Put your food in your Sharp microwave oven and close the microwave door. Enter the cooking time, minutes followed by seconds.
Press the "Power Level" button once to confirm that the power level is set on "high." If the display reads "P-100," the power level is already set on "high" and does not need to be reset.
Press the "Stop/Clear" button two times if the power level reads "P-90" or less.
Re-enter the cooking time, and press the "Power Level" button. The power level will now read "P-100," indicating that the power level on your Sharp microwave has been reset to "high."
Press "Start" to begin cooking your food.
