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.
ON/OFF TIME RATIO
In dual cooking, the magnetron operate within a 48 second
time base. The following table is the ON / OFF time ratio
at each power output of the magnetron.

AUTOMATIC COOKING
Auto Cook functions automatically work out the correct
cooking mode and cooking time and/or cooking tempera-
ture. They will cook according to the special cooking
sequence.
POWER OUTPUT REDUCTION
After the same cooking mode is carried out for more than
the basis cooking time, the power output is automatically
reduced by turning the control relays on and off intermit-
tently, as shown in the table below. This is to protect the
oven door against temperature rising.
FAN MOTOR OPERATION (in Grill, Convection
and Dual mode)
When oven is stopped during cooking, or after the cooking
is completed, the fan motor will operate if the oven cavity
temperature is above 120˚C, and the fan motor will stop if
the oven cavity temperature is below 105˚C.
CONVECTION MOTOR OPERATION
If the temperature of oven cavity is higher than 120˚C
after and when operated by 250˚C convection cooking,
250˚C dual convection cooking or 250˚C preheating, the
convection motor will operate for maximum 1 minute until
the oven cavity temperature drops below 105˚C.
ON/OFF TIME RATIO
In grill cooking, convection cooking or dual cooking, the
top heater, bottom heater or magnetron operate within a
48 second time base. The following table is the ON / OFF
time ratio at each power output of the top heaters, bottom
heater or magnetron.

NOTE:
1. If the multiple sequence cooking is carried out in the
same mode, the basis cooking time is calculated from
the first.
2. Even if the cooking is stopped by the STOP button or
opening the door, the basis cooking time is calculated
from the first.
3. If the same cooking mode is repeated within 1 minute
and 15 seconds, the basis cooking time is calculated
from the first.
4. If the same menu of automatic cooking is repeated
within 1 minute and 15 seconds, the power output of
the microwave or the grill will be reduced to 70% after
20 minutes when the oven is started at first.
