PRODUCT DESCRIPTION

EXPLANATION OF MICROWAVE COOKING AND CONVECTION COOKING
The Sharp Convection-Microwave oven uses microwave
energy and the sheath heater to produce heat in the food to
be cooked.
Unlike conventional ovens, microwave energy will cook
foods without applying external heat.
Microwaves which are short electromagnetic waves of RF
(radio frequency) energy, pass through materials such as
glass, paper, china, and most plastics. Materials such as
metal and aluminum foil tend to reflect microwaves and
may be used only as recommended in the cooking
instructions.

Materials with a high moisture content, like most foods,
will absorb microwave energy. As the microwave energy,
at a frequency of 2,450 Megahertz enters the food, the
molecules align themselves with the energy. However,
cooking by microwave energy only, produces no brown-
ing or searing (unless cooking a roast of sufficient thick-
ness). This microwave oven is, therefore, equipped with
a sheath heater to provide browning of the food.
The combination of the heater plus high-speed circulation
of air by a circulating fan around the food provides fast
cooking and browning of foods conventionally with or
without the addition of microwave energy.

CHAPTER I I
OPERATING INSTRUCTIONS
OPERATION OF AUTO-TOUCHTM CONTROL PANEL
This Auto-Touch Convection Microwave Oven uses a microprocessor, the electronic brain that provides
a wide variety of cooking programs which could not be achieved by conventional control methods.
The operation of the oven is controlled by touching the appropriate pads arranged on the surface of
the control panel. The lighting digital readout will display the cooking time, convection temperature,
memory or time of day, and indicators show the variable cooking setting or cooking function you have
programmed.
An audible entry signal tone should be heard each time you touch the control panel to make a correct
entry. If you do not hear this sound,
1) you have not used enough pressure in touching the pad,
2) you have made more entries than the control panel will accept,
3) you have made an incorrect entry.
In addition to the entry signal tone, an audible signal will sound for approximately 2 seconds at the
end of the cooking cycle.
The following pages give complete instructions for using the Auto-Touch control system. Please use
these instructions and practice programming the oven step by step until you are thoroughly familiar
with its operation.
In giving directions, examples of foods have been used so that you may become familiar with the
practical uses for these features. However, we suggest that
yocr first practice operating the oven with
one cup of water in a glass measuring cup inside rather than food.
Do not operate the oven empty.
*You cannot program the oven if the door is not closed tightly.
* During cooking, the program cannot be changed until the STOP pad is touched.
All functions are locked in to prevent accidental changes.
Multiple Sequence Cooking
This Auto Touch Convection Microwave Oven can be programmed for multiple cooking sequences for
microwave, convection and combination convection microwave. Some of the sequences you might use
in cooking include:

OPERATION FOR MICROWAVE COOKING
Throughout This Carousel Convection Microwave Cookbook you will find step by step directions for
each recipe. Basic instructions follow:
1. Make sure the oven is plugged into a 3-pronged, grounded 240V (Australia)/220V (South Africa),
50 Hz, 10 amp household circuit. When oven is plugged in, the display will show (61 ,flashing
on and off each second. Touch the CLEAR pad; [I will appear.
2. Always make certain the metal turntable is seated and in place. The oven should not be used with-
out the turntable in place, and it should never be restricted so that it cannot rotate.
3. The Variable Cooking Control on your Sharp Convection Microwave Oven allows you to select the
amount of microwave energy and the rate of cooking or defrosting. There are four levels or settings
for cooking: HIGH, MED HIGH, MED and MED LOW/DEFROST. Your cookbook explains the
use of this feature.
4. Be sure to select the recommended power level before beginning to cook. Refer to Operation of
Auto-Touch Control Panel for proper procedure. If you do not touch a setting on the Variable
Cooking Control panel, the oven will automatically cook at HIGH. Each recipe in your cookbook
gives instructions for the setting best suited for that particular food category. As you become more
familiar with the use of the Variable Cooking Control and microwave cooking, you will be able to
judge which power level to use for various foods.
5. If food does not seem to be heating properly, check the indicator immediately above the lighted
digital display. Be sure the Variable Cooking Control is on the proper setting.
6. The oven is programmed by touching the appropriate Auto-Touch pads.

INTRODUCTION TO CONVECTION COOKING
Convection cooking is a not-so-new form of food preparation that has been used by professional chefs
for three decades for roasting and baking. Hot air is circulated throughout the oven cavity by a high
speed fan. The constantly moving air surrounds the food to quickly heat the outer portion, thereby
sealing in moisture and natural juices. This “sealing-in” process results in more flavorful foods cooked
in less time and in many cases at a reduced temperature. The oven can be filled to capacity, using
both the turntable and the baking rack, with no increase in cooking time.
While all foods that are roasted, baked or broiled benefit from convection cooking, the added micro-
wave feature of your new oven makes it possible to cook a wide range of foods in combination - that
is with convection, then microwaves or vice-versa.
This section of the Operation Manual explains the use of the oven for Convection heating alone and
combination cooking. Please use it as a guide along with the Carousel Convection Microwave cook-
book.
ACCESSOR!ES
The following accessories were designed especially for use in the Sharp Convection Microwave Oven.
The racks are for convection or combination cooking only; do not use for microwave cooking alone.
Do not substitute similar types of racks for these specially designed ones.
Baking Rack
Broiling Trivet
- This rack is used for two-levels cooking,
- Used for roasting or broiling to allow
such as layer cakes, muffins, cookies, etc. juices to drain away from food.
CONVECTION HEATING
Some foods are best when cooked using convection heating alone. These are foods which often have
a cooking time of 15 minutes or less and usually need quick crisping and browning. These include:
Appetizers - frozen, pastry-type, or other
Biscuits and rolls - dairy case, brown n’serve, your recipe
Brownies - mix, your recipe
Biscuits -
mix, slice n’bake, frozen, your recipe
Cream puffs, puff pastry, turnovers, etc.
Fish sticks - frozen, breaded
Muffins -
mix, your recipe
Pie crust - frozen, mix, your recipe
Pizza
- fresh, frozen, or your recipe

Basic Convection Heating Procedure
1. Consult recipe or package directions for temperature and time.
2. Preheat oven if required by recipe or package directions.
3. Food may be cooked directly on turntable if appropriate, or on two levels using baking rack and
appropriate baking vessel. Example: Fish sticks may be cooked directly on turntable. Muffins may
be cooked on 2 levels using the baking rack and two &muffin baking pans.
4. Check for doneness at the end of cooking time.

/Helpful
1. Do not cover turntable or baking rack with aluminum foil. It interferes with the flow of air that
cooks food.
2. If food is not done when checked after cooking time, let stand in oven one or two minutes to
complete cooking.
3. Round pizza pans are excellent cooking utensils for many convection-only items. Choose pans that
do not have extended handles.

CONVECTION BROILING
This Convection Microwave Oven wil broil meats, fresh or frozen to perfection! As in conventional
cooking, broiling time will vary with thickness as well as weight. For best results use the directions
that follow.
Basic Convection Broiling Procedure
1. Preheat oven 10 minutes at 250°C.
2. Prepare and season meat on both sides, as desired.
3. Place meat on broiling trivet or turntable.
4. Consult broiling chart in your Sharp Carousel Convection Microwave Cookbook; set timer for
correct cooking time.
5. Turning meat over is not necessary.
6. Test for doneness; slit center of meat, check for desired color; red - rare, pink - medium, gray -
well done.
jHelpfulHints
-.
1. Do not cover broiling trivet with aluminum foil. It interferes with the flow of air that cooks food.
2. For faster clean up spray trivet and turntable with nonstick vegetable spray.
3. To eliminate excess fat in broiling, use broiling trivet.
4. Broiling may be done ahead of time, then individual portions sliced and reheated with microwave
power (MEDIUM setting) as needed.
5. Hot dogs cooked on the broiling trivet may be turned over to give an even, grilled appearance.
Recommended Broiling Utensils
Sharp recommends only the use of the metal Carousel turntable, and the broiling trivet and baking
rack accessories that are included with the oven,

MIX COOKING
With the exception of those foods that cook best by convection heating alone, most foods are well
suited to mix cooking using either the LOW MIX or HIGH MIX setting.
The marriage of convection and microwave cooking produces juicy roasts, moist and tender cakes
and fine textured breads, all with just the right amount of browning and crispness.
MIX ROASTING
Mix roasting in the Sharp Convection Microwave Oven is a simple task when you follow the instruc-
tions given below. The results are juicy, crisp browned meats done to your liking.
Basic Roasting Procedure
1. Place meat directly on the turntable or on the metal broiling trivet, or in a shallow roasting pan on
the turntable, as you prefer.
2. Season, as desired.
3. Consult chart in your Sharp Carousel Convection Microwave Cookbook for roasting temperature
and timing.
4. Program oven for appropriate cooking time and mix setting. Change temperature if recipe requires.
5. Check for desired doneness using a meat thermometer. If desired, a dual safe microwave/conven-
tional thermometer may be inserted in the meat at the beginning of cooktime.”
6. Let meat stand tented with to 15-10 minutes before slicing.
* A dual safe thermometer is specially designed to withstand high temperature and can safely be used
with heat or microwaves. Do not use conventional meat thermometers for mix cooking and do not
use microwave only thermometers for mix cooking.
1 Helpful Hints 1
1. If roasting frozen meat, insert dual safe meat thermometer halfway through cooking time.
2. Thin sections of meat, and wingtips and legs of poultry that may overcook, can be shielded with
small pieces of aluminum foil.
3. Less tender cuts of beef can be roasted and tenderized using oven cooking bags.
4. For true roasting, and fewer calories, use metal broiling trivet to hold meat out of its juices.
5. If gravy is desired, roast in glass utility dish, remove meat to carving board, then microwave gravy.

Note
During mix baking some metal baking utensils may cause arcing when they come in contact with the
turntable, oven walls or accessory racks. Arcing is a discharge of electricity that occurs when micro-
waves come in contact with metal.
If arcing occurs when using a fluted tube pan, place a heat resistant dish (Pyrex pie plate, glass pizza’
dish or dinner plate) between the pan and the turntable. If arcing occurs with other metal baking
utensils, discontinue their use for mix cooking.

OPERATION FOR CONVECTION COOKING
This oven can also be used for both Convection and Automatic Convection Microwave Cooking.
During convection heating, hot air is circulated throughout the oven cavity to brown and crisp foods
quickly and evenly.
The oven should not be used without the metal turntable in place and it should never be restricted so
that it cannot rotate. You may remove the turntable when preheating the oven or when preparing
food to be cooked directly on the turntable; cookies, for example, biscuits.
