I have lost my manual for a Sharp carosel R340B, its an older model circa year 2000. The numbers are worn, I have bought a tupperware microwave steamer that is suitable for amicrowave of 800watt my model is 1000watts. I assume you can adjust the power to high and low. As mentioned numbers worn on power button-want to know how to lower the wattage to 800watts so I can sue my new steamer. Thanks Fiona
