2. Read carefully and follow the specic “Precautions to avoid possible
exposure to excessive microwave energy” on page 4.
3. This appliance must be grounded. Connect only to properly
grounded outlet. See “GROUNDING INSTRUCTIONS” on page 7.
4. Install or position this appliance only in accordance with the
provided installation instructions on page 10.
5. Some products such as whole eggs and sealed containers -for
example, closed glass jars- can potentially explode and should not
be heated in this oven.
6. Use this appliance only for the intended uses as described in this
manual. This type of oven is specically designed to heat, cook, or
dry food. It is not designed for industrial or laboratory use. Do not
use corrosive chemicals or vapors in this appliance.
7. As with any appliance, close supervision is necessary when used by
children.
8. To reduce the risk of re in the oven cavity;
• Do not overcook food. Carefully attend the appliance when paper,
plastic, or other combustible materials are placed inside the oven to
facilitate cooking.
• Remove wire twist-ties from paper or plastic bags before placing
bag in oven.
• If materials inside the oven ignite, keep oven door closed, turn oven
off, and disconnect the power cord or shut off power at the fuse or
circuit breaker panel.
• Do not use the cavity for storage purpose. Do not leave paper
products, cooking utensils or food inside the cavity when not in use.
9. Liquids, such as water, coffee, or tea can be overheated beyond
the boiling point without appearing to be boiling due to surface
tension of the liquid. Visible bubbling or boiling when the container is
removed from the microwave oven is not always present. This could
result in very hot liquids suddenly boiling over when a spoon or
other utensil is inserted into the liquid.
10. Do not heat oil or fat for deep-frying. It is difcult to control the
temperature of oil in a microwave oven.
11. Foods with heavy skins such as potatoes, whole squash, apples and
chestnuts should be pierced with a fork or the tip of a sharp knife
before cooking.

1) The grounding instructions are not completely understood.
2) You are unsure that the appliance is properly grounded.
3) You have any questions about the grounding or electrical instructions.
POWER SUPPLY CORD
1. A short power supply cord is provided to reduce the risk of becoming entangled in
or tripping over a longer cord.
2. If the power supply cord is too short, do not use an extension cord. Have a
qualied electrician or serviceman to install an outlet near the appliance.
3. If it is absolutely necessary to use longer cord sets or an extension cord, extreme
care must be exercised.
a) Use only a grounding type 3-wire extension cord that has a 3-blade grounding
plug and a 3-slot receptacle that will accept the plug on the appliance.
b) The marked electrical rating of the cord set or extension cord must equal to
or greater than the electrical rating of the appliance. The longer cord should be
arranged so that it will not drape over the counter top or table top where it can
be pulled on by children or tripped over unintentionally.

Page 16
STIRRING
Stir foods such as casseroles and vegetables
while cooking to distribute heat evenly. Food
at the outside of the dish absorbs more energy
and heats more quickly, so stir from the
outside to the center. The oven will turn off
when you open the door to stir your food.
ARRANGEMENT
Arrange unevenly shaped foods, such as
chicken pieces or chops, with the thicker,
meatier parts toward the outside of the
turntable where they receive more microwave
energy. To prevent overcooking, place delicate
areas, such as asparagus tips, toward the
center of the turntable.
SHIELDING
Shield food with narrow strips of aluminium
foil to prevent overcooking. Areas that need
shielding include poultry wing-tips, the ends
of poultry legs, and corners of square baking
dishes. Use only small amounts of aluminium
foil. Larger amounts can damage your oven.
TURNING
Turn foods over midway through cooking to
expose all parts to microwave energy. This is
especially important with large foods such as
roasts.
STANDING
Foods cooked in the microwave build up
internal heat and continue to cook for a few
minutes after heating stops. Let foods stand
to complete cooking, especially foods such
as cakes and whole vegetables. Roasts need
this time to complete cooking in the center
without overcooking the outer areas. All
liquids, such as soup or hot chocolate, should
be shaken or stirred when cooking is complete.
Let liquids stand a moment before serving.
When heating baby food, stir well at removal
and test the temperature before serving.
ADDING MOISTURE
Microwave energy is attracted to water
molecules. Food that is uneven in moisture
content should be covered or allowed to stand
so that the heat disperses evenly. Add a small
amount of water to dry food to help it cook.
COOKING TECHNIQUES
SET UP & USE

Page 17
1. When cleaning surfaces of door and
oven that comes together on closing
the door, use only mild, nonabrasive
soaps, or detergents apply with a
sponge or soft cloth.
2. Turn off the oven and remove the
power plug from the wall socket
before cleaning.
3. Keep the inside of the oven clean.
When food splatters or spilled liquids
adhere to oven walls, wipe with a
damp cloth. Mild detergent may be
used if the oven gets very dirty. Avoid
the use of spray and other harsh
cleaners as they may stain, streak or
dull the door surface.
4. The outside surfaces should be
cleaned with a damp cloth. To
prevent damage to the operating
parts inside the oven, water should
not be allowed to sweep into the
ventilation openings.
5. Wipe the window on both sides with
a damp cloth to remove any spills or
spatters.
6. Do not allow the control panel to
become wet. Clean with a soft,
damp cloth. When cleaning the

is normal.
8. It is occasionally necessary to remove
the glass tray for cleaning. Wash
the tray in warm sudsy water or in a
dishwasher.
9. The roller ring and oven oor
should be cleaned regularly to avoid
excessive noise. Simply wipe the
bottom surface of the oven with
mild detergent. The roller ring may
be washed in mild sudsy water or
dishwasher. When removing the roller
ring from cavity oor for cleaning, be
sure to replace in the proper position.
10. Remove odors from your oven by
combining a cup of water with the
juice and skin of one lemon in a deep
bowl, microwave for 5 minutes. Wipe
thoroughly and dry with a soft cloth.
11. When it becomes necessary to
replace the oven light, please consult
a dealer to have it replaced.
12. Please do not dispose this appliance
into the domestic rubbish bin; it
