Note:
The On/Off time ratio does not exactly correspond
to the percentage of microwave power, because
approx. 3 seconds are needed for heating up the
magnetron filament.
GRILL COOKING CONDITION
TOP GRILL (Figure O-3a)
In this condition the food is cooked by the grill heating
element . Programme the desired cooking time by touch-
ing the TIME keys and touch the GRILL key once. When
the START key is touched, the following operations occur:
1. The numbers on the digital read-out start the count
down to zero.
2. The oven lamp, cooling fan motor and turntable motor
are energized.
3. The relay RY3 is energized and the main supply
voltage is applied to the top grill heating elements.
4. Now, the food is cooked by the top grill heating ele-
ments.
NOTE: The convection cooking condition will be curried
out simultaneously until the temperature of the
oven cavity rise to 220˚C.
CONVECTION COOKING CONDITION
(Figure O-4)
PRE-HEATING (by 40˚C - 130˚C)
Programme the desired convection temperature of 40˚C
- 130˚C by touching CONVECTION key. When the START
key is touched, the following operations occur:
1. The relays RY1, RY6 and RY7 are energized, the oven
lamp, turntable motor, fan motor and convection motor
are turned on.
2. The relay RY4 is energized and the main supply
voltage is applied to the convection heating element.
3. After the temperature of oven cavity rises to the se-
lected one, the oven will continue to turned the
convection heating element on and off to maintain the
temperature for 30 minutes.
PRE-HEATING (by 160˚C _ 250˚C)
Programme the desired convection temperature of 160˚C
- 250˚C by touching CONVECTION key. When the START
key is touched, the following operations occur:
1. The relays RY1, RY6 and RY7 are energized, the oven
lamp, turntable motor, fan motor and convection motor
are turned on.
2. The relay RY4 and RY3 are is energized and the main
supply voltage is applied to the convection heating
element and the grill heating elements.
3. After the temperature of oven cavity rises to the se-
lected one, the oven will continue to turned the
convection heating element on and off to maintain the
temperature for 30 minutes. And simultaneously the
grill heating element will be operated at 10% power
output.
CONVECTION COOKING (by 250˚C)
Programme the cooking time by touching TIME keys. And
then programme the convection temperature of 250˚C by
touching CONVECTION key. When the START key is
touched, the following operations occur:
1. The relays RY1, RY6 and RY7 are energized, the oven
lamp, turntable motor, fan motor and convection motor
are turned on.
2. The relay RY4 and RY3 are energized and the main
supply voltage is applied to the convection heating
element and the grill heating element.
3. The oven will continue to turned the convection heating
element on and off to maintain the temperature for the
programmed cooking time. And simultaneously the
grill heating elements will be operated at 10% power
output.
CONVECTION COOKING (by 40˚C _ 230˚C)
Programme the cooking time by touching TIME keys. And
then programme the desired convection temperature of
40˚C 230˚C by touching CONVECTION key. When the
START key is touched, the following operations occur:
1. The relays RY1, RY6 and RY7 are energized, the oven
lamp, turntable motor, fan motor and convection motor
are turned on.
2. The relay RY4 is energized and the main supply
voltage is applied to the convection heating element.
3. The oven will continue to turned the convection heating
element on and off to maintain the temperature for the
programmed cooking time.
DUAL COOKING CONDITION
MICROWAVE AND CONVECTION (Figure O-5a)
Programme the desired cooking time by touching the
TIME keys. Touch the DUAL CONV./GRILL key once.
Select the microwave power level by touching the MICRO-
WAVE POWER LEVEL key. And select the convection
temperature by touching the CONVECTION key.
NOTE: The 100% microwave power level can not be
selected.
When the START key is touched, the following operations
occur:
1. The numbers on the digital read-out start the count
down to zero.
2. The oven lamp, fan motor, turntable motor and con-
vection motor are energized.
3. The relay RY4 will be energized and the main supply
voltage is applied to the convection heating element.
4. The relay RY2 is energized and the microwave energy
is generated by magnetron.
5. Now, the food is cooked by microwave and convection
energy simultaneously.
MICROWAVE AND TOP GRILL (Figure O-5b)
Programme the desired cooking time by touching the
TIME keys. Touch the DUAL CONV./GRILL key twice.
Select the microwave power level by touching the MICRO-
WAVE POWER LEVEL key. When the START key is
touched, the following operations occur:
1. The numbers on the digital read-out start the count
down to zero.
2. The oven lamp, fan motor and turntable motor are
energized.
3. The relay RY3 is energized and the main supply
voltage is applied to the grill heating elements.
4. The relay RY2 is energized and the microwave energy
is generated by magnetron.
5. Now, the food is cooked by microwave and grill simul-
taneously.
