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. 36)
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 necessar y
above the top surface 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).  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.
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.
This oven is not designed to be built-in to a kitchen
unit.
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 a
SHARP approved service facility. 
• 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.
• If the fitted mains plug to your oven is a rewireable
type and in the unlikely event of the socket outlet in
your home not being compatible with the plug
supplied, remove the plug and fit an appropriate
type, observing the wiring code given in `To replace
the mains plug’ on page 35.
If you wish to remove or replace the plug supplied,
ensure the plug is removed properly and not cut off. 
• If the plug fitted to your oven is a non-rewirable
plug and in the unlikely event of the socket outlet
in your home not being compatible with the plug
supplied, cut-off the mains plug and fit an
appropriate type, observing the wiring code given
in `To replace the mains plug’ on page 35.
Danger:
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 - IMPORTANT NOTE
Please note both the Operation Manual and Cookbook
supplied specify 900W (IEC 60705) microwave
output power. This applies only when the oven is
operated on a 230-240V supply.
If your supply is less than 230-240V, it may be
necessary to increase the cooking time when following
the Operation Manual and Cookbook instructions.
WARNING: THIS APPLIANCE MUST BE
EARTHED
To wire an appropriate plug, follow the wiring code
given in `To replace the mains plug’ on page 35.

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:
• Never operate when empty, except as directed in
the operation manual (see page 9).
• 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 off the oven immediately, unplug it and call
SHARP approved service facility
. (See page 36).
• Never move the oven while it is operating.
• Do not touch the oven door, outer cabinet, rear
cabinet, oven cavity, ventilation openings,
accessories and dishes during GRILL,
CONVECTION and  DUAL COOKING modes,
unless wearing thick oven gloves, as they will
become hot. 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. 
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 in the oven after cooking.
IMPORTANT SAFETY INSTRUCTION READ CAREFULLY AND KEEP FOR FUTURE REFERENCE
MICROWAVING
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 17 - 18).
