IMPORTANT SAFETY INSTRUCTIONS
Pacemaker: If you have a heart pacemaker,
consult your doctor or the pacemaker
manufacturer prior to oven use.
Oven Use:
•The oven is for domestic use only.
•Never operate when empty, except as directed
in the ‘Grill cooking’ section on page 12.
•Do not leave or store anything inside the oven
when not in use.
•Never attempt to use the oven with the door
open. It is important not to force or tamper
with 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 the oven off immediately,
unplug it and call a SHARP approved service
facility. (See page 31).
•Never move the oven while it is operating.
•The door, outer cabinet, oven cavity, turntable,
dishes, accessories and especially the grills will
become very hot during operation. Care
should be taken to avoid touching these areas.
To prevent burns, always use thick oven gloves.
Before 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.
PLEASE READ CAREFULLY AND KEEP FOR FUTURE REFERENCE
LIQUIDS: Microwave heating of
beverages 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 for at least 20
seconds in the oven after cooking.
WARNING: Do not allow children
to use the oven without supervision
until 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.
INSTALLATION
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, until it has
been repaired by a SHARP trained
engineer. (See page 31 for details).
1. Remove all packing materials including the
feature sticker (if present). 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 THE
WAVEGUIDE COVER.
2. The oven door will become hot during
cooking. Place or mount the oven so that the
bottom of the oven is 85cm or more above
the floor. Ensure the surface or mounting
position is strong enough to take the oven
weight, plus the heaviest item likely to be
cooked in the oven.

INSTALLATION
3. The minimum
height of free space
necessary above the
top surface of the
oven is 19cm.
4. 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.
5. Make sure the power supply cord is
undamaged (See “ELECTRICAL
CONNECTION” opposite).
Do not allow the power supply cord to
run over any hot or sharp surfaces, such
as the hot air vent area at the top rear of
the oven.
6. The socket must be readily accessible so that
it can be easily unplugged in an emergency.
7. Do not use the oven outdoors.
BUILDING-IN-KIT.
An installation frame is available which enables
the microwave oven to be integrated within a
kitchen unit.
The microwave oven is not designed to be built
above or near a conventional oven.
SHARP recommend the use of the build in kit
EBR-4900, available from your SHARP dealer.
Only the use of this frame will guarantee the
quality and safety of the oven.
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 power supply cord is damaged, it must be
replaced by a SHARP approved service facility
or a similarly qualified person to avoid a hazard.
•When removing the plug from the socket
always grip the plug, never the cord as this may
damage the power supply cord and the
connections inside the plug.
•If the plug fitted to your oven is a rewireable
type and in the event of the socket outlet in
your home not being compatible with the plug
supplied, remove the plug properly (do not
cut off).
•If the plug fitted to your oven is a non-
rewirable type and in the event of the socket
outlet in your home not being compatible with
the plug supplied, cut-off the mains plug.
•Refit with a suitable type, observing the wiring
code given in `To replace the mains plug’ on
page 31.
IMPORTANT!
•The fuse from the cut-off plug should be
removed and the plug disposed of in a safe
manner.
•Under no circumstances should the cut-off
plug be inserted into a socket outlet as a
serious electric shock may occur.
•The plug must not be used without the fuse
cover fitted.
•If you have any doubt about your microwave
oven obtain the help of a qualified electrician.
•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 31.

HEATING CATEGORY
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.
HOW YOUR OVEN WORKS
Microwaves are energy waves, similar to those
used for TV and radio signals.
Electrical energy is converted into microwave
energy, which is directed into the oven cavity via
a waveguide. To prevent food and grease entering
the wave guide it is protected by the waveguide
cover.
Microwaves cannot pass through metal, because
of this the oven cavity is made of metal and there
is a fine metal mesh on the door.
During cooking the microwaves bounce off the
sides of the oven cavity at random.
Microwaves will pass through certain materials,
such as glass and plastic, to heat the food.
(See ‘Suitable Cookware’ on page 25).
Water, sugar and fat in food absorb microwaves
which cause them to vibrate. This creates heat by
friction, in the same way your hands get warm
when you rub them together.
The outer areas of the food are heated by the
microwave energy, then the heat moves to the
centre by conduction, as it does in conventional
cooking. It is important to turn, rearrange or stir
food to ensure even heating.
Once cooking is complete, the oven
automatically stops producing microwaves.
Standing time is necessary after cooking, as it
enables the heat to disperse equally throughout
the food.
