・ This is the RC-633S remote control for ONKYO's FR-UN9/FR-UN7/X-UN9/X-UN7. ・ I have confirmed that infrared light is emitted from all buttons. ・ It has been cleaned and is free of dirt, but as it is a used item, there may be scratches and minor imperfections. There are no major scratches. The inside of the battery box is free of any signs of battery leakage, and I think it has relatively little sun damage. ・ Please prepare two separate AA batteries. As I am also listing this on other sites, please comment before purchasing. Thank you for your cooperation.
