using Microwave Ovens for Heating
Foodstuffs
Inspection for Damage:
A microwave oven should only be used if an inspection
confirms all of the following conditions:
1. The door fits squarely and securely and opens and
English
closes smoothly.
2. The door hinges are in good condition.
3. The metal plates of a metal seal on the door are neither
buckled nor deformed.
4. The door seals are neither covered with food nor have
large burn marks.
Precautions:
Microwave radiation from microwave ovens can cause
harmful effects if the following precautions are not taken:
1. Never tamper with or deactivate the interlocking devices
on the door.
2. Never poke an object, particularly a metal object,
through a grille or between the door and the oven while
the oven is operating.
3. Never place saucepans, unopened cans or other heavy
metal objects in the oven.
4. Do not let other metallic articles, e.g. fast food foil
containers, touch the side of the oven.
5. Clean the oven cavity, the door and the seals with water
and a mild detergent at regular intervals. Never use
any form of abrasive cleaner that may scratch or scour
surfaces around the door.
6. Always use the oven with the trays or cookware
recommended by the manufacturer.
7. Never operate the oven without a load (i.e. an absorbing
material such as food or water) in the oven cavity unless
specifically allowed in the manufacturer's literature.
8. For horizontally hinged doors, never rest heavy objects
such as food containers on the door while it is open.
9. Do not place sealed containers in the microwave
oven. Baby bottles fitted with a screw cap or a teat are
considered to be sealed containers.
10. This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person
responsible for their safety.
11. Young children should be supervised to ensure that they
do not play with the appliance.
12. It is hazardous for anyone other than a competent
person to carry out any service or repair operation that
involves the removal of a cover which gives protection
against exposure to microwave energy.
Earthing Instructions
This microwave oven must be earthed. In the event of an
electrical short circuit, earthing reduces the risk of electric
shock by providing an escape wire for the electric current.
This microwave oven is equipped with an earthing plug. The
plug must be plugged into an outlet that is properly installed
and earthed.
WARNING—Improper use of the earthing plug can result in
electric shock.
Important Instructions
WARNING—To reduce the risk of burns, electric shock,
fire, injury to persons or excessive microwave energy:
1. Read all instructions before using microwave oven.
2. Some products such as whole eggs and sealed
containers - (for example, closed glass jars and sealed baby bottles with teat) may explode and should not be
heated in microwave oven.
3. Use this microwave oven only for its intended use as
described in this manual.
4. As with any appliance, close supervision is necessary
when used by children.
5. Do not operate this microwave oven, if it is not working
properly, or if it has been damaged or dropped.
6. Do not store or use this appliance outdoors.
7. Do not immerse cord or plug in water.
8. Keep cord away from heated surfaces.
9. Do not let cord hang over edge of table or counter.
10. To reduce the risk of fire in the oven cavity:
(a) Do not overcook food. Carefully attend microwave
oven if paper, plastic, or other combustible materials
are placed inside the oven to facilitate cooking.
(b) Remove wire twist-ties from bags before placing bag
in oven.
(c) If materials inside the oven should ignite, keep oven
door closed, turn oven off at the wall switch, or shut
off power at the fuse or circuit breaker panel.
(d) Never leave microwave unattended while cooking or
reheating.
11. Do not remove outer panel from oven.
12. Appliances are not intended to be operated by means of
an external timer or separate remote-control system.
13. 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.
Circuits
Your microwave ovens should be operated on a separate
circuit from other appliances. The voltage used must be the
same as specified on this microwave oven. Failure to do
this may cause the power board fuse to blow, and/or food
to cook slower. Do not insert higher value fuse in the power
board.
Warning
(a) The door seals and door seal areas should be cleaned with a damp cloth. The appliance should be inspected for
damage to the door seals and door seal areas and if these areas are damaged the appliance should not be operated
until it has been repaired by a service technician trained by the manufacturer.
(b) It is dangerous for anyone other than a service technician trained by the manufacturer to perform repair service.
(c) If the supply cord of this appliance is damaged, it must be replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard.
(d) Before use, the user should check that whether the utensils are suitable for use in microwave ovens.
(e) Liquids or other foods must not be heated in sealed containers since they are liable to explode, at the same time it
should avoid the boiling liquids splash.
(f) Only allow children to use the oven without supervision when adequate instructions have been given so that the child is
able to use the oven in a safe way and understands the hazards of improper use.
1. In order to maintain high quality, do not operate the
oven when empty. The microwave energy will reflect
continuously throughout the oven if no food or water is
present to absorb energy. This can lead to damage to
the microwave oven including arcing within the oven
cavity.
2. If smoke is observed, press the Stop/Reset Pad or
return "TIMER/WEIGHT SELECT DIAL" back to zero,
and leave door closed. Disconnect the power cord, or
shut off power at the fuse or circuit breaker panel.
3. Do not dry clothes, newspapers or other materials in
oven. They may catch on fire.
4. Do not use recycled paper products, as they may
contain impurities which may cause sparks and/or fires
when used.
5. Do not use newspapers or paper bags for cooking.
6. Do not hit or strike control panel. Damage to controls
may occur.
7. POT HOLDERS may be needed as heat from food
is transferred to the cooking container and from the
container to the glass tray. The glass tray can be very
hot after removing the cooking container from the oven.
8. Do not store flammable materials next to, on top of, or in
the oven. It could be a fire hazard.
9. Do not cook food directly on glass tray unless indicated
in recipes. (Food should be placed in a suitable cooking
utensil.)
10. DO NOT use this oven to heat chemicals or other nonfood products. DO NOT clean this oven with any product
that is labeled as containing corrosive chemicals. The
heating of corrosive chemicals in this oven may cause
microwave radiation leaks.
11. If glass tray is hot, allow to cool before cleaning or
placing in water.
12. During cooking, some steam will condense inside and/or
on the oven door. This is normal and safe. Steam will
disappear after the oven is cool down.
Placement of Oven
1. The oven must be placed on a flat, stable surface, more
than 85 cm above the floor. For correct operation, the
oven must have sufficient air flow. Allow 15 cm of space
on the top of the oven, 10 cm at back and 10 cm on
both sides. If one side of the oven is placed flush to a
wall, the other side or top must not be blocked. Do not
remove feet.
15 cm
10 cm
10 cm
OPEN
Counter-top
(a) Do not block air vents. If they are blocked during
operation, the oven may overheat. If the oven
overheats, a thermal safety device will turn the oven
off. The oven will remain inoperable until it has
cooled.
(b) Do not place oven near a hot or damp surface such
as a gas stove, electric range or sink etc.
(c) Do not operate oven when room humidity is too
high.
2. This oven was manufactured for household use only.
3. The microwave oven shall not be placed in a cabinet.
Food
1. Do not use your oven for home canning or the heating of
any closed jar. Pressure will build up and the jar may
explode. In addition, the microwave oven cannot
maintain the food at the correct canning temperature.
Improperly canned food may spoil and be dangerous to
consume.
2. Do not attempt to deep fat fry in your microwave oven.
3. Do not boil eggs in their shell (unless otherwise stated
in cookbook). Pressure will build up and the eggs will
explode.
4. Potatoes, apples, egg yolks, whole squash and
sausages are examples of foods with nonporous skins.
This type of food must be pierced before cooking, to
prevent bursting.
5. When heating liquids, e.g. 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 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 cooking time.
(d) After heating, allow to stand in the oven for a short
time, stirring again before carefully removing the
container.
6. DO NOT USE A CONVENTIONAL MEAT
THERMOMETER IN THE MICROWAVE OVEN. To
check the degree of cooking of roasts and poultry
use a MICROWAVE THERMOMETER. Alternatively, a
conventional meat thermometer may be used after the
food is removed from the oven. If undercooked, return
meat or poultry to the oven and cook for a few more
minutes at the recommended power level. It is important
to ensure that meat and poultry are thoroughly cooked.
7. COOKING TIMES given in the cookbook are APPROXIMATE. Factors that may affect cooking time
are preferred degree of moisture content, starting
temperature, altitude, volume, size, shape of food and
utensils used. As you become familiar with the oven,
you will be able to adjust for these factors.
8. 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 recommended.
9. Extreme care should be taken when cooking popcorn
in a microwave oven. Cook for minimum time as
recommended by manufacturer. Use the directions
suitable for the wattage of your microwave oven.
NEVER leave oven unattended when popping popcorn.
10. When heating food in plastic or paper containers, check
the oven frequently due to the possibility of ignition.
11. The contents of feeding bottles and baby food jars are
to be stirred or shaken and the temperature is to be
checked before consumption, in order to avoid burns.
cooking will stop the cooking process without
cancelling the program. It is quite safe to open
the door at any time during a cooking program
and there is no risk of Microwave exposure.
For NN-ST340W model, cook resumes as
soon as the door is closed and Start Pad is
pressed.

English
Notes:
1. Turbo Defrost can be used to defrost many cuts of meat, poultry and fish by weight. To use, simply program Turbo Defrost
and the weight of the food in kg (1.0) and tenths of a kg (0.1). The oven will determine the defrosting time and power levels.
Once the oven is programmed, the defrosting time will appear in the display. For best results the minimum recommended
weight is 0.2 kg.
2. BONE-IN ROASTS, such as a Beef Rib Roast have a smaller muscle than a boneless roast of the same weight. Therefore,
for bone-in roasts weighing over 2 kg reduce weight by 0.5 kg. For bone-in roasts weighing less than 2 kg, reduce weight by
0.25 kg.
3. Turn over or remove or shield food when buzzer rings.
Pre-cooked foods are reheated automatically by setting the
food’s weight. You need not select power level or reheating
time. The foods should be at refrigerator temperature
(5-7°C). Use suitable size microwave safe bowl, add 1-4
tbsp of water, and cover with a microwave safe plastic warp.
Stir after beep sounds. After cooking, stir the food.
Note: When reheating items such as soups, stews, and
casseroles, it is recommended that they are stirred at half of
reheating time and at completion of reheating.
