I purchased this for meetings, but I never had the opportunity to use it. I only recorded for about a minute to test it, so I am putting it up for sale. The data has been initialized. This stereo IC recorder can record for 16 hours. It supports USB connection and is ideal for recording meetings and lectures. - Model: ICD-TX660 - Recording time: 16 hours - USB connection: Yes - Recording format: Stereo - Included features: Meeting/lecture recording Thank you for looking.
