electric shock, fire, injury to persons, or exposure to
excessive microwave energy.
• Read all the instructions before using your oven.
• Do not allow children to use this oven without
close supervision.
• Read and follow the specific PRECAUTIONS TO
AVOID POSSIBLE EXPOSURE TO
EXCESSIVE MICROWAVE ENERGY found
on page 2.
• Do not use corrosive chemicals or vapors, such as
sulfide and chloride, in this appliance. This type of
oven is specifically designed to heat, cook, or dry
food. It is not designed for industrial or laboratory use.
• Do not store this appliance outdoors. Do not use
this product near water - for example, near a kitchen
sink, in a wet basement, near a swimming pool, or
similar location.
• Do not use the cavity for storage purposes. Do not
leave paper products, cooking utensils, or food in
the cavity when not in use.
• Clean the ventilating hood frequently. Do not

Please read this owner’s manual. It will tell you how
to use all the fine features of this microwave oven.
LOCATION OF MODEL NUMBER
To request service information or replacement parts,
the service center will require the complete model
number of your microwave oven. The number is on the
oven front as shown in the illustration below.
OVEN SPECIFICATIONS
ELECTRICAL REQUIREMENTS
The oven is designed to operate on a Standard
120V/60Hz household outlet. Be sure the circuit is at
least 15A or 20A and the microwave oven is the only
appliance on the circuit. It is not designed for 50Hz or
any circuit other than a 120V/60Hz circuit.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If an electrical
short circuit occurs, grounding reduces the risk of
electric shock by providing an escape wire for the
electric current. The cord for this appliance has a
grounding wire with a grounding plug. Put the plug into
an outlet that is properly installed and grounded.
WARNING - If you use the grounding
plug improperly, you risk electric shock.
Ask a qualified electrician if you do not understand the
grounding instructions or if you wonder whether the
appliance is properly grounded.
Because this appliance fits under the cabinet, it has a
short power-supply cord. See the separate Installation
Instructions for directions on placing the cord properly.
Keep the electrical power cord dry and do not pinch or
crush it in any way.
Ensure proper ground
exists before use

MICROWAVE COOKING TIPS
Amount of food
• If you increase or decrease the amount of food you
prepare, the time it takes to cook that food will also
change. For example, if you double a recipe, add a
little more than half the original cooking time. Check
for doneness and, if necessary, add more time in
small increments.
Starting temperature of food
• The lower the temperature of the food being put into
the microwave oven, the longer it takes to cook. Food
at room temperature will be re-heated more quickly
than food at refrigerator temperature.
Composition of food
• Food with a lot of fat and sugar will be heated
faster than food containing a lot of water. Fat and
sugar will also reach a higher temperature than water
in the cooking process.
• The more dense the food, the longer it takes to heat.
Very dense food like meat takes longer to heat than
lighter, more porous food like sponge cakes.
Size and shape
• Smaller pieces of food will cook faster than larger
pieces. Also, same-shaped pieces cook more evenly
than different-shaped pieces.
• With foods that have different thicknesses, the
thinner parts will cook faster than the thicker parts.
Place the thinner parts of chicken wings and legs in
the center of the dish.
Stirring, turning foods
• Stirring and turning foods spreads heat quickly to
the center of the dish and avoids overcooking at the
outer edges of the food.
Covering food
Cover food to:
• Reduce splattering
• Shorten cooking times
• Keep food moist
Releasing pressure in foods
• Several foods (for example: baked potatoes,
sausages, egg yolks, and some fruits) are tightly
covered by a skin or membrane. Steam can build up
under the membrane during cooking, causing the food
to burst. To relieve the pressure and to prevent
bursting, pierce these foods before cooking with a
fork, cocktail pick, or toothpick.
Using standing time
• Always allow food to stand either in or out of the
oven after cooking power stops. Standing time after
defrosting and cooking allows the temperature to
evenly spread throughout the food, improving the
cooking results. For inside oven standing time, you
can program a 0power second stage of the cooking
cycle. See cooking with more than on cook cycle
cooking.
• The length of the standing time depends on how
much food you are cooking and how dense it is.
Sometimes it can be as short as the time it takes you
to remove the food from the oven and take it to the
serving table. However, with larger, denser food item,
the standing time may be as long as 10 minutes.
Arranging food
For best results, place food evenly on the plate. You
can do this in several ways:
• If you are cooking several items of the same food,
such as baked potatoes, place them in a ring pattern
for uniform cooking.
• When cooking foods of uneven shapes or
thickness, such as chicken breasts, place the
smaller or thinner area of the food towards the center
of the dish where it will be heated last.
• Layer thin slices of meat on top of each other.
• When you cook or reheat whole fish, score the
skin –this prevents cracking.
• Do not let food or a container touch the top or sides
of the oven. This will prevent possible arcing.
