No Power, No Lights
The standby switch is used to turn the unit on. Make sure this switch has been pressed.
Make sure mains power switch is on at the wall.
Check the supplied plugpack is connected correctly.
MP3 files not playing
The files must be MP3 format. Not wav, AAC or other.
Check SD card is inserted correctly.
DIP switch changes not effective
Turn the unit OFF before changing DIP switch settings. Settings become effective after power is returned.
