Note: During alternate Microwave/Convection opera- tion, the convection heater is energized only if the cavity temperature drops below the set tem- perature.

SENSOR COOKING CONDITION

Using the SENSOR COOK function, the foods are cooked 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 calculate 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 in- creases gradually. When the resistance reaches the value set according to the menu, supplementary cook- ing is started.

The time of supplementary cooking is’.determined by experiment with each food category and inputted into the LSI.

An example of how sensor works:

1.Broccoli at room temperature. Vapor is emitted very slowly.

2.Heat broccoli. Moisture and humidity is emitted rapidly. You can smell the aroma as it cooks.

3.Sensor detects moisture and humidity and calcu- lates cooking time and variable power.

Cooking Sequence.

1.Touch SENSOR COOK pad.

NOTE:The oven should not be operated on SEN- SOR COOK immediately after plugging in the unit. Wait five minutes before cooking on SENSOR COOK.

2.Select desired Sensor setting.

3.Touch START pad.

The coil of shut-off relays(RY2,RY5) are energized, the oven lamp and cooling fan motor are turned on, but the power transformer is not turned on,

4.After about 16 seconds, the cook relay (RYI) is energized. The power transformer is turned on, microwave energy is produced and first stage is started.

The 16 seconds is the cooling time required to re- move any vapor from the oven cavity and sensor. NOTE: During this first stage, do not open the door

or touch STOP/CLEAR pad.

5.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.

6.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,

7.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.

COMPU COOK

COMPU COOK will automatically compute the oven temperature, microwave power and cooking time for baking, roasting and broiling.

Set the desired program by touching the COMPU COOK pad, and number pad.

Enter the weight by touching the Number pads

When the START pad is touched, the following oper- ations occur:

1.The COOK indicator will light and the Convection Fan Symbol will rotate.

2.The cooking time will appear on the display and start counting down to zero.

The cooking time is adjusted automatically ac- cording to the weight of the food.

3.The shut-off relays (RY2, RY3, RY4 and RY5) are energized, turning on the oven lamp, turntable motor, cooling fan motor and convection motor. The power supply voltage is added to the con- vection heater.

4.Now, the oven is in the convection cooking mode.

5.When the oven temperature has reached the pro- grammed convection temperature, the oven goes into the programmed cooking mode.

6.At the end of the COMPU COOK cycle, the damper is returned to the open position and the oven will go to the off condition.

The cooling fan will remain on until the oven has cooled.

EASY DEFROST COOKING

The EASY DEFROST key is a special function key to defrost meats and poultry faster and better.

EASY DEFROST key has 4 defrost stages.

EASY DEFROST automatically defrosts roast beef, etc. When EASY DEFROST is selected and the food weight is entered by using the number pads, the oven will cook according to the special cooking sequence.
