insert the card as shown in the diagram on the

Flash Card Programming Guide
A CompactFlash card reader is required for programming. Format the
flash card with the FAT file system (not FAT32). Copy the sound files into
the root directory (top folder) on the flash card, and then add a unique,
three digit track number at the beginning of each filename such as “001
original name.mp3”. Track numbers should be within 001 to 099.
