Twin mode
The upper and lower modes operate at the same time. It is possible to set which
mode activates first. When one of the dishes has finished cooking in twin mode
and you would like to change the cooking time or temperature of the other
partition, turn the operation knob to select the mode (upper or lower) that you
would like to continue operating. Divider should be inserted.
Twin mode 1
The upper mode begins operating first. If the function Button is pressed or if
15 seconds elapse after the upper mode is set and there has been no further
adjustment, the oven begins the lower mode.
Twin mode 2
As the upper mode starts, if the function Button is pressed or if 15 seconds
elapse and there has been no further adjustment, the oven moves to the lower
mode. The upper and lower modes operate at the same time.
