SHARP Remote control for CD radio cassette QT-K3 As shown in the photos, infrared emission has been confirmed for all buttons. Since I don't have the radio cassette player itself, I cannot confirm direct operation with the radio. Please consider purchasing with this in mind. There is no battery leakage in the battery case. There is some minor dirt, but no noticeable scratches. Uses 2 AA batteries. Batteries are not included. Thank you. #Sharp #SHARP
