18. Liquids, such as water, coffee, or tea are able to be overheated beyond the
boiling point without appearing to be boiling. Visible bubbling when the con-
tainer is removed from the microwave oven is not always present. THIS
COULD RESULT IN VERY HOT LIQUIDS SUDDENLY BOILING OVER
WHEN THE CONTAINER IS DISTURBED OR A UTENSIL IS INSERTED
INTO THE LIQUID.
To reduce the risk of injury to persons:
(a) STIR THE LIQUID BOTH BEFORE AND HALFWAY THROUGH
HEATING IT.
(b) Do not heat water and oil, or fats together. The film of oil will trap

—IMPROPER USE OF THE GROUNDING PLUG
CAN RESULT IN A RISK OF ELECTRIC SHOCK. 
Consult a qualified electrician or service person if the grounding instructions are not com-
pletely understood, or if doubt exists as to whether the appliance is properly grounded. If it
is necessary to use an extension cord, use only a three wire extension cord that has a
three prong polarized grounding plug, and a three slot receptacle that will accept the plug
on the appliance. The marked rating of the extension cord should be equal to or greater
than the electrical rating of the appliance.
Grounding Instructions
THIS APPLIANCE MUST BE GROUNDED.In the event of an electrical short circuit,
grounding reduces the risk of electric shock by providing an escape wire for the electric
current. This appliance is equipped with a cord having a grounding wire with a grounding
plug. The plug must be plugged into an outlet that is properly installed and grounded.
• Plug into properly installed and grounded 3 prong outlet.
• DO NOT remove ground prong.
• DO NOT use an adapter.
Power Supply
1. A short power-supply cord is provided to reduce the risks resulting from becoming
entangled in or tripping over a longer cord.
2. Longer cord sets or extension cords are available and may be used if care is exercised
in their use. Do notlet cord hang over edge of a table or counter.
3. If a long cord or extension cord is used, (1) the marked electrical rating of the cord set
or extension cord should be at least as great as the electrical rating of the appliance, (2)
the extension cord must be a grounding-type 3-wire cord, and (3) 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 accidentally.
Wiring Requirements
The oven must be operated on a SEPARATE CIRCUIT. No other appliance should share
the circuit with the microwave oven. If it does, the branch circuit fuse may blow or the cir-
cuit breaker may trip. The oven must be plugged into at least a 15 AMP, 120 VOLT, 60 Hz
GROUNDED OUTLET. Where a standard two-prong outlet is encountered, it is the
personal responsibility and obligation of the consumer to have it replaced with a properly
grounded three-prong outlet. The VOLTAGE used must be the same as specified on this
microwave oven (120 V, 60 Hz). Using a higher voltage is dangerous and may result in a
fire or oven damage. Using a lower voltage will cause slow cooking. Panasonic is NOT
responsible for any damages resulting from the use of the oven with any voltage other
than specified.
TV / Radio Interference
1. Operation of the microwave oven may cause interference to your radio, TV or similar
equipment.
2. When there is interference, it may be reduced or eliminated by taking the following
measures:
(a) Place the radio, TV, etc. away from the microwave oven as far as possible.   
(b) Use a properly installed antenna to obtain stronger signal reception.
(c) Clean door and sealing surfaces of the oven. (See Care and Cleaning of Your

Follow These Safety Precautions When Cooking in Your Oven.
IMPORT
ANT
Proper cooking depends upon the power, the time setting and quantity of
food. If you use a smaller portion than recommended but cook at the time
for the recommended portion, fire could result. 
1) HOME CANNING / STERILIZING / DRYING FOODS /
SMALL QUANTITIES OF FOODS
• DO NOTuse your oven for home canning. Your oven cannot maintain the food
at the proper canning temperature. The food may be contaminated and then
spoil.
• DO NOTuse the microwave oven to sterilize objects (baby bottles, etc.). It is
difficult to keep the oven at the high temperature needed for sterilization.
• DO NOTdry meats, herbs, fruits or vegetables in your oven. Small quantities
of food or foods with low moisture content can dry out, scorch or catch on fire if
overheated.
2) POPCORN
Popcorn may be popped in a microwave oven corn popper. Microwave pop-
corn which pops in its own package is also available. Follow popcorn manu-
facturers’ directions and use a brand suitable for the cooking power of your
microwave oven. 
CAUTION:When using pre-packaged microwave popcorn, you can follow
recommended package instructions or use the popcorn pad (refer to page 12).
Otherwise, the popcorn may not pop adequately or may ignite and cause a
fire. Never leave oven unattended when popping popcorn. Allow the popcorn
bag to cool before opening, always open the bag facing away from your face
and body to prevent steam burns.
3) DEEP FAT FRYING
• DO NOTdeep fat fry in your microwave oven. Cooking oils may burst into
flames and may cause damage to the oven and perhaps result in burns.
Microwave utensils may not withstand the temperature of the hot oil, and can
shatter or melt.
4) FOODS WITH NONPOROUS SKINS
• DO NOT COOK/REHEAT WHOLE EGGS, WITH OR WITHOUT THE SHELL.
Steam buildup in whole eggs may cause them to explode, and possibly dam-
age the oven or cause injury. Reheating SLICED hard-boiled eggs and cooking
SCRAMBLED eggs is safe.
• Potatoes, apples, whole squash and sausagesare examples of foods with
nonporous skins. These types of foods must be pierced before microwave
cooking to prevent them from exploding.
CAUTION:Cooking dry or old potatoes can cause fire.
Safety Precautions
F00037E20AP  2005.03.03  14:38  Page 7

5) GLASS TRAY / COOKING CONTAINERS / FOIL
• Cooking containers get hot during microwaving. Heat is transferred from the
HOT food to the container and the Glass Tray. Use pot holders when removing
containers from the oven or when removing lids or plastic wrap covers from
cooking containers, to avoid burns.
• The Glass Tray will get hot during cooking. It should be allowed to cool before
handling or before paper products, such as paper plates or microwave popcorn
bags, are placed in the oven for microwave cooking.
• When using foil in the oven, allow at least 1-inch (2.5 cm) of space between
foil and interior oven walls or door.
• Dishes with metallic trim should notbe used, as arcing may occur.
6) PAPER TOWELS / CLOTHS
• DO NOTuse paper towels or cloths which contain a synthetic fiber woven into
them. The synthetic fiber may cause the towel to ignite. Use paper toweling
under supervision.
7) BROWNING DISHES / OVEN COOKING BAGS
• Browning dishes or grills are designed for microwave cooking only. Always fol-
low instructions provided by the manufacturer. DO NOTpreheat browning dish
more than 6 minutes.
• If an oven cooking bag is used for microwave cooking, prepare according to
package directions. DO NOTuse a wire twist-tie to close bag, instead use
plastic ties, cotton string or a strip cut from the open end of the bag.
8) THERMOMETERS
• DO NOTuse a conventional meat thermometer in your oven. Arcing may
occur.  Microwave safe thermometers are available for both meat and candy.
9) BABY FORMULA / BABY FOOD
• DO NOTheat baby formula or baby food in the microwave oven. The glass jar
or surface of the food may appear warm while the interior can be so hot as to
burn the infant’s mouth and esophagus.
10) REHEATING PASTRY PRODUCTS
• When reheating pastry products, check temperatures of any fillings before eat-
ing. Some foods have fillings which heat faster and can be extremely hot, while
the surface remains warm to the touch (ex. Jelly Donuts).
11) GENERAL OVEN USAGE GUIDELINES
• DO NOTuse the oven for any purpose other than the preparation of food.
