To use a small Aroma rice cooker, follow these steps:

1. Measure the rice using the rice measuring scoop that comes with the cooker (this scoop measures about ¾ of a traditional cup). For small amounts, start with about 1 scoop (150g rice).
2. Rinse the rice in a strainer under cold water until the water runs clear to remove excess starch.
3. Place the rinsed rice in the inner cooking pot of the rice cooker.
4. Add water according to the rice-to-water ratio recommended for small quantities. For Aroma rice cookers, the typical ratio is about 1:1.33 rice to water by volume. For example, for 1 scoop of rice, fill water to the corresponding inner pot line (line 1) or add about 1 1/3 scoops of water (around 236ml or 8 fl. oz.).
5. Push down any rice on the edges to ensure even cooking.
6. Place the lid securely on the rice cooker.
7. Plug in the rice cooker and press down the cook switch/button to start cooking. The cook light will illuminate.
8. When cooking is complete, the cooker will switch to the "keep warm" mode automatically. Let the rice sit for about 10 minutes with the lid closed to absorb remaining moisture.
9. Open the lid and fluff the rice with a rice paddle before serving.

For very small portions (like less than half a cup of dry rice), note that rice may stick to the bottom. Letting the cooker sit unplugged for 5-10 minutes after cooking can help soften the bottom rice. Using a stainless steel inner pot tends to reduce sticking as well. The cooker is simple to operate and can cook as little as 1 scoop of rice, making it suitable for small servings.

If the rice cooker has additional buttons, like "white rice" or "brown rice," use the appropriate setting for the type of rice being cooked. For basic models, the on/off or cook switch is the main control.
