1. Cooking Sequence.
1. 1.Operate the oven in sensor cooking mode by referring to the
operation manual.
NOTE: The oven should not be operated on SENSOR immediately
after plugging in the unit. Wait two minutes before cooking on
SENSOR.
2. The coil of shut-off relay (RY-1) is energized, the turntable motor,
oven lamp and cooling fan motor are turned on, but the inverter unit
is not turned on.
3. After about 16 seconds, the cook relay (RY-2) is energized. The
inverter unit 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.
4. When the sensor detects the vapor emitted from the food, the dis-
play switches over to the remaining cooking time and the timer
counts down to zero. At this time, the door may be opened to stir,
turn, or season food.
5. When the timer reaches zero, an audible signal sounds. The shut-
off relay and cook relay are de-energized and the inverter unit,
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. The fan motor will operate for one minute after cooking.
[4] POWER OUTPUT REDUCTION
1. In 100%, 90%, 80% and 70% power levels, output power will grad-
ually be reduced to avoid overheating.
1-1. For an example of 100% power
After 3 minutes, the output power will be reduced to 70%
gradually.
1-2. For an example of 70% power
After 15 minutes, the output power will be reduced to 60%.
2. In 60% power level, after 30 minutes, the inverter unit will operate
intermittently.
