After SAST listened to the radio loudspeakers will play u how to do it.
Contact manufacturers to understand later, my song is damaged, followed by the first point of the way to re import, and then solved. The playback effect is pretty good, occasionally using a mobile phone is connected with the speaker AUX Jack sing, more convenient.
I use the winning E188M, also use U disk to sing a song, always motionless.
