[6] 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.
[7] AUTOMATIC COOKING
Auto Cook functions automatically work out the correct cooking mode
and cooking time and/or cooking temperature. They will cook accord-
ing to the special cooking sequence.
[8] 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 intermittently, as shown in the table below.
This is to protect the oven door against temperature rising.
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 key 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 micro-
wave or the grill will be reduced to 70% after 20 minutes
when the oven is started at first.
[9] FAN MOTOR OPERATION
(in Grill, Convection and Dual mode)
When oven is stopped during cooking, or after the cooking is com-
pleted, the fan motor will operate if the oven cavity temperature is
above 120
°
C, and the fan motor will stop if the oven cavity tempera-
ture is below 105
°
C.
[10] 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 cook-
ing or 250
°
C preheating, the convection motor will operate for maxi-
mum 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.
