OPERATION
DESCRIPTION OF OPERATING SEQUENCE
SENSOR COOKING CONDITION
Using the Sensor Cooking function, the foods are cooked or
defrosted without figuring time, power level or quantity.
When the oven senses enough steam from the food, it
relays the information to its microprocessor which will calcu-
late the remaining cooking time and power level needed for
best results.
When the food is cooked, water vapor is developed. The
sensor “senses” the vapor and its resistance increases
gradually. When the resistance reaches the value set ac-
cording to the menu, supplementary cooking is started.
The time of supplementary cooking is determined by experi-
ment with each food category and inputted into the LSI.
An example of how sensor works (Baked potato):
1. Potatoes at room temperature. Vapor is emitted very
slowly.

2. Heat potatoes. Moisture and humidity is emitted rapidly.
You can smell the aroma as it cooks.
3. Sensor detects moisture and humidity and calculates
cooking time and variable power.
Cooking Sequence.
1. Touch one of the Sensor Cooking pads. And then touch
START/TOUCH ON pad.
NOTE: The oven should not be operated on Sensor Cooking
immediately after plugging in the unit. Wait two
minutes before cooking on Sensor Cooking.
2. The coil of shut-off relays (RY1 and RY3) are energized,
the oven lamp, turntable motor and cooling fan motor are
turned on, but the power transformer is not turned on.
3. After about 32 seconds, the cook relay (RY2) is energized.
The power transformer is turned on, microwave energy
is produced and first stage is started.
The 32 seconds is the cooling time required to remove
any vapor from the oven cavity and sensor.
NOTE: During this first stage, do not open the door or touch
STOP/CLEAR pad.
4. When the sensor detects the vapor emitted from the
food, the display switches over to the remaining cooking
time and the timer counts down to zero.
At this time, the door may be opened to stir food, turn it
or season, etc.
5. When the timer reaches zero, an audible signal sounds.
The shut-off relay and cook relay are de-energized and
the power transformer, oven lamp, etc. are turned off.
6. Opening the door or touching the STOP/CLEAR pad, the
time of day will reappear on the display and the oven will
revert to an OFF condition.
