Cooking Sequence.
1. Touch SENSOR COOK pad.
NOTE:
The oven should not be operated on SENSOR
COOK immediately after plugging in the unit.
Wait two minutes before cooking on SENSOR COOK.
2. Select desired Sensor setting.
3. Touch START pad.
The coil of shut-off relay (RY10, RY14) is energized,
the MG fan motor and cooling fan motor are turned on,
but the power transformer is not turned on.
4. After about 16 seconds, the cook relay (RY-1) 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 remove
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 sound.
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.
EASY WAVE OPEN
Below are criteria for wave sensor to open drawer.
1. Motion sensor function requires 2 consecutive hand
waves.
2. Each hand wave must completely clear the motion
sensor view.
3. The second hand wave must be less than 2 sec interval
from the first hand wave.
4. The second hand wave must be more than 100ms
interval from the first hand wave.
5. Duration of each hand wave infront of the sensor view
must be less than 250ms.
6. The distance of hand should be less than 4 inches away
from surface of door. The effective distance is reduced
if skin color is darker. (For the best results, use the side
of the hand with the lightest skin pigments/color)
