2. What should I do if the Micro SD card can not work?
(1) Ensure that the Micro SD card is in good condition. Also check that the audio files
are the correct formats - MP3/WMA/WAV/APE/FLAC.
(2) Besides the above case, the problem maybe the compatibility of the Micro SD card.
We recommend you formatting the Micro SD Card to FAT32 file formats.
