Solution
• Turn up the volume (on your external
device or speaker).
• In LINE IN mode, check that the cable
is securely connected and the external
device is working properly.
• When using the microphone, check the
cable, then make sure the microphone
is switched on and its volume is enabled
on the speaker.
• In USB or TF mode, check that there
are compatible files on the stick or
card and that they are not corrupted.
Try reloading the files onto the media
device or use another USB stick or TF
card.
