Lost measurements for rice/water ratio?

Hello, Thank you for contacting us with your question on the ARC-914S. When cooking rice you do want to use the cup provided to measure the rice. Should you want to cook 1 cup or rice you would fill cup up to brim, add to inner pot, rinse rice, then fill to corresponding water line 1 cup. We do have manuals available to download on our web site www.aromaco.com. Should you have any other questions or concerns please feel free to contact me at customerservice@aromaco.com or call at 1-800-276-6286 ext. 1 M-F 8:30AM-4:30PM PST. You can ask to speak to me directly or any one of our knowledgeable representatives would be more than happy to assist as well. Kind Regards, Anthony Macalintal Aroma Housewares Customer Support Specialist
