6.2 Format Memory

To format the memory, connect the recorder to your computer. Select "FAT32" low-level formatting for Windows 2000 or above. For Mac users, select "formatted removable disk" or "Clean-up".

7. Troubleshooting

Q: The storage capacity displayed in the device is not the same as the nominal value?

A: Computers use binary calculations (1KB = 1024 bytes, 1MB = 1024KB, 1GB = 1024MB). Additionally, internal firmware and system files occupy a small amount of memory space, leading to a difference between identified and actual usable memory.

Q: Some songs cannot be played on this device?

A: Please check if the music format is correct. Ensure the files are in supported formats (MP3/WAV).

Q: Why does this recorder react slowly?

A: Frequent use and deletion can lead to flash memory fragmentation (similar to a hard disk). If this occurs, please format the flash memory. Also, check if the MP3 files themselves are damaged.
