<p>When the inner glass contains hot water, shiny substances may be found. These are called “flakes”. They come from the thin film on the inner wall of the glass bottle and are formed by the chemically combined mineral contents blended in hot water.<br /> The flakes are not harmful to your health. However, if flaking occurs, clean the product by following the steps below.<br /> (1) Dilute vinegar with lukewarm water by approx. 10% volume, and pour it in the inner glass. Or, dilute citric acid (approximately 10 g) in lukewarm water, and then pour it into the main body. (Do not use vinegar and citric acid together.)<br /> (2) After a few hours have elapsed, wash the main body with a soft brush and then thoroughly rinse it.<br /> (3) Dry the main body completely.<br /> Notes:<br /> 1. For the citric acid, please contact the dealer where you purchased this product.<br /> 2. Even when flaking has not occurred, clean the inner glass periodically using the same procedure as a preventive measure</p> <p><a href="">>> see more detail</a></p>
<ul> <li>Minimum keep warm amount = Minimum cooking amount</li> <li>When you cook rice with minimum amount, you are not able use keep warm function. If you like to use keep warm function, you have to cook more than minimum amount. Keep warm temperature will decrease with small amount. When the keep warm temperature become lower than 140 °F, rice start to spoil due to bacteria growth. Example: JNP-1500 is 3 cup minimum cooking and keep warm amount. If you cook 3 cup, you are not able to use keep warm function. If you cook 6 cup, you can keep warm about a half of the cooked amount.</li> <li>Simple rice cooker:</li> </ul> <p>          - JNP-0550, 0720, 1000 =1 cup<br />           - JNP1500, 1800 = 3cup</p> <ul> <li>Microcomputer type:</li> </ul> <p>          - 10 cup rice cooker = 2cup<br />           - 5.5 cup and 3 cup rice cooker = 1 cup</p>
<p>Check point:</p> <ul> <li>Did you reset cooking function by holding [Cancel] button for 5 seconds?</li> <li>Rice cooker always resume last function.</li> <li>Did you use wrong menu setting?</li> <li>Select correct menu.</li> <li>Is there any a grain or particle on the heater plate?</li> <li>Remove and clean the heater plate.</li> <li>Did you check the inner pan is setting at right position?</li> <li>Inner pan must be set on the proper position.</li> <li>Did you add warm or hot water?</li> <li>Temperature sensor does not work properly.</li> <li>Did you add more than 70g/2oz of ingredients?</li> <li>Ingredients must be chopped finely. Maximum ingredients amount e.g.: 2cup of rice 140g/4oz, 3 cup of rice 210g/6oz.</li> <li>Did you mix ingredients into rice?</li> <li>Mix seasoning but Ingredients must be placed on top of rice.</li> </ul>
<p>That means Lithium battery runs out. Lithium battery is nothing to do with cooking function. As long as power cord is plugged into power source, you may able to use all the features. If you like to replace the battery, contact customer service. Some fee apply.</p>
<ul> <li>Do you use sharp utensil or heavy duty sponge ?</li> <li>It will stcrach the nonstick coating. Use soft sponge.</li> <li>Do you use keep warm function longer than 12 hours ?</li> <li>Moisture in rice penetrate through the non-stick coating and then lift up from the inner pan material.</li> <li>Do you cook brown rice ?</li> <li>Waxy layer (Rice-bran oil) is also easy to panatrate through the non-stick coating.</li> <li>Do you add any spice, salt, butter, oil or vinegar ?</li> <li>Adding the seasoning is deteriorating the non-stick coating.</li> <li>Do you clean inner lid and outer lid every use ?</li> <li>Some models have gasket on the outer lid. It tends to hold the water during the cooking cycle. Be sure to wipe dry every use. Otherwise, water/dew may drip into inner pan and cause lifting.</li> </ul>
<p>The non-stick coating may begin to deteriorate. The coating won't melt in food even if you eat the coating flake, which is non-toxic and would pass through the body without being absorbed.</p>
<ul> <li>Plug in to power source</li> <li>Press and hold [Cancel] button for 5 second.</li> <li>Make sure no lights is on.</li> <li>Note: Unplugging the power cord does not reset cooking function.</li> </ul>
<p>No, we do not recommend using milk. Normally milk shoot out from the vent.</p>
<p>Yes. You may use use COLD broth for your rice. Please select [Mix rice] menu setting. Maximum cooking amount is 60% of capacity. 10 cup rice cooker is 6 cup 5.5 cup rice cooker is 3 cup.<br /> Note: Do not use tomato sauce. Consistancy of tomato sauce is too thick for rice cooker. Rice result is under cook.<br /> Note: JNP and JAZ models are not applied to this subject.</p>
<ul> <li>That is minimum amount of rice can be cooked in the rice cooker.</li> </ul> <p>          - 5.5 cup rice cooker is 1 cup</p> <p>          - 10 cup micro-computer rice cooker is 2 cup </p> <p>          - JNP-1500 and 1800 are 3 cups.</p> <ul> <li>Rice cooker is design to cook perfect rice. If you are cooking below the minimum amount, heat does conduct properly and it lead to early shut off.</li> </ul>
<p>We do not recommend using alkaline balance over PH9. Alkaline water breakdown rice starch and rice result is wet or sticky. High alkaline water change color of rice to yellow.</p>
<p>No. Liquid temperatures above 35°Cor 95°F lead to malfunction.Temperature sensor does not work properly so that rice does not cook thoroughly. Be sure to use cold water.</p>
<p>No. Rice cooker need to cool off before start second batch. (Remove inner pan and open the lid. Let it stand at least 30 minutes to 60 minutes depending on surrounding room temperature). For the second batch,be sure to use cold water/ broth. If you add temperature above 35°C/95°F, Sensor does not work properly. Usually rice result is under cook.</p> <p>Do not insert second batch/ inner pan into cooker while the rice cooker is cooling off. Remaining heat conduct to inner pan and temperture may reach above 35°C/95°F.</p>
<p>Repair or unit does not work properly, contact customer service.</p>
<ul> <li>Did you use Keep warm function longer than 24 hours ?</li> <li>Keep warm time flash after 24 hours elapsed.</li> <li>We recommend removing remain rice into different container.</li> </ul>
<p>[Bad Smell]<br /> Normally the bad smell comes from bacteria multiplication. Uncooked rice frequently contains bacteria called Bacillus cereus which can be found in soil. These spore-forming bacteria can survive cooking process and protective spore can germinate, grow and produce toxin, if rice cooled off slowly or improper storing. Reheating cooked rice does not inactivate the toxin or kill bacteria cell. Unfortunately contaminated cooked rice is not visible, taste or smell or any different to normal rice.</p> <p>It is common for food producers to prepare large quantities of rice and kept in rice cooker for extended time. Heating can activate spores, which allow them to germinate and grow under warm and moist conditions. Very few people realized that cooked rice can be responsible for their food-born illness. Cooked rice must be kept above 140°F or cool rice as quickly as possible in different container and then stored below 39°F to minimize growth and toxin formation.</p> <p>Unluckily, once rice cooker is starts to smell, bacteria is already outgrow, it is not safe to eat at this point. Since Bacillus cereus can not kill in boiling water, please follow this cleaning guide below:</p> <ol> <li>Remove inner pan, inner lid steam vent cap, gaskets, dew collector, spatula holder.</li> <li>Make sanitizing solution: 2 tbsp of Chlorine bleach, 2 tbsp of dish soap and hot/boiling water</li> <li>Soak removable parts for 2-3 hours</li> <li>Rinse well</li> <li>Dry off with dry cloth</li> </ol> <ul> <li>Did you wash the rice thoroughly?</li> </ul> <ul> <li>Remove rice bran by washing. Remaining rice bran may smell,change color.</li> </ul> <ul> <li>Did you set the timer for longer than 12 hours?</li> </ul> <ul> <li>When the surrounding temperature is high, sometime water and uncooked rice become spoiled.
