Problem
Cannot find a MP3 file.
Sometimes the options of setup
menu cannot be selected.
Tip
Make sure that the selected folder does not contain more
than 2,000 files .
Make sure that the file extension is .mp3 or .MP3.
When playing a DVD disc, press STOP button once, the player
will go into stop resume mode, meanwhile you cannot change
some settings in setup menu such as language subitem
menu, audio, subtitle etc. If you want to change that, press
STOP button twice, the player will go into full stop mode,
then you can do it.
