Instruction of U disk MP3 encoding playing

When you need to use the built-in MP3 encoding function, please format your USD disk (U disk for short below) as FA-T32 format in computer first and then copy the file in MP3 format in U disk. When reading U disk, the encoding system will engage in encoding playing according to the generation sequence of MP3 songs file. Therefore, the song which is copied to U disk first will be played in priority or vice versa. When the user needs to play according to the specific sequence, they can arrange the copying sequence. If the files copied to U disk can not be played, please inspect whether the file format is in MP3 format. If not, please switch to MP3 format in computer and then copy to U disk in order to play normally. When copying MP3 file, you shall copy to the catalogue of U disk. It is suggested to delete all the unnecessary files and file catalogues in order to reduce the occurrence of reading error when the encoding is played. When the user buys U disk, please select the ones with better quality and internal encoding supporting 64MB/128MB/256MB/512MB/1GB/2GB/4GB/8GB and other volumes. During the playing process, please make it far away from the places with high temperature, high magnetic field and high frequency interference. In case of crash, please close the power and restart for recovery!
