This is a used item. I believe it was working normally, but I haven't been able to confirm its operation. It comes with a remote control. I'm not very knowledgeable about this, so I may not be able to answer detailed questions. Please refer to the photos for your assessment. Both the main unit and the remote control have scratches and stains, so it might be good for parts. The remote control is discolored. Please understand that this is a used item with scratches, stains, discoloration, and unconfirmed operation before purchasing. Please read my profile before purchasing!
