ON/OFF TIME RATIO
In grill cooking, convection cooking or dual cooking, the
grill heating elements or magnetron operate within a 48
second time base. The following table is the ON / OFF time
ratio at each power output of the grill heating element or
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.
ABSOLUTE HUMIDITY SENSOR (AH SENSOR)
COOKING CONDITION
When the AH sensor is used, the foods are cooked in
microwave cooking mode without figuring time, power
level or quantity. When the oven senses enough steam
from the food, it relays the information to its microproces-
sor which will calculate the remaining cooking time and
power level needed for best results.
When the food is cooked, water vapour is developed.
The sensor “senses” the vapour and its resistance in-
creases gradually. When the resistance reaches the value
set according to the menu, supplementary cooking is
started. The time of supplementary cooking is deter-
mined by experiment with each food category and input-
ted into the LSI.
An example of how sensor works:
1. Potatoes at room temperature. Vapour is emitted very
slowly.
2. Heat potatoes. Moisture and humidity is emitted rap-
idly. You can smell the aroma as it cooks. ;
3. Sensor detects moisture and humidity and calculates
cooking time and variable power.

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 manu of AUTO COOK 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.
