Note: Continuous playback time was tested after playback by locking the hold switch and putting the LCD to sleep, and then leaving it untouched. This was done to eliminate human operation and confirm the average performance of the purchased battery group. This is not based on actual use. In reality, the playback time will be considerably shorter due to power consumption by the LCD each time you operate it, change songs, adjust the volume, etc. In that case, it seems that the playback time will be longer if you minimize the LCD brightness. Note: All units are initialized in iTunes, songs are loaded, operation is confirmed, and only normal units are finally initialized and shipped. There is no audio noise. Used, working product. This is an auction for the main unit only. Battery replaced with a new one (2025/12/16) LCD has not been replaced. It displays normally. Click wheel sw assy replaced with a new one.
