Rice Cooker question. Can you help me?

They want you to rinse off the starch so that the rice sticks less. Short grain rice is stickier than long grain, so it depends of which type you use. I go with 1 part rice to 1-1/2 or 1-3/4 parts water. Don't know what to tell you about using their measuring cup. A pint's a pound the world around.....
