Where can you get a replacement measuring cup for aroma rice cooker?

From aromaco.com.AromaI have a Aroma measuring cup but have lost the instructions. The cup measures 180 ml as per the information below:

Each rice cooker typically comes with the cup that should be used for measuring rice for that particular cooker. The graduations on the bowl for adding water rely on using that particular measuring cup. The rice cooker cups can vary in size, but are typically 180 ml, which is the size of a traditional Japanese cup (gō). Note that this cup is not the same size as the customary 8 fl oz cup (about 237 ml) which is used for cooking in the United States.

If this helps, please send me the water to rice ratio to will@packlinewest.com
