Thank you for viewing! Infrared operation confirmed. I was using it until just now. I am selling the remote control because I disposed of the air conditioner. (2025.6.28) Cleaned with disinfectant wipes. Batteries are not included. Please purchase with the understanding that this is a used item. The fourth photo is the product information section of the air conditioner unit. I took the photo for reference. Wrapped in a single layer of bubble wrap and waterproofed with a plastic bag.
