4. Setup
Before first use, follow these steps:
- Unpack: Carefully remove the rice cooker and all accessories from the packaging. Retain packaging for future transport or storage.

5. Operating Instructions
Follow these steps for cooking rice:
- Measure Rice: Use the provided measuring cup to measure the desired amount of rice. One cup of uncooked rice typically yields about 2-3 cups of cooked rice.
- Wash Rice: Wash the rice thoroughly in a separate bowl until the water runs clear. This removes excess starch.
- Add Rice to Inner Pot: Place the washed rice into the inner pot.
- Add Water: Add water to the corresponding water level mark inside the inner pot. For example, if you added 3 cups of rice, fill water to the "3" mark for white rice. Adjust water levels according to your preference for softer or firmer rice.
- Wipe Pot Exterior: Ensure the exterior of the inner pot is dry before placing it into the main unit.
- Place Inner Pot: Carefully place the inner pot into the main unit, ensuring it sits correctly.
- Close Lid: Close the outer lid securely until it clicks into place.
- Select Menu: Plug in the power cord. Use the menu buttons to select your desired cooking setting (e.g., White Rice, Brown Rice, Quick Cook).
- Start Cooking: Press the "Start" button. The cooking indicator light will illuminate.
- Completion: Once cooking is complete, the rice cooker will typically switch to a "Keep Warm" mode automatically. Allow the rice to steam for an additional 5-10 minutes in Keep Warm mode for best results before serving.
- Serve: Use the provided rice scoop to fluff and serve the rice.
- Unplug: Unplug the rice cooker from the power outlet after serving and when not in use.
6. Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your rice cooker. Always unplug the unit and allow it to cool completely before cleaning.
Daily Cleaning (Inner Pot and Inner Lid)
- Inner Pot: Wash the inner pot with warm soapy water using a soft sponge. Do not use abrasive cleaners or metal scrubbers, as this can damage the non-stick coating. Rinse thoroughly and dry completely.
- Inner Lid: Remove the inner lid from the main unit. Wash it with warm soapy water. The inner lid is also dishwasher safe for convenient cleaning. Rinse thoroughly and dry completely before reattaching.
