MAFF HEATING CATEGORY
Model R-952M has a microwave output power of
900 Watts; heating category E.
The heating category (a letter A to E) was
developed by MAFF (Ministry of Agriculture,
Fisheries and Food) with microwave oven and food
manufacturers and 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.

Food packs carry cooking instructions for heating
categories A to E.  Follow instructions for the letter
corresponding to the oven's heating category. 
The higher the output power and heating category
of the oven the less heating time is required, as
shown opposite.
Your oven is fitted with a 12 hour clock. To set the time of day, follow the guidelines given in the example below:
EXAMPLE:
To set the time of day, 12:35.

NOTES:
• If the oven is in cooking or timer mode and you wish to know the time of day, press the AUTO START/CLOCK key.
As long as your finger is pressing the key, the time of day will be displayed.
• If the electrical power supply to your microwave is interrupted, plug in the oven again, then open and close the door.
The display will show “ .0”. If this occurs during cooking, the programme will be erased. The time of day will also be
erased.

MICROWAVING - INTRODUCTION
Water, sugar and fat in food absorbs the microwaves
and causes 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  food are heated by microwave
energy and the remaining portions by conduction.  It is
important to turnrearrange or stir food to ensure
even heating.  Where recommended, allow food to
stand, this is not optional but is necessary to ensure
thorough cooking. It is particularly important for dense
food, such as joints of meat.
NOTES:
• 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. 
• See SUITABLE COOKWARE, page 24-25.

MICROWAVE POWER LEVELS
To operate the microwave function:
• Enter the required cooking/defrosting time. 
• Select the power level by pressing the
MICROWAVE POWER LEVEL key.
There are 5 microwave power levels (see below).
• Press START/AUTO MINUTE key.
IMPORTANT:
The microwave power level will default to 100% (HIGH)
unless you press the MICROWAVE POWER LEVEL key
to the desired setting. To help you decide which power
level is suitable, refer to the charts in the Cookery Book.
NOTES:
• 
To check the microwave power level during
cooking/defrosting press the MICROWAVE
POWER LEVEL 
key. The power level will be
displayed as long as the key is pressed. This
does not affect the programme or cooking time.
• Power level: The microwave power level is
varied by the microwave energy switching on 
and off. When using the power levels other than
100% (HIGH) you will be able to hear the
microwave energy pulsing on and off as the
food cooks or defrosts.

MICROWAVE COOKING:
EXAMPLE:
To cook on 10% (low) power for 2 minutes.
To defrost foods not included in the Auto Defrost menu, use microwave power levels 30%
(MEDIUM LOW)  or  10% (LOW). Stir or turn food at least 2-3 times during defrosting.
After defrosting, wrap in aluminium foil and leave to stand until thoroughly defrosted.
Refer to the defrosting charts in the Cookery Book.

CONVECTION COOKING
The oven cavity, door, turntable, turntable support, racks and dishes will become very hot.  Use thick oven gloves
when removing the food or turntable from the oven to prevent burns.
NOTES:
• Once the oven has started you can find out the temperature you have programmed by pressing the
CONVECTION TEMPERATURE key. The temperature will appear on the display. This will not affect the
programme or cooking time.
• If you wish to preheat and cook at a different temperature, press the CONVECTION TEMPERATURE key until the
desired temperature is displayed after step 5 in the above example.
• After cooking is complete, the cooling fan will continue working for a short time to lower the temperature of
the electrical and mechanical components.  The display will show “NOW COOLING”
WARNING:
Your oven can be used as a
conventional oven using the
convection facility.
The temperatures available in degrees Centigrade are:
250°C, 230°C, 220°C, 200°C, 180°C, 
160°C, 130°C, 100°C,  70°C, 40°C.
NOTES:
• CONVECTION cooking is ideal for cooking Victoria sandwich cakes, buns, biscuits, scones and for proving
bread at 40˚C.
• When using the CONVECTION facility, all metal cookware can be used. See SUITABLE COOKWARE
page 24-25. To achieve the best results when cooking by CONVECTION, always use the low metal
rack for one layer cooking, and the high rack and low rack for two layer cooking.
• When first using the convection, smoke and odour will be given off.  To avoid this happening when
food is being cooked, heat the oven convection 250˚C without food for approximately 20 minutes.
EXAMPLE:
To bake at 200°C for 20 minutes.
1. Input the desired
cooking time, of 20
minutes.
3. Press the START/AUTO MINUTE
key and the oven will cook 20
minutes at 200˚C.
