Overboiling I measured 3/4 cup of rice and filled the water to a little over the 2 cup mark (for 2 and 1/4). Overboiled continuously during cooking making a big mess.

All rice cookers are very easy to operate without the manual.
First just measure the amount of rice you want to cook. 1, 2 or 3 cup then wash couple time and rinse very good . Put in then fill with cold water to the mark line indicate cup. (Equal the amount of rice)
Then just press cook. After it pop up that mean it's cooked. Then open and turn the rice thoroughly, let it open for 6-10 minutes then closed it. It's ready to serve.
If the rice is too soft, that mean too much water. Use less water next time.
If the rice is too hard or not fully cook, that mean too less water. Use more water next time.
Any left over, just leave it in and on to keep warm.

Good luck and enjoy

I have this rice cooker (it's very small) and the original instruction booklet:

HOW TO USE
1. Measure rice with measuring cup. One cup of uncooked rice will make about 3 cups of cooked rice.
2. Wash rice 4 or 5 times with fresh water in another bowl. Wash until water becomes relatively clear.
3. Put rice and water into the pan. As a rule, add water to uncooked rice in the following standard proportions.

2 cups rice to 2 - 2 1/2 cups water
3 cups rice to 3 - 3 1/2 cups water

4. Place the pan directly on the internal heating plate, and make sure that the pan is properly located on the heating plate by turning it slightly to the right and left as shown. (see CAUTION) . Before placing the pan in the cooker, wipe off water and moisture from the outside (especially the bottom) of the pan.
5.Put on the lid.
6.Insert the plug end into a wall outlet.
7.Push the switch button to the "ON" position. Make sure the pilot lamp is on. When the rice is done, the switch will turn off automatically, the lamp will go out and a click will be heard.
8.Even after the switch is off, leave the lid on for at least 15 minutes more. During that period, the rice will be properly steamed to a fluffy character by the retained heat.

SOME HELPFUL HINTS
• Always tasty rice

With your National Automatic RICE•O•MAT you can have uniformly cooked rice ... you can even cook rice to your personal taste and preference. Taste and degree cooked depend upon the quality of the rice and the length of time it is soaked before being placed into the cooker. Add more water than specified for softer, more fluffy rice; less water for firmer rice.
• Rice may bubble over ...

If you use too much water or if the cooker is tilted, rice may bubble over. To prevent rice from bubbling over, add water using the cup included (refer to How to use, Item 3.)

HOW TO CLEAN THE COOKER
Do not immerse the body into water or spray water onto it. Wipe it clean with a wet dishcloth soaked in hot water.

hi,

Tips on cooking rice:

You estimate first how many rice you are cooking then follows how many water you will be needing to cook it.

In an average, 1 cup of rice per person (depending on the persons appetite) = 2 cups of water. Rinse first the rice about 2 - 3 times to remove unwanted stuffs then start pouring and measuring the water.

Note:

1 cup rice = 2 cups water (common ratio), but there are also type of rice that requires more water or less water. You can adjust next time the water depending on the result. If the rice is a little bit hard then add more water the next time you cook. If the result is too soft then minus the water.

Hope you can cook now a perfect rice! Bon appetite!

There are many types of rice. Follow specific directions for variety used.
2. Accurately measure rice and water then combine in rice bowl.
Pour specified amount of water in water reservoir. Cover and steam.
3. For softer rice, increase by 1 – 2 tablespoons the water mixed with rice
by the specified amount of water on the chart. For firmer rice decrease
water mixed with rice by the same amount.
4. Check doneness and consistency of rice at minimum time specified
for each type, stirring rice at the same time.
5. When checking/stirring rice, be careful not to drip the condensate into the
rice bowl which would reduce the quality and flavor of the steamed rice.
6. Use only clean water in water reservoir
7. Rice may be seasoned with salt, pepper or butter after steaming.
Combined In Rice Bowl Approx. Time
Type of Rice Rice Amount Water (Minutes)
Brown
Regular 1/2 cup 1 cup 42 – 45
Parboiled 1 cup 1-1/2 cups 45 – 50
Long Grain and Wild Rice Mix
Regular (6 oz. pkg.) Mix 1-1/2 cups 50 – 55
Quick Cooking (6-1/2 oz. pkg.) Mix 1-3/4 cups 18 – 20
Instant 1 cup 1-1/2 cups 15 – 18
White
Regular 1 cup 1-1/2 cups 45 – 50
Long Grain 1 cup 1-2/3 cups 50 – 55

1 cup of rice in the rival cup does NOT equal 1 cup of rice in a regular measuring cup. I lost mine too and I've found that using 3/4 cup of a regular measuring cup works with the lines on the inside of the pot

I have a Toastmaster 3 cup rice cooker but think the ratio would be the same.
Long grain white rice - 2 rice measuring cups - water to 2 cup line = 8 (1/2 cup) servings
3 rice measuring cups - water to 3 cup line = 12 (1/2 cup) servings

Long grain brown rice - 1 1/2 Rice measuring cups - water to 3 cup line - 6 (1/2 cup) servings

For fluffy rice: After cooker shuts off, allow rice to stand for approx. 15 minutes, covered, before serving.

Hope this helps

The measuring cup for my Rival RC100 holds 6 oz (volume of water to the top rim). The markings on the inside of the pot (1 through 5) seem to hold about 12 oz each.
(that is: the 1 line holds 12.2 oz, the 5 line held 57 ounces of water)
close enough to the standard 2 to 1 water to rice ratio.
I put in about 1.7X as much water (by volume) as brown rice, and it comes out very good for me. (1 cup rice to 1 3/4cup water).

From the users guide for the 550 FOR BROWN RICE RICE: 2 half cups WATER: To 2 mark, plus 3/4 cup TIME: 32 minutes MAKES: 2 cups RICE:4 cups WATER: To 4 mark, plus 3/4 cup TIME: 39 minutes MAKES: 8 cups Here are the rest: 6 cups To 6 mark, plus 3/4 cup 44 minutes 13-1/2 cups 8 cups To 8 mark, plus 3/4 cup 48 - 49 minutes 15 cups 10 cups To 10 mark, plus 3/4 cup 51 - 52 minutes 21 cups Here is a link to the user guide for all the instructions. http://www.blackanddeckerappliances.com/dyn/prod/user-guide/139/RC410%20RC550.pdf
