SONY personal audio system with CD, cassette, and radio functions. - Brand: SONY - Model: CSD-S401 - Functions: CD, cassette, radio - Color: Black - Operation buttons: Play, Stop, Fast Forward, Rewind, Snooze - System type: Personal audio system Thank you for viewing. Made in 20 years ago (likely referring to the year 2000 or 2001). When listening to CDs, the sound sometimes repeats, and the repair estimate was quite expensive, so I replaced it. SONY products look great as interior decorations, and it's not completely unusable. It might be possible to use it for parts. I think there will be no problems if you consider it as an interior item rather than a practical one. The warranty period has expired, and there are no instructions. Please refrain from purchasing if you are expecting it to be a practical item. Please treat this as a junk item. The main unit is generally in good condition.
