WARNING:
Inspect the Oven:
• Check the oven carefully for damage
before and regularly after installation.
• Make sure the door closes properly,
that it is not misaligned or warped.
• Check the hinges and door safety
latches are not broken or loose.
• Ensure the door seal and sealing
surfaces are not damaged.
• Inspect the oven interior and door for
dents.
IMPORTANT:  
If any damage is apparent, do not
operate the oven in any way.  Contact
your dealer or  SHARP approved
service facility. (see p. 66)
1. Remove all packing materials including the
feature sticker (if applicable). Do not remove the
plastic film from the inside of the oven window as
this protects it from dirt. The waveguide cover
prevents food and grease from entering the
waveguide area where it could cause damage.
DO NOT REMOVE.
2. Place oven on a secure, level surface, strong
enough to take the oven weight, plus the heaviest
item likely to be cooked in the oven.
3. The minimum height
of free space
necessary above the
top sur face of the
oven is 19cm.
4. The oven door may become hot during cooking.
Place or mount the oven so that the bottom of the
oven is 85cm or more above the floor.
5. Do not place the oven where heat, moisture or
high humidity are generated, (for example, near
or above a conventional oven) or near
combustible materials (for example, curtains). Do
not block or obstruct air vent openings. Do not
place objects on top of the oven.
6. Make sure the power supply cord is undamaged
(See IMPORTANT: ELECTRICAL CONNECTION!
below) and that it does not run under the oven or
over any hot or sharp surfaces. 
7. The socket must be readily accessible so that it
can be easily unplugged in an emergency.
8. Do not use the oven outdoors.
BUILDING-IN-KIT.
The R-884M microwave oven is not designed to be
built-in to a kitchen unit.
An installation frame is available for R-874M and
R-84STM which enables the microwave oven to be
integrated within a kitchen unit.
The microwave ovens are not designed to be built
above or near a conventional oven.
SHARP recommend the use of the build in kit,
EBR-4700 (R-874M) or EBR-47ST (R-84STM),
available from your SHARP dealer.  Only the use of
this frame will guarantee the quality and safety of
the oven. When building, follow installation
instructions carefully.
IMPORTANT! ELECTRICAL CONNECTION.
• Do not allow water to come into contact with the
power supply cord or plug.
• Insert the plug properly into the socket.
• Do not connect other appliances to the same
socket using an adaptor plug.
• If the plug or socket is loose or the power supply
cord is damaged, it must be replaced with a
special cord. The exchange must be made by an
authorised SHARP service agent. 
• When removing the plug from the socket always
grip the plug, never the mains lead as this may
damage the power supply cord and the
connections inside the plug.
• This product is fitted with a re-wireable plug.
Should it not be suitable for the socket outlet in
your home, remove the plug and fit an
appropriate type, observing the wiring code given
in `To replace the mains plug’ on page 65.
If you wish to remove or replace the plug supplied,
ensure the plug is removed properly and not cut off.
When replacing the plug please ensure that you use
a BSI or ASTA approved plug to BS1363, this should
be fitted with a brown coloured 13 amp fuse
approved by BSI or ASTA to BS1362. If you have
any doubt about electrical connection seek the help
of a qualified electrician. 
WARNING: THIS APPLIANCE MUST BE
EARTHED
To wire an appropriate plug, follow the wiring code
given in `To replace the mains plug’ on page 65.

Pacemaker: If you have a heart pacemaker,
consult your doctor or the pacemaker manufacturer
prior to oven use.
Warning: Only allow children to use the
oven without super vision when
adequate instructions have been given
so that the child is able to use the oven
in a safe way and understands the
hazards of improper use.
Oven Use:
• The oven is for domestic food preparation only.
Never operate when empty, except as directed in
the operation manual (see page 11).
• Do not leave or store anything inside the oven
when not in use.
• Never attempt to use the oven with the door

the door safety latches.
• Never operate the oven with any object caught in
the door.
• Do not insert fingers or objects in the holes of the
door latches or air-vent openings as this may
damage the oven and cause an electric shock.     
• If water or food drops inside the air-vent openings
switch off the oven immediately, unplug it and call
SHARP approved service facility

cleaning make sure they are not hot.
Fire:  If smoke is observed, switch off and
unplug the appliance and keep the door
closed  in order to stifle any flames.

can result in delayed eruptive boiling,
therefore care has to be taken when
handling the container. Stir the liquid prior
to and during heating/reheating, let liquid
stand in the oven after cooking.

The heating category (a letter A to E) developed by
MAFF (Ministry of Agriculture, Fisheries and Food)
with microwave oven and food manufacturers
indicates the ability of the oven to heat small
quantities of food (up to 500g [1lb 2oz]). It does not
represent the general performance of the oven.

Introduction:
Water, sugar and fat in food absorb microwaves which
causes them to vibrate. This creates heat by friction, in
the same way your hands get warm when you rub
them together.
Outer areas of food are heated by microwave energy,
and remaining portions by conduction.  It is, therefore,
important to turnrearrange or stir food to ensure
even heating.  Where recommended allow food to
stand.  This is not optional but necessary to ensure
thorough cooking and is particularly important for
dense food, such as joints of meat.
Microwaves pass through non-metallic dishes and
utensils and heat the food inside the dishes.
Microwaves are reflected by metal.  The oven is lined
with metal and has a fine metallic mesh in the door to
prevent microwave leakage. Metallic dishes are not
suitable for microwaving. Only use utensils that are
suitable for microwave ovens.
(See suitable cookware, pages 27 - 28).
Power level: The microwave power level is varied
by the microwave energy switching on and off.
When using power levels other than 100% you will
be able to hear the microwave energy pulsing on
and off as the food cooks or defrosts. 
IMPORTANT: The microwave power level will default
to 100% unless you press the MICRO. POWER key
to the desired setting.
TO CHECK THE POWER LEVEL:
To check the microwave power level during cooking,
press the MICRO. POWER key. As long as your
finger is pressing the MICRO. POWER key the power
level will be displayed. The oven continues to count
down although the display will show the power level.
To change the power level for cooking, enter
the required time and then press the
MICRO. POWER key.
For example:
Your oven has 5 power levels. To choose the power
level for cooking, follow the advice given in the
recipe section. Generally the following
recommendations apply:
100% - (HIGH output = 900W) used for fast
cooking or reheating e.g. for casseroles, hot
beverages, vegetables etc.
70% - (MEDIUM HIGH output = 630W) used for
longer cooking of dense foods such as roast joints,
meat loaf and plated meals, also for sensitive dishes
such as cheese sauce and sponge cakes.
50% - (MEDIUM output = 450W) for dense foods
which require a long cooking time when cooked
conventionally, eg. beef dishes, it is advisable to use
this power setting to ensure the meat will be tender.
30% - (MEDIUM LOW output = 270W Defrost
setting) to defrost, select this power setting, to ensure
that the dish defrosts evenly. This setting is also ideal
for simmering rice, pasta, dumplings and cooking
egg custard.
10% - (LOW output = 90W) For gentle defrosting,
eg. cream gateaux or pastry.
