INTRODUCTION TO MICROWAVE
COOKING
• Microwaves are invisible waves of
electromagnetic energy similar to radio
waves. Instead of being converted to sound
as in a radio or mobile phones, it is converted
into a heat source which heats food from
the inside.
• Microwaves cook because food molecules
of water, fat and sugar react to the energy
provided by the microwaves. That energy is
absorbed by the food causing the molecules
to vibrate quickly. This movement creates
friction which causes the food to heat up and
therefore cook.
• The energy in a microwave is distributed
evenly throughout the cavity.
• Microwave cooking is considered the 'cool'
cooking method as only the food gets hot and
surrounding air stays cool.
• Microwaves are safe and can be economical.
• Microwave ovens don't need preheating
therefore the kitchen stays cooler. Cooking
is cleaner with less odours and washing
up is reduced.
• Microwave ovens cook foods rapidly. Some
foods are better cooked in a microwave
oven as they retain more flavour, texture and
goodness, such plain fish fillets, soft fruit,
vegetables and fat free cakes.
• In a microwave the heat is produced INSIDE
the food. In all other conventional cooking
methods, heat is applied from OUTSIDE
through transference of heat by convection
or radiation.
• Microwave energy penetrates the food to
a depth of about 25mm. Small foods under
5cm in diameter such as eggs are penetrated
to the centre from all sides. In larger foods,
energy creates heat in the outer layer; this
then moves to the centre by conduction, as it
does with conventional cooking.

SETTING THE CLOCK
When the power is activated, the LED
will display 1:00. Press the CLOCK button
once or twice to set the digital clock to
24 or 12 hours cycle respectively.
EXAMPLE: To set the oven clock time to 8:30.
1. Press CLOCK button once. Pressing once
will show 24 hours and twice will show
12 hours.
2. Turn TIME/WEIGHT dial to indicate the
hour digit 8. Press the clock button to set
the hour figure.
3. Turn TIME/WEIGHT dial to indicate the
minute digits until the screen shows ": 30"
4. Press CLOCK to confirm the setting.
NOTE
You can press the CLOCK button once to
check clock time during cooking.
