Why can’t I play some MP3 files?
The MP3 file has to be compressed along some standards like MPEG1/MPEG2/MPEG 2.5 layer 3. Otherwise, the file must be converted using a software application.
The remote control does not work properly.
Use the remote while pointing it directly to the player and without obstacles in between. Also make sure the batteries are not depleted.
What's the playback time of the player?
The autonomy depends greatly in the playback conditions. You can have up to 2 hours of music playback.
