents
no danger to children while being
stored for disposal.

Operating modes
Microwave h
Microwave cooking offers the benefits
of speed, convenience and nutritional
advantages when food does not require
browning or crisping.
Functional description
This oven is equipped with a magnetron a, which converts electrical energy into microwaves.
A stirrer fan b above the oven ceiling
distributes the microwaves evenly
throughout the oven interior, rebound
ing them off the walls so that they reach
and enter the food from all sides.
-
All food contains moisture molecules
which, when subjected to microwave
energy, start to oscillate 2.5 thousand
million times a second. The friction
caused by this vibration creates heat,
which first starts developing around the
outside of the food and then slowly
penetrates towards the centre. The
moisture, fat and sugar content of food
will affect the speed at which it is
cooked.
As heat is produced directly in the
food,
food can generally be cooked with
–
out adding much liquid or cooking oil
– cooking, reheating and defrosting in
a microwave oven is quicker than using traditional oven methods
– nutrients, such as vitamins and min-
erals, are generally retained
– colour, texture and taste of food are
not impaired
–
the surface temperature stays cool
enough to avoid browning.
-
In order for microwaves to reach the
food, they must be able to penetrate
the cooking utensil being used.
Microwaves can penetrate porcelain,
glass, cardboard and plastics but not
metal. Do not, therefore, use utensils
made of metal, or which contain metal,
for example in the form of gold or silver
trim. The metal reflects the microwaves
and this could lead to the creation of
sparks. The microwaves cannot be ab
sorbed.
-

Operating modes
Traditional oven functions
Fan Heat D
Grill n
These cook and brown the food.
Fan Heat D
The fan circulates heat constantly
around the oven, giving a very even
temperature throughout.
It sucks in the air, heats it over a ring el
ement and blows it back through the
carefully spaced openings in the back
panel.
As the heat is quickly transferred to the
food, it is not usually necessary to preheat the oven, except when roasting
sirloin or fillet or for foods such as puff
pastry and yeast mixtures which require
instant heat.
With Fan Heat food can be baked or
roasted on both levels at the same time.
Combination programmes
Microwave + Fan Heat h + D
Microwave + Grill h + n
The combination programmes enable
the grill or the fan setting to be used in
conjunction with the microwave facility.
A microwave power level and cooking
time are programmed together with ei
ther the grill or the fan to run simulta
neously.
This enables cooking times to be re
duced, yet a crisp, brown result can still
be achieved without compromising the
flavour or texture of the recipe.
In general when using combination
programmes, you should not set the microwave power level higher than 150 W
for baking, and not higher than 450 W
for cooking and grilling.
-
-
-
Grill n
Note that this function is best suited to
browning food and for grilling very thin
cuts of food.
As the element needs to radiate a high
heat in order to cook the food, it will
take several minutes after being
switched on to glow red hot and so pro
duce sufficient infra-red heat for grilling.
Pre-heat the with the oven door closed
for approx. 5 minutes before starting to
cook.

With new appliances there is usually a
smell during the first use. It is dispelled
more quickly by using a high tempera
ture as follows:
Run the oven on the Fan Heat D setting for at least an hour:
^
Select Fan Heat D with the function
selector.
The cooling fan starts up and the oven
interior light comes on.
Turn the temperature selector to
^
200 °C.
Only turn the temperature selector
clockwise and then back again anticlockwise. Do not force it past the
resistance. Otherwise it could be
damaged.
The oven begins to heat up. The indicator light on the control panel stays alight
while the oven is heating up.
Ensure the room is well ventilated
during this process.

Suitable containers for microwave ovens
Microwaves
are reflected by metal,
–
– pass through glass, chinaware, plas-
tic and card,
–
and are absorbed by food.
Material and shape
The material and shape of containers
used affect cooking results and times.
Heat distribution is more even in round
and oval shaped dishes than in rectan
gular containers, providing better re
sults.
Metal
Metal containers, aluminium foil and
metal cutlery, or china with metallic
decoration such as gold rims or co
balt blue must not be used in micro
wave mode.
The metal reflects the microwaves, hindering the cooking process.
Exceptions:
If recommended by the producer, precooked meals packed in aluminium foil
containers can be defrosted and reheated in the microwave oven. Important: remove the lid first. However, as
food is only heated from the top, it is
better to remove the food from the alu
minium foil container and transfer it to a
dish suitable for a microwave oven. The
heat distribution will be more even. If
sparks and arcing occur when using a
metal container, stop and transfer the
food to a microwave safe container.

-
For even defrosting and to avoid over
cooking unevenly shaped cuts of meat,
poultry or fish, small pieces of alu
minium foil may be used to mask wingtips or other thin parts for the last few
minutes of the process.

Suitable containers for microwave ovens
Decorated earthenware is only suitable
Make sure that the aluminium foil is
at least 2 cm from the oven walls at
all times. It must not touch the walls.
Metal meat skewers or clamps should
only be used if they are very small in
comparison to the size of the cut of
meat.
The rack supplied with the appliance is
suitable for use in a microwave oven.
Do not place the rack on the oven floor.
The rack can get hot.
Glassware
Heat-resistant glass or ceramic glass
are ideal for use in the microwave oven.
Crystal glass contains lead which could
cause the glass to crack. Glass dishes
with a milled rim are subject to the
same risk. Both are unsuitable.
Earthenware
Although some ovenproof earthenware
can be used in a microwave oven it
may contain a considerable amount of
moisture, causing it to become hot dur
ing use. It is normally advisable to
avoid using it in a microwave oven.
if the decoration is beneath an all-over
glaze.
Earthenware can get very hot, and
may crack.
Porcelain (chinaware)
Porcelain is suitable, however contain
ers with hollow handles and lid knobs
must only be used if they have vent
holes, which allow the moisture to es
cape. Without vent holes there can be a
pressure build-up, causing the con
tainer to crack or shatter, with the dan-
ger of injury.
Do not use porcelain with gold or silver
edging or items with hollow knobs or
handles as insufficient ventilation may
cause pressure.
Glazes and colours
Some glazes and colours contain
metal.
This makes them unsuitable for use in a
microwave oven.
-

-
-
Earthenware containers with hollow
handles and lid knobs must only be
used if they have vent holes, which al
low the moisture to escape. Without
vent holes there can be a pressure
build-up, causing the container to crack
or shatter, with the danger of injury.

Suitable containers for microwave ovens
Plastics
Plastic containers must only be used for
Microwave mode alone and not in con
ventional oven mode.
Plastics must be heat-resistant to a min
imum of 180 °C. Otherwise the plastic
may melt and fuse with the food.
Special plastic utensils, designed for
use in microwave ovens are available
from good retail outlets. Melamine ware
is not suitable as it absorbs energy and
heats up. When purchasing
plasticware, make sure that it is suitable
for use in a microwave oven.
Disposable containers, such as trays
made from polystyrene, can only be
used for very short timed warming and
reheating of food.
Plastic boiling bags can be used for
cooking and reheating. To reduce the
risk of the bag bursting, they should be
pierced first so that steam can escape
and prevent a build-up of pressure.
Roasting bags and -tubes
Roasting tubes should be about 40 cm
longer and roasting bags about 20 cm
longer than the food being roasted, and
carefully tied with string. Turn the ends
over and secure them. Holes should be
made according to the manufacturer's
instructions.Do not use metal clips or
wire ties, even if bound by paper. There
is a danger that they will ignite when
heated.
Wood
Wooden dishes are not suitable.
Moisture contained in the wood evapo-
rates when exposed to microwave energy, causing the wood to dry and
crack.
Disposable containers
Only those plastic disposable containers which are specified by the manufacturer as suitable for use in a microwave oven may be used.
Do not leave the oven unattended
when re-heating or cooking food in
disposable containers made of plas
tic paper or other inflammable mate
rial.
Disposable containers are not always
recyclable or degradable.

Testing dishes for their suitability
If in doubt as to whether glass, earthen
ware or porcelain plates or dishes are
suitable for use in a microwave oven, a
simple test can be performed:
Place the item you wish to test in the
^
centre of the oven, fill a suitable glass
with water and also place this in the
oven.
Shut the door.
^
A microwave oven process cannot
be started until the door is closed.
The c symbol appears above the dot.
Press the Start/Stop button.
^
The oven interior light comes on. The
time entered counts down in the display
in second steps. The c symbol stays
on constantly.
If a crackling noise is heard accom
panied by sparks during the test,
switch off the appliance immediately.
Turn the function selector to the "0"
position. Any crockery which causes
this reaction is unsuitable for use in
the microwave oven.
At the end of this period a beep sounds
three times and the c symbol flashes.
Press any button to cancel them. The
time of day reappears in the display
and the oven interior light goes out.
The water in the glass should be warm,
but the dish cool. If the dish is very hot
and the water is cold, it would be unwise to use the dish.
-
^
Select Microwave h with the function
selector. The cooling fan will run.
The display will show a suggested
power level of 900 W.
^
Press the g button.
0•00 appears in the display for
approx. 4 seconds.
While it is visible enter a time of 30 sec
onds with the "+" control.

If any doubt exists about the suitabil
ity of containers, please contact the
supplier.
This test cannot be used to check
whether items with hollow knobs or han
dles are suitable for use in a microwave
oven.
