ONKYO ONKYO Genuine Remote Control Model Number: RC-402C This is the genuine remote control for the full-size CD player C-724AX, but it can also operate C-705FX2, C-705TX, and other models. It seems to be compatible with many models as a substitute for ONKYO's general-purpose CD player remote control "RC-289C". It can be used independently without connecting to the RI terminal. I actually connected it to a C-705FX2 and was able to use the main operations. The tray also opens with the remote control, and the power turns on. There are no scratches or liquid leakage marks on the case. Uses 2 AA batteries (batteries sold separately) Free shipping and anonymous delivery. Immediate purchase without comments is OK. Thank you. - Model: RC-402C - Brand: ONKYO - Remote Control Type: For audio equipment - Functions: Tray open, play, stop, skip, shuffle, repeat, etc. Thank you for viewing.
