Short Cooking Times
As microwave cooking times are much shorter
than other cooking methods it is essential that
recommended cooking times are not exceeded
without first checking the food.
Cooking times given in the cookbook are
approximate. Factors that may affect cooking
times are: preferred degree of cooking, starting
temperature, altitude, volume, size and shape of
foods and utensils used. As you become familiar
with the oven, you will be able to adjust these
factors.
It is better to undercook rather than overcook
foods. If food is undercooked, it can always be
returned to the oven for further cooking. If food is
overcooked, nothing can be done. Always start
with minimum cooking times.
Important.
If the recommended cooking times are exceeded
the food will be spoiled and in extreme
circumstances could catch fire and possibly
damage the interior of the oven.
1. Small quantities of food.
Take care when heating small quantities of
food as these can easily burn, dry out or
catch fire if cooked too long. Always set short
cooking times and check the food frequently.
NEVER OPERATE THE OVEN WITHOUT
FOOD INSIDE.
2. Foods low in moisture.
Take care when heating foods low in
moisture, eg bread items, chocolate, popcorn,
biscuits and pastries. These can easily burn,
dry out or catch on fire if cooked too long.
We do not recommend heating foods low in
moisture such as popcorn or poppadoms.
This oven has been developed for food use.
We do not recommend that it is used for
heating non food items such as wheat bags or
hot water bottles
3. Christmas Pudding.
Christmas puddings and other foods high in
fats or sugar, eg. jam, mince pies, must not
be over heated. These foods must never be
left unattended as with over cooking these
foods can ignite. See pages 23-24.
4. Boiled Eggs.
Eggs in their shell and whole hard-boiled
eggs should not be heated in microwave
ovens since they may explode even after
microwave heating has ended.
5. Foods with Skins.
Potatoes, apples, egg yolk, whole vegetables
and sausages are examples of food with non
porous skins. These must be pierced using a
fork before cooking to prevent bursting.
6. Liquids.
Liquids and other foods must not be heated in
sealed containers since they are liable to
explode. When heating liquids, eg soup,
sauces and beverages in your microwave
oven, overheating the liquid beyond boiling
point can occur without evidence of bubbling.
This could result in a sudden boil over of the
hot liquid. To prevent this possibility the
following steps should be taken:
a) Avoid using straight-sided containers with
narrow necks.
b) Do not overheat.
c) Stir the liquid before placing the container
in the oven and again halfway through the
heating time.
d) After heating, allow to stand in the oven
for a short time, stirring again before
carefully removing the container.
e) Microwave heating of beverages can
result in delayed eruptive boiling,
therefore care should be taken when
handling the container.
7. Lids.
Always remove the lids of jars and containers
and takeaway food containers before you
microwave them. If you donʼt then steam and
pressure might build up inside and cause an
explosion even after the microwave cooking
has stopped.
8. Deep Fat Frying.
Do not attempt to deep fat fry in your oven.
Important Information – Read Carefully
En-5
English
9. Meat Thermometer.
Use a meat thermometer to check the
degree of cooking of joints and poultry only
when meat has been removed from the
microwave. If undercooked, return to the
oven and cook for a few more minutes at
the recommended power level. Do not
leave a conventional meat thermometer in
the oven when microwaving.
10. Paper, Plastic.
When heating food in plastic or paper
containers, keep an eye on the oven due to
the possibility of ignition. Do not use wire
twist-ties with roasting bags as arcing will
occur.
Do not use re-cycled paper products, eg
Kitchen roll unless they say they are
specifically designed for use in a microwave
oven. These products contain impurities
which may cause sparks and/or fires when
used.
11. Reheating.
It is essential that reheated food is served
“piping hot”.
Remove the food from the oven and check
that it is “piping hot”, ie steam is being
emitted from all parts and any sauce is
bubbling. (If you wish you may choose to
check the food has reached 72˚C with a
food thermometer – but remember do not
use this thermometer inside the
microwave.)
For foods that cannot be stirred, eg
lasagne, shepherds pie, the centre should
be cut with a knife to test it is well heated
through. Even if a manufacturerʼs packet
instructions have been followed always
check the food is piping hot before serving
and if in doubt return your food to the oven
for further heating.
12. Standing Time.
Standing time refers to the period at the end
of cooking or reheating when food is left
before being eaten, ie. it is a rest time which
allows the heat in the food to continue to
conduct to the centre, thus eliminating cold
13. Keeping Your Oven Clean.
It is essential for the safe operation of the
oven that it is wiped out regularly. Use
warm soapy water, squeeze the cloth out
well and use to remove any grease or food
from the interior. Pay particular attention to
the door seal area and also the areas
around the microwave feed guide situated
on the right hand side of the cavity wall. The
oven should be unplugged when cleaning.
14. Utensils.
Before use check that utensils/containers
are suitable for use in microwave ovens.
See pages 12-13.
15. Babies Bottles and Food Jars.
When reheating babies bottles always
remove top and teat. Liquid at the top of the
bottle will be much hotter than that at the
bottom and must be shaken thoroughly
before checking the temperature. The lid
must also be removed from babies food
jars, the contents must also be stirred or
shaken before the temperature is checked.
This should be carried out before
consumption to avoid burns. See page 23.
16. Arcing.
Arcing may occur if a metal container has
been used accidentally or if the incorrect
weight of food is used. Arcing is when blue
flashes of light are seen in the microwave
oven. If this occurs, stop the machine
immediately. If the oven is left unattended
and this continues it can damage the
machine.
17. Maximum Weight on Turntable
The maximum weight that can be placed on
the turntable is 3 Kg (6 lb 10 oz) (this
includes total weight of food and dish).

spots. See page 10 and 19.
Microwave energy has been used in this country to cook and
reheat food since early experiments with radar in World War
II. Microwaves are present in the atmosphere all the time,
both naturally and from manmade sources.
Manmade sources include radar, radio, television,
telecommunication links and car phones.
Microwaving Principles
The microwaves cause the water molecules to vibrate which
causes FRICTION, ie. HEAT. This heat then cooks the food.
Microwaves are also attracted to fat and sugar particles, and
foods high in these will cook more quickly. Microwaves can
only penetrate to a depth of 11⁄2 -2 inches (4-5 cm) and as heat
spreads through the food by conduction, just as in a traditional
oven, the food cooks from the outside inwards.
In a microwave oven,
electricity is converted
into microwaves by the
MAGNETRON
REFLECTION
The microwaves bounce
off the metal walls
and the metal door
screen.
TRANSMISSION
Then they pass through
the cooking containers
to be absorbed by the
water molecules in the
food, all foods contain
water to a more or
lesser extent.
How Microwaves cook food
The dish used to cook or
reheat the food will get warm
during cooking, as the heat
conducts from the food. Even
in micro waving, oven gloves
are required!
MICROWAVES CANNOT
PASS THROUGH METAL
AND THERE FORE METAL
COOKING UTEN SILS CAN
NEVER BE USED IN A
MICROWAVE, FOR
COOKING ON MICROWAVE
ONLY
This is because these foods
rely on dry external heat to
cook correctly, do not attempt
to cook by micro wave.
Foods that require deep fat
frying cannot be cooked
either.
STANDING TIME
When a microwave oven is
switched off, the food will
continue to cook by
conduction – NOT BY
MICROWAVE ENERGY.
Hence STANDING TIME is
very important in microwaving,
particularly for dense foods
i.e. meat, cakes and reheated
Boiled Eggs
Do not boil eggs in your
microwave. Raw eggs boiled
in their shells can explode
and cause serious injury.

1. Do not operate the oven without the Roller
Ring and Glass Turntable in place.
2. Only use the Glass Turntable specifically
designed for this oven. Do not substitute
with any other Glass Turntable.
3. If Glass Turntable is hot, allow to cool before
cleaning or placing in water.
4. Do not cook directly on Glass Turntable.
Always place food in a microwave safe dish.
The only exception to this is when cooking
Jacket Potatoes or Auto Program Jacket
Potatoes.
5. If food or utensils on the glass turntable
touch the oven walls this will cause the
turntable to stop moving. It will then
automatically rotate in the opposite direction.
This is normal. Open oven door, reposition
the food and restart.
6. The Glass Turntable can rotate in either
direction. The maximum weight that can be
placed on the turntable is 3 Kg (6 lb 10 oz)
(this includes total weight of food and dish).
7. While cooking by MICROWAVE the turntable
may vibrate. This will not affect cooking
performance.
8. Arcing may occur if the incorrect weight of
food is used or a metal container has been
used accidentally. If this occurs, stop the
machine immediately.

General Guidelines
STANDING TIME
Dense foods e.g. meat, jacket potatoes and
cakes, require standing time (inside or outside
of the oven) after cook ing, to allow heat to finish
con ducting to cook the centre completely. Wrap
meat joints and jacket potatoes in aluminium
foil while standing. Meat joints need approx. 1015 minutes, jacket potatoes 5 minutes. Other
foods such as plated meals, vegetables, fish
etc require 2-5 minutes standing. If food is not
cooked after standing time, return to the oven
and cook for additional time. After defrosting
food, standing time should also be allowed. See
pages 18-20.
Small quantities cook faster than large
quantities, also small meals will reheat more
quickly than large portions.
Foods cook more quickly and evenly if spaced
apart. NEVER pile foods on top of each other.
MOISTURE CONTENT
Many fresh foods e.g. veget ables and fruit, vary
in their moisture content throughout the season,
particularly jacket potatoes. For this reason
cooking times may have to be adjusted. Dry
ingredients e.g. rice, pasta, can dry out during
storage so cooking times may differ.
DENSITY
Porous airy foods heat more quickly than dense
heavy foods.
CLING FILM
Cling film helps keep the food moist and the
trapped steam assists in speeding up cooking
times. Pierce before cooking to allow excess
steam to escape. Always take care when
removing cling film from a dish as the build-up
of steam will be very hot.
The skin or membrane on some foods will
cause steam to build up during cooking. These
foods must be pierced or a strip of skin should
be peeled off before cooking to allow the steam
to es cape. Eggs, potatoes, apples, sausages
etc, will all need to be pierced before cooking.
DO NOT ATTEMPT TO BOIL EGGS IN THEIR
SHELLS.
Cover foods with microwave cling film or a lid.
Cover fish, vegetables, cas seroles, soups. Do
not cover cakes, sauces, jacket potatoes or
pastry items.

General Guidelines
SHAPE
Even shapes cook evenly. Food cooks better
by microwave when in a round container rather
than square.
STARTING TEMPERATURE
The colder the food, the longer it takes to heat
up. Food from a fridge takes longer to reheat
than food at room temperature. Food
temperature should be between 5 and 8°C
before cooking.
LIQUIDS
All liquids must be stirred before, during and
after heating. Water espe cially must be stirred
before and during heating, to avoid eruption.
Do not heat liquids that have previously been
boiled. DO NOT OVERHEAT.
TURNING AND STIRRING
Some foods require stirring during cooking.
Meat and poultry should be turned after half the
cooking time.
ARRANGING
Individual foods e.g. chicken portions or chops,
should be placed on a dish so that the thicker
parts are towards the outside.
CHECKING FOOD
It is essential that food is checked during and
after a recommended cooking time, even if an
AUTO PROGRAM has been used (just as you
would check food cooked in a conven tional
oven). Return the food to the oven for further
cooking if necessary.
DISH SIZE
Follow the dish sizes given in the recipes, as
these affect the cook ing and reheating times. A
quan tity of food spread in a bigger dish cooks
and reheats more quickly.
CLEANING
As microwaves work on food particles, keep
your oven clean at all times. Stubborn spots of
food can be removed by using a branded
microwave spray cleaner, sprayed onto a soft
cloth. Always wipe the oven dry after cleaning.
En-11
English
When unsure that a cooking
con tainer is suitable for use in
your microwave, check by the
follow ing test:
1. Fill a microwave safe
measur ing jug with 300ml
(
1
⁄
2
pt) cold water.
2. Place it on the turntable
along side the dish to be
tested. If the dish you are
testing is a large dish, then
stand the measur ing jug on
top of the empty dish.
3. Heat on HIGH power for
1 minute.
Result
If the dish is suitable for micro waving, it will remain cool,
whilst the water in the jug will
begin to feel warm. If the
testing dish feels warm, do not
use as it is obvious ly
absorbing microwave energy.
N.B. This test does not apply
to plastic or metal based
con tainers e.g. Le Creuset
®
style dishes, which should not
be used as they are cast iron
covered with enamel.
Containers to use
OVEN GLASS
Glass that is heat
resistant e.g. Pyrex®,
is ideal.
Do not use delicate
glass which may crack
due to the heat from
the food. Do not use
lead crystal which may
crack or arc.
CHINA AND CERAMIC
Glazed china plates,
saucers, bowls, mugs
and cups can be used
if they are heat
resistant. Porcelain
and ceramic are also
ideal. Fine bone china
should only be used
for reheating for short
periods, otherwise the change in tempera ture
may crack the dish or craze the finish. Do not
use dishes with a metal rim or pattern. Do not
use jugs or mugs with glued handles, since the
glue can melt in a microwave.
POTTERY, EARTHENWARE,
STONEWARE
Only use if completely
glazed. Do not use if
partially glazed or
unglazed, as they are
able to absorb water
which will absorb
microwave energy,
making the container
very hot and slowing
food.
FOIL/METAL CONTAINERS
NEVER ATTEMPT TO
COOK IN FOIL OR
METAL con tai ners –
the microwaves cannot
pass through and the
food will not heat
evenly – this may also
damage your oven.
Use wooden kebab
sticks instead of metal skewers.
Quick Check Guide to Cooking Utensils
Choosing the correct container is a very important factor in deciding the success or failure of your
cooking.
Testing Dishes for Suitability
En-12
PLASTIC
Many plastic containers are designed for
microwave use. Only use Tupperware
®
containers if they are designed for microwave
use. Do not use Melamine as it will scorch. Do
not use plastic for cooking foods high in sugar or
fat or foods that require long cooking times e.g.
brown rice. Never cook in margarine containers
or yogurt pots, as these will melt with the heat
from the food.
PAPER
Plain white kitchen paper (kitchen towel) can
be used for covering blind pastry cases and for
cover ing bacon to prevent splattering ONLY
USE FOR SHORT COOKING TIMES. NEVER
RE-USE A PIECE OF KITCHEN TOWEL. Avoid
kitchen paper containing manmade fibres.
Check that branded re-cycled kitchen towel is
recommended for microwave use. Do not use
waxed or plastic coated cups as the finish may
melt in the oven. Greaseproof paper can be
used to line the base of dishes and to cover
fatty foods. White paper plates can be used for
SHORT RE HEATING TIMES.
WICKER, WOOD, STRAW BASKETS
Do not use these items in your microwave.
With continued use and with prolonged
exposure they will crack and could ignite. Do
not use wooden dishes in your microwave.
CLING FILM
Use microwave cling film to cover food that is
to be reheated, or cooked, taking care to avoid
the film being in direct contact with the food.
ALUMINIUM FOIL
Small amounts of smooth aluminium foil can be
used to SHIELD joints of meat during
defrosting and cooking. As the microwaves
cannot pass through the foil this prevents the
shielded parts from overcooking or
overdefrosting. The foil must not touch the
sides or roof of the oven, as this may cause
arching and damage your oven.
ROASTING BAGS
These are useful when slit up one side to tent a
joint of meat when roasting by power and time.
Do not use the metal twists supplied.

Bread
This program is suitable for small items which are required for immediate use, they may feel warm
straight after defrosting. Loaves can also be defrosted on this program but these will require
standing time to allow the centre to thaw out. Standing time can be shortened if slices are
separated and buns and loaves cut in half. Items should be turned halfway during defrosting. THIS
PROGRAM IS NOT SUITABLE FOR CREAM CAKES OR DESSERTS e.g. cheesecake. See
Meat Items (mince/chops/chicken portions)
It is necessary for mince to be broken up frequently during defrosting and this is best carried out in
a large shallow dish.
THIS PROGRAM IS NOT SUITABLE FOR SAUSAGES, these can be defrosted manually using
Defrost power and time. Chops and chicken portions should be arranged in a single layer and
Meat Joints / Whole Chickens
Whole chickens and meat joints will require shielding during defrosting especially if it is a
particularly fatty piece. This is to prevent food starting to cook on the outside edges. Protect wings,
breast and fat with smooth pieces of aluminium foil secured with cocktail sticks. DO NOT ALLOW
THE FOIL TO TOUCH THE WALLS OF THE OVEN. Standing time of at least 1 hour should be
allowed for joints after defrosting

Defrosting Guidelines
Arrange food in a single layer.
Shield chickens and joints of
meat .
Turn or break up food as soon
as possible.
For Best Results:
1. Place foods in a suitable container. Meat joints and chickens should be placed on an upturned
saucer or on a plastic rack if you have one.
2. Check food during defrosting, as foods vary in their defrosting speed.
3. It is not necessary to cover the food.
4. Always turn or stir the food especially when the oven “beepsʼʼ. Shield if necessary (see point 6).
5. Minced meat, chops and other small items should be broken up or separated as soon as
possible and placed in a single layer.
6. Shielding prevents food cooking. It is essential when defrosting chickens and joints of meat.
The outside thaws out first, so protect wings/breast and fat with smooth pieces of aluminium foil
secured with cocktail sticks.
7. Allow standing time so that the centre of the food thaws out. (Minimum of 1 hour for joints of
meat and whole chickens).

the Microwave power level then the cooking time automatically. Select the category of food and
then just enter the weight. The weight is entered in grams.
The Auto Weight Programs are designed to take the guesswork out of reheating or cooking your
food. They must ONLY be used for the foods described and within the weight range
recommended. To allow for some variations that occur in food, check that food is thoroughly
cooked and piping hot before serving.

Cooking and Reheating Guidelines
Most foods reheat very quickly in your oven by HIGH power.
Meals can be brought back to serving temperature in just
minutes and will taste freshly cooked and NOT leftover.
Always check food is piping hot and return to oven if
necessary.
As a general rule, always cover wet foods, e.g. soups,
casseroles and plated meals.
Do not cover dry foods e.g. bread rolls, mince pies, sausage
rolls etc.
The charts on pages 2 -2 show you the best way to cook
or reheat your favourite foods. The best method depends on
the type of food.
Remember when cooking or reheating any food that it
should be stirred or turned wherever possible. This ensures
even cooking or reheating on the outside and in the centre.
When is food reheated?
Food that has been reheated or cooked should be served
“piping hot” i.e. steam should be visibly emitted from all
parts. As long as good hygiene practices have been followed
during the prepa ra tion and storage of the food, then cooking
or reheating presents no safety risks.
Foods that cannot be stirred should be cut with a knife to
test that they are adequately heated throughout. Even if a
manufac tur erʼs instructions or the times in the cookbook
have been followed, it is still important to check the food is
heated thoroughly. If in doubt, always return to the oven for
further reheating.
If you cannot find the equivalent food in the chart then
choose a similar type and size listed and adjust the cooking
time if necessary.
PLATED MEALS
Everyoneʼs appetite varies
and reheat times depend on
meal contents. Dense items
e.g. mashed potato, should
be spread out well. If a lot of
gravy is added, extra time
may be required. Place
denser items to the outside
of the plate. Between 4-7
mins. on HIGH power will
reheat an average portion
Do not stack meals.
CANNED FOODS
Remove foods from can and
place in a suitable dish
before heating.
SOUPS
Use a bowl and stir before
heating and at least once
through reheat time and
again at the end.
CASSEROLES
Stir halfway through and
again at the end of heating.
MINCE PIES - CAUTION
CHRISTMAS PUDDINGS
AND LIQUIDS - CAUTION
REMEMBER even if the pastry
is cold to the touch, the filling will
be piping hot and will warm the
pastry through. Take care not to
overheat otherwise burning can
occur due to the high fat and
sugar content of the filling.
Check the temperature of the
filling before consuming to avoid
burning your mouth.
BABIES BOTTLES CAUTION
Milk or formula MUST be shaken
thoroughly before heating and
again at the end and tested
carefully before feeding a baby.
For 7-8 fl.oz. of milk from fridge
temperature, remove top and
teat. Heat on HIGH power for
30-50 secs.
CHECK CAREFULLY.
For 3 fl.oz. of milk from fridge
temperature, remove top and
teat. Heat on HIGH power for
15-20 secs.
CHECK CAREFULLY
N.B. Liquid at top of bottle will
be much hotter than at bottom.
The bottle must be shaken
thoroughly and tested before
use.
WE DO NOT RECOMMEND
THAT YOU USE YOUR
MICROWAVE TO STERILISE
BABIESʼ BOTTLES. If you have
a special microwave steriliser we
urge extreme caution, due to the
low quantity of water involved. It
is vital to follow the
manufacturers instructions
implicitly.
Take great care when reheating
these items.
Do not leave unattended.
Do not add extra alcohol.
