ONKYO RC-734S remote control. This item has been in long-term home storage and was found during a closet clean-up. Since I don't have the main unit, I've tested its functionality using infrared light. Batteries are not included. I am not familiar with the technical aspects of these devices, so I cannot answer questions about compatible models. Thank you for your understanding. If there are any issues upon arrival, I will address them, so please feel confident in your purchase. The item has been cleaned with electrolytic water and anhydrous alcohol around the time of listing. Please refer to the photos for the detailed condition. This is a used item. Please understand that it is a pre-owned item before purchasing.
