MP3 Player Instructions for Tecsun PL398BT


I recently purchased a Tecsun PL398BT radio (from HK Supplier ANON)  which came with a free Mini MP3 Player.  Unfortunately no instructions or info were included about how to operate this MP3 Player.  Does anyone know where instructions can be found for the use of this Mini Tecsun MP3 player, and whether it can even be used with the PL398 Radio?  Any replies would be very much appreciated.
