any damage, such
Hinges cover as misaligned or bent
door, damaged door seals and sealing surfaces, bro-
ken or loose door hinges and latches and dents inside
the cavity or on the door. If there is any damage, do not
operate the oven and contact your dealer or SHARP
AUTHORIZED SERVICER.
Choosinga LocationforYourOven
You will use the oven frequently so plan its location for
ease of use. It's wise, if possible, to have counter space
on at least one side ofthe oven. Allow at least 2 inches on
the sides, top and at the rear of the oven for air circula-
tion. Do not place or install the oven in any area where
heat and steam are generated; for example, next to or
above a conventional gas or electric range or above a
conventional wall oven. Heat and steam may damage
the electronics or the mechanical parts of the oven.
Built-in Kit
Some microwave models can be built into a cabinet
or wall - not near or above a heat source - using a
Sharp Built-in Kit. Model R-520JK uses the black Sharp
Built-in Kit RK-51 K27 (27") or RK-51K30 (30"). Model
R-520JW uses the white kit KR-51W27 (27") or
RK-51W30 (30"). The R-428JK uses the black Sharp
Built-in Kit RK-46K24; the R-428JW uses the white
kit RK-46W24. There is no built-in kit for the R-520KS.
If your dealer does not stock the kit, it can be ordered
directly from the SharpAccessories and Supplies Center.
Have your credit card number available and call
toll-free: t-800-642-2122 for ordering the kit to be sent
to your address.
The kit includes ducts, finish trim strips and easy-to-
follow instructions for installation as well as the location
of the power supply.
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a grounding plug.
It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National
Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces risk
of electric shock by providing an escape wire for the electric current.
WARNING - Improper use of the grounding plug can result in a risk of electric shock.

ABOUT YOUR OVEN
This Operation Manual is valuable: read it carefully
and always save it for reference.
A good microwave cookbook is a valuable asset.
Check it for microwave cooking principles, techniques,
hints and recipes. See pages 19 and 20 for ordering
the Sharp Carousel Microwave Cookbook.
NEVER use the oven without the turntable and support
nor turn the turntable over so that a large dish could
be placed in the oven. The turntable will turn both
clockwise and counterclockwise.
ALWAYShave food in the oven when it is on to absorb
the microwave energy.
When using the oven at power levels below 100%, you
may hear the magnetron cycling on and off. It is normal
for the exterior of the oven to be warm to the touch
when cooking or reheating.
Condensation is a normal part of microwave cooking.
Room humidity and the moisture in food will influence
the amount of moisture that condenses in the oven.
Generally, covered foods will not cause as much con-
densation as uncovered ones. Vents on the oven back
must not be blocked.
The oven is for food preparation only. It should not be
used to dry clothes or newspapers.
Your oven is rated 1200 watts by using the IEC Test
Procedure method. In using recipes or package direc-
tions, check food a minute or two before the minimum
time and add time accordingly.

IlNFORMATION YOU NEED TO KNOW
ABOUT UTENSILS AND COVERINGS
It is not necessary to buy all new cookware. Many
pieces already in your kitchen can be used successfully
in your new microwave oven. Make sure the utensil does
not touch the interior walls during cooking.
Usetheseutensilsfor safe microwavecooking
andreheating:
•glass ceramic (Pyroceram®), such as
Corningware ®
• heat-resistant glass (Pyrex ®)
• microwave-safe plastics
• paper plates
• microwave-safe pottery, stoneware and
porcelain
• browning dish (Do not exceed recommended
preheating time. Follow manufacturer's
directions.)
Theseitemscanbe usedforshorttime reheat-
ing of foodsthathave little fator sugarin them:
• wood, straw, wicker
DO NOT USE
• metal pans and bakeware
• dishes with metallic trim
• non-heat-resistant glass
• non-microwave-safe plastics (margarine tubs)
• 'ecycled paper products
• brown paper bags
• food storage bags
• metal twist-ties
Should you wish to check if a dish is safe for
microwaving, place the empty dish in the oven and
microwave on HIGH for 30 seconds. A dish which
Thefollowingcoveringsare ideal:
• Paper towels are good for covering foods for re-
heating and absorbing fat while cooking bacon.
• Wax paper can be used for cooking and
reheating.
• Plastic wrap that is specially marked for
microwave use can be used for cooking and
reheating. DO NOT allow plastic wrap to touch
food. Vent so steam can escape.
• Lids that are microwave-safe are a good choice
because heat is kept near the food to hasten
cooking.
• Oven cooking bags are good for large meats or
foods that need tenderizing. DO NOT use metal
twist ties. Remember to slit bag so steam can
escape.
How to use aluminum foil in your microwave
oven:
• Small flat pieces of aluminum foil placed smooth-
ly on the food can be used to shield areas that
are either defrosting or cooking too quickly.
• Foil should not come closer than one inch to any
surface of the oven.
Should you have questions about utensils or coverings,
check a good microwave cookbook or follow recipe
suggestions.
ACCESSORIESThere are many microwave ac-
cessories available for purchase. Evaluate carefully
before you purchase so that they meet your needs. A
microwave-safe thermometer will assist you in deter-
mining correct doneness and assure you that foods
have been cooked to safe temperatures. Sharp is not
responsible for any damage to the oven when acces-
sories are used.
becomes very hot should not be used.
ABOUT CHILDREN AND THE MICROWAVE
Children below the age of 7 should use the microwave
oven with a supervising person very near to them.
Between the ages of 7 and 12, the supervising person
should be in the same room.
The child must be able to reach the oven comfortably;
if not, he/she should stand on a sturdy stool.
At no time should anyone be allowed to lean or swing
on the oven door.
Children should be taught all safety precautions: use
potholders, remove coverings carefully, pay special
attention to packages that crisp food because they
may be extra hot.
Don't assume that because a child has mastered one
cooking skill he/she can cook everything.
Children need to learn that the microwave oven is not
a toy. See page 17 for Child Lock feature.

|INFORMATION YOU NEED TO KNOW
ABOUT MICROWAVE COOKING
•Arrange food carefully. Place thickest areas towards
outside of dish.
• Watch cooking time. Cook for the shortest amount
of time indicated and add more as needed. Food
severely overcooked can smoke or ignite.
• Cover foods while cooking. Check recipe or cook-
book for suggestions: paper towels, wax paper,
microwave plastic wrap or a lid. Covers prevent
spattering and help foods to cook evenly.
• Shield with small flat pieces of aluminum foil any
thin areas of meat or poultry to prevent overcooking
before dense, thick areas are cooked thoroughly.
• Stir foods from outside to center of dish once or twice
during cooking, if possible.
• Turn foods over once during microwaving to
speed cooking of such foods as chicken and ham-
burgers. Large items like roasts must be turned over
at least once.
Rearrange foods such as meatballs halfway
through cooking both from top to bottom and from
the center of the dish to the outside.
Add standing time. Remove food from oven and
stir, if possible. Cover for standing time which allows
the food to finish cooking without overcooking.
Check for doneness. Look for signs indicating that
cooking temperatures have been reached.
Doneness signs include:
- Food steams throughout, not just at edge.
- Center bottom of dish is very hot to the touch.
- Poultry thigh joints move easily.
- Meat and poultry show no pinkness.
- Fish is opaque and flakes easily with a fork.
ABOUT SAFETY
• Check foods to see that they are cooked to
the United States Department of Agriculture's
recommended temperatures.
II |k'Jl'J EI([J|I]
160°F ... forfresh pork, ground meat. bone-
less white poultry, fish. seafood.
egg dishes and frozen prepared
food.

frigerated, and dell and carry-out
"fresh" food.
170°F ... white meat of poultry.
180°F ... dark meat of poultry.
To test for doneness, insert a meat thermometer in
a thick or dense area away from fat or bone. NEVER
leave the thermometer in the food during cooking, un-
less it is approved for microwave oven use.
• ALWAYS use potholders to prevent burns when
handling utensils that are in contact with hot food.
Enough heat from the food can transfer through
utensils to cause skin burns.
• Avoid steam burns by directing steam away from
the face and hands. Slowly lift the farthest edge of
a dish's covering and carefully open popcorn and
oven cooking bags away from the face.
• Stay near the oven while it's in use and check cooking
progress frequently so that there is no chance of
overcooking food.
• NEVER use the cavity for storing cookbooks or
other items.
• Select, store and handle food carefully to preserve
its high quality and minimize the spread of foodborne
bacteria.
• Keep waveguide cover clean. Food residue can
cause arcing and/or fires.
• Use care when removing items from the oven so
that the utensil, your clothes or accessories do not
touch the safety door latches.
