PRECAUTIONS TO AVOID POSSIBLE EXPOSURE
TO EXCESSIVE MICROWAVE ENERGY
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
and a grounding plug. The plug must be
plugged into an outlet that is properly installed
and grounded.
w WARNING w
Improper grounding can result in a risk of electric shock. Consult a qualified electrician if the
grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded, and either:
1. If it is necessary to use an extension cord,
use only a 3-wire extension cord that has a
3-blade grounding plug, and a 3-slot receptacle that will accept the plug on the appliance.
The marked rating of the extension cord shall
be equal to or greater than the electrical
rating of the appliance, or. . . .
2. Do not use an extension cord. If the power
supply cord is too short, have a qualified
electrician or serviceman install an outlet near
the appliance.
NOTES:
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.
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
countertop or tabletop where it can be pulled
on by children or tripped over accidentally.
Ensure proper ground
exists before use

cord or shut off power at the fuse or circuit breaker panel.
d. Do not use the cavity for storage purposes. Do not leave paper products, cooking utensils, or food in
the cavity when not in use.
17. Liquids, such as water, coffee, or tea are able to be overheated beyond the boiling point without appearing to
be boiling. 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 THE CONTAINER IS DISTURBED OR A SPOON OR OTHER UTENSIL IS INSERTED INTO THE LIQUID. To reduce
the risk of injury to persons; 1) Do not overheat the liquid. 2) Stir the liquid both before and halfway through
heating it. 3) Do not use straight-sided containers with narrow necks. 4) After heating, allow the container to
stand in the microwave oven for a short time before removing the container. 5) Use extreme care when
inserting a spoon or other utensil into the container.
18. Avoid heating small-necked containers such as syrup bottles.
19. Avoid using corrosive and vapors, such as sulfide and chloride.
20. Liquids heated in certain shaped containers (especially cylindrical-shaped containers) may become overheat-
ed. The liquid may splash out with a loud noise during or after heating or when adding ingredients (instant
coffee, etc.), resulting in harm to the oven and possible injury. In all containers, for best results, stir the liquid
several times before heating. Always stir liquid several times between reheatings.

INSTALLATION
A. Circuits
For safety purposes this oven must be plugged into a
15 or 20 Amp circuit. No other electrical appliances or
lighting circuits should be on this line. If in doubt, consult a licensed electrician.
B. Voltage Warning
The voltage used at the wall receptacle must be the
same as specified on the oven name plate located on
the back or on the side of the control panel of the oven.
Use of a higher voltage is dangerous and may result in
a fire or other type of accident causing oven damage.
Low voltage will cause slow cooking. In case your
microwave oven does not perform normally in spite of
proper voltage, remove and reinsert the plug.
C. Placement of the Oven
Your microwave oven can be placed easily in your
kitchen, family room, or anywhere else in your home.
Place the oven on a flat surface such as a kitchen
countertop or a specially designed microwave oven
cart. Do not place oven above a gas or electric range.
Free air flow around the oven is important. Allow at
least 4 inches of space at the top, sides, and back of
the oven for proper ventilation.
D. Do not block the air vents
All air vents should be kept clear during cooking. If air
vents are covered during oven operation the oven may
overheat. In this case, a sensitive thermal safety device
automatically turns the oven off. The oven will be
inoperable until it has cooled sufficiently.
E. Radio interference
1. Microwave oven operation may interfere with TV or
radio reception.
2. When there is interference, it may be reduced or
eliminated by taking the following measures:
a. Clean the door and the sealing surfaces of the
oven.
b. Reorient the receiving antenna of radio or
television.
c. Relocate the microwave oven in relation to the TV
or radio.
d. Move the microwave oven away from the
receiver.
e. Plug the microwave oven into a different outlet
so that microwave oven and receiver are on
different branch circuits.

USE
Ovenproof Glass
• Glass treated for use in high-intensity heat
includes utility dishes, bread dishes, pie plates,
cake plates, liquid measuring cups, casseroles,
and bowls without metallic trim.
China
• Bowls, cups, serving plates, and platters without
metallic trim can be used in your oven.
Plastic
• When using plastic wrap as a cover, make sure
that the dish is deep enough so the plastic wrap
does not touch the food. As the food heats, it may
melt the plastic wrap wherever the wrap touches
the food.
• Place plastic wrap loosely over the top of the dish
and secure it by pressing the wrap to the sides of
the dish.
• Vent by turning back one corner of the plastic wrap.
This will allow excess steam to escape.
• Use plastic dishes, cups, semi-rigid freezer
containers, and plastic bags only for short time
cooking. Use these with care because the
plastic may soften from the heat of the food.
Paper
• Microwave-safe paper towels, waxed paper, paper
napkins, and paper plates with no metallic trim or
design can be used in your oven.
• Refer to the manufacturer’s label for use of any
paper product in the microwave oven.
DO NOT USE
Metal Utensil
• Metal shields food from microwave energy and
produces uneven cooking. Avoid metal skewers,
thermometers, or foil trays.
• Metal utensils can cause arcing, which is a
discharge of electric current. Arcing can damage
your microwave oven.
Metal Decoration
• Do not use metal-trimmed or metal-banded
dinnerware, casserole dishes, etc.
Centura™ Tableware
• The Corning Company recommends that you
do not use Centura tableware and some
Corelle™ closed-handle cups for microwave
cooking.
Aluminum Foil
• Avoid large sheets of aluminum foil because
they hinder cooking and may cause arcing.
• Use small pieces of foil to shield poultry legs
and wings.
• Keep all aluminum foil at least 1 inch from the
walls and door of the oven.
Wood
• Wooden bowls, boards, and baskets will dry out
and may split or crack when you use them in the
microwave oven.
Tightly Closed Containers
• Tightly closed cookware can explode. Be sure
to leave an opening for steam to escape from
covered cookware.
Brown Paper
• Avoid using brown paper bags. They absorb
heat and could burn.
Metal Twist Ties
• Always remove metal twist ties as they can
become hot and cause a fire.
