This is a compatible remote control for Sharp recorders. After purchase, I recorded using an external HDD connected to the TV, so I ended up not using this remote, making it a new and unused item. I opened it for the photos and have confirmed that the power on, play, and program display functions work. Batteries are not included. ● The following is a description from the purchase site [excerpt] (please refer to it): 1.
