SONY Remote Control RM-S317 Although I haven't been able to confirm operation with the actual device, I have confirmed that infrared rays are emitted by all the buttons (see photos). However, I don't know if all the buttons will work properly on the actual device, so please understand and acknowledge that this item may have operational defects before considering purchasing. This is an auction for the remote control itself only; items not shown in the photos are not included. Please be aware of this. Due to being a used item, there is rust and dirt in the battery compartment (see photos), and there are some scratches on the remote control body. Please refrain from purchasing if you are a nervous person, as this is a used item. For home appliances, I test the operation of items that can be tested before listing them (items with unconfirmed operation are noted), but I do not guarantee their operation, so please understand and acknowledge this before considering purchasing. Also, to prevent swapping, we cannot accept returns or refunds after purchase, so please also be aware of this. Please be sure to check and understand the above conditions before purchasing.
