More details will be written later. The SONY ICD-SX400 is a voice recorder with a silver body that allows for high-quality audio recording. There is no cable to connect the main unit to a computer. I think it's the same as Sony digital cameras, etc. I had the instruction manual somewhere, so I will look for it, but it might not be there. - Brand: SONY - Model: ICD-SX20 - Color: Silver - Function: Voice Recorder Thank you for viewing.
