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

• 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.

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 turn, rearrange 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).

R-8740M O/M 5/15/01 12:41 PM Page 5

6

Your oven has 6 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.

0% - (0 W, no microwave power)

For setting standing time.

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 MICROWAVE
key to the desired setting.

TO CHECK THE POWER LEVEL: To check the
microwave power level during cooking, press the
MICROWAVE key. As long as your finger is
pressing the MICROWAVE key the power level will
be displayed. The oven continues to count down
although the display will show the power level.
