4. Operating Instructions
4.1. Cooking Rice
- Measure Rice: Use the provided measuring cup to measure the desired amount of rice. Do not overfill.
- Wash Rice: Rinse the rice thoroughly under cold water until the water runs clear. This removes excess starch.
- Add Water: Place the washed rice into the inner cooking pan. Add water according to the water level marks inside the pan, corresponding to the amount of rice and desired rice type (e.g., white rice, brown rice). Refer to the cooking chart in the full manual for precise water ratios.
- Place Pan: Place the inner cooking pan into the main body of the rice cooker, ensuring it sits properly. Close the outer lid securely.
- Select Menu: Press the "Menu" button to select the desired cooking menu (e.g., White Rice, Brown Rice, Sushi Rice, Quick Cooking, Cook Aging).
- Start Cooking: Press the "Start" button. The cooking indicator light will illuminate, and the cooking process will begin.
- Completion: Once cooking is complete, the rice cooker will typically switch to "Keep Warm" mode automatically. An audible signal may sound.
- Serve: Open the lid, gently fluff the rice with the provided spatula, and serve.
4.2. Keep Warm Function
The rice cooker automatically switches to "Keep Warm" mode after cooking. This function maintains the rice at an optimal serving temperature without drying it out. The "Keep Warm" function can typically be maintained for several hours (up to 24 hours as noted in some user experiences) without significant degradation of rice quality.
4.3. Timer Function
The timer function allows you to set a specific time for the rice to be ready. This is convenient for preparing rice in advance.
- Prepare rice and water in the inner pan as usual.
- Press the "Timer" button.
- Use the arrow buttons to adjust the desired completion time.
- Press "Start" to activate the timer. The rice cooker will calculate the cooking start time to ensure rice is ready at the set time.
5. Cleaning and Maintenance
Regular cleaning ensures the longevity and hygienic operation of your rice cooker. Always unplug the unit and allow it to cool completely before cleaning.
- Inner Cooking Pan: Wash with warm, soapy water using a soft sponge. Do not use abrasive cleaners or metal scrubbers, as this can damage the non-stick coating.
- Inner Lid: Remove the inner lid and wash it with warm, soapy water. The "Clear Coat Lid" and "Stainless Lid" are designed for easy cleaning.
- Steam Vent Cap: Remove and clean the steam vent cap to prevent clogs.
- Exterior: Wipe the exterior of the main unit with a soft, damp cloth. Do not use harsh chemicals or immerse the unit in water.
