Place the food on the turntable and close the door. The oven does not start if the door is left ajar.
Press the "Power" button on the control panel. The display shows "P-HI." Tap "Power" to scroll through the available levels. The number shown after "P-" is a rough approximation of the power level percentage. For example, "P-50" is approximately 50 percent power.
Type a cooking time using the number buttons and press "Start." The oven hums and begins cooking at your chosen power level for the amount of time you chose during this step.
