How do I use the

It came with a small plastic measuring cup. The ratio for that is 1 cup rice to 1 cup water (using the measuring cup for both items). Measure out your rice first, BUT for best results you need to rinse your rice several times (I do three times or until the water is fairly clear). Place rinsed rice in cooker and add equal amout of water . You can also add in your butter and salt at this time if you wish. put lid on cooker,plug it in and push the little lever down (it'll click). It will cook for about 20 minutes and the lever will pop up on its own. Don't do anything yet! you need to wait about 10-15 minutes more, or at least until the steam stops before you open the lid. The rice should be cooked perfectly.
There will (with this model) be a light brown crust on the bottom of the pan, butthe instruction manual said that it was a normal occurance (but it is a buggar to get that off-soaking for a couple hours helps).
I really like using rice cookers because they do a great job in cooking the rice. I hope this clarified how to use this model.
