GROUNDING INSTRUCTIONS

This appliance must be grounded. In the
event of an electrical short circuit,
grounding reduces risk of electric shock by
providing an escape wire for the electric
current. The 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.
WARNING: Improper use of the grounding
plug can result in a risk of electric shock.

Electrical Requirements

The electrical requirements are a 120 volt
60 Hz, AC only, 15 amp. It is recommended
that a separate circuit serving only the oven
be provided. The oven is equipped with a
3-prong grounding plug. It must be plugged
into a wall receptacle that is pr
installed and grounded.

Power Supply Cord

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 long cord or extension cord is used˖
a) The marked electrical rating of the

operly

cord set or extension cord should
be at least as great as the
electrical rating of the appliance.

b) The extension cord must be a

grounding-type 3-wire cord, and
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
unintentionally.

Notes:

1. If you have any questions about the
grounding
consult a qualified electrician or
service person.

2. Neither RCA nor the dealer can
accept any liability for damage to the
oven or personal injury resulting from
failure to observe the electrical
connection procedures.

Radio or TV Interference

Should there be any interference caused by
the microwave oven to your radio or TV,
check that the microwave oven is on a
different circuit, relocated the radio or TV as
far away from the oven as feasible or check
position and signal of receiving antenna.

or electrical instructions,

UTENSILS GUIDE

This section lists which utensils can be
used in the microwave, which ones have
limited use for short periods, and which
ones should not be used in the microwave.

Recommended

g Microwave browning dish ü Use to

brown the exterior of small items such as

chops, or pancakes. Follow

steaks,
the directions provided with your
browning dish.

g Microwaveable plastic wrap ü Use to

retain steam. Leave a small opening for
some steam to escape and avoid placing
it directly on the food.

g Paper towels and napkins ü Use for

short-term heating and covering; These

absorb excess moisture and prevent
spattering. Do not use recycled paper
towels, which may contain metal and
could ignite.

gGlass and glass-ceramic bowls and dishes
ü Use for heating or cooking.
g Paper plates and cups ü Use for

short-term heating at low temperatures.
Do not use recycled paper, which may
contain metal and could ignite.

gWax paper ü Use as a cover to prevent

spattering.

gThermometers ü Use only those labele

“Microwave Safe” and follow all directions.
Check the food in several places.
Conventional thermometers may be used

4

d

on microwave food once the food has
been removed from the oven.

Limited Use

Aluminum foil ü Use narrow strips of foil

g

to prevent overcooking of exposed areas.

Using too much foil can damage your

oven, so be careful.

g Ceramic, porcelain, and stoneware ü

Use these if they are labeled “Microwave
Safe”.

If they are not labeled, test them to make

sure they can be used safely.

gPlastic ü Use only if labeled “Microwave

Safe”. Other plastics can melt.

gStraw, wicker, and wood ü Use only for

short-term heating, such as warming
dinner rolls for a few seconds. Baskets
and bowls may be flammable.

Not Recommended

COOKING TECHNIQUES

gGlass jars and bottles ü Regular glass is

too thin to be used in a microwave. It can
shatter and cause damage and injury.

gPaper bags ü These are a fire hazard,

except for popcorn bags that are
designed for microwave use.

gStyrofoam plates and cups ü These can

melt and leave an unhealthy residue on
food.

gPlastic storage and food containers ü

Containers such as margarine tubs can
melt in the microwave.

gMetal utensils ü These can damage your

oven. Remove all metal before cooking.

Note: 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 becomes very hot
should not be used.

Your microwave makes cooking easier than
conventional cooking, provided you keep
these considerations in mind:

Stirring
Stir foods such as casseroles and

vegetables while cooking to distribute heat
evenly. Food at the outside of the dish
absorbs more energy and heats more
quickly, so stir from the outside to the center.
The oven will turn off when you open the
door to stir your food.

Arrangement
Arrange unevenly shaped foods, such as

chicken pieces or chops, with the thicker,
meatier parts toward the outside of the
turntable where they receive more
microwave energy. To prevent overcooking,
place delicate areas, such as asparagus
tips, toward the center of the turntable.

Shielding

Shield food with narrow strips of aluminum
foil to prevent overcooking. Areas that need
shielding include poultry wing-tips, the ends
of poultry legs, and corners of square
baking dishes. Use only small amounts of
aluminum foil. Larger amounts can damage

your oven.
Turning
Turn foods over midway through cooking to

expose all parts to microwave energy. This
is especially important with large foods such
as roasts.

Standing

Foods cooked in the microwave build up
internal heat and continue to cook for a few
minutes after heating stops. Let foods stand
to complete cooking, especially foods such
as cakes and whole vegetables. Roasts
need this time to complete cooking in the
center without overcooking the outer areas.
All liquids, such as soup or hot chocolate,
should be shaken or stirred when cooking is
complete. Let liquids stand a moment
before serving. When heating baby food,
stir well at removal and test the temperature
before serving.

Adding moisture

Microwave energy is attracted to water
molecules. Food that is uneven in moisture
content should be covered or allowed to
stand so that the heat disperses evenly.
Add a small amount of water to dry food to
help it cook.

5

BEFORE YOU CALL FOR SERVICE

If the oven fails to operate:
A) Check to ensure that the oven is plugged

in securely. If it is not, remove the plug
from the outlet, wait 10 seconds and
plug it in again securely.

B) Check for a blown circuit fuse or a

tripped main circuit breaker. If these
seem to be operating properly, test the

outlet with another appliance.
IF NONE OF THE ABOVE RECTIFIES THE SITUATION, THEN CONTACT A QUALIFIED
TECHNICIAN. DO NOT TRY TO ADJUST OR REPAIR THE OVEN YOURSELF.

C) Check to ensure that the control panel is

programmed correctly and the timer is
set.

D) Check to ensure that the door is securely

closed engaging the door safety lock
system. Otherwise, the microwave
energy will not flow into the oven.
