17. Troubleshooting
By purchasing this device, you have acquired a product designed to the state of the art and operationally
reliable. Nevertheless, problems or errors may occur.
The following contains descriptions for the removal of possible interferences.
Always observe the safety information.
No sound is audible:
• A device of the playback chain is not activated (e.g. CD player).
• The wrong input has been chosen at the receiver or the cables are connected incorrectly.
• The receiver volume is set to a minimum.
• Muting is activated at the receiver (mute).
• The button „EQUALIZER" on the receiver (M) or the IR remote control (3) has been pushed to use an
external equalizer. However, it is not connected or not switched on.

One channel does not work:
• A cinch cable has come loose from the receiver or the connected device or the cable is defective.

MP3 files from the USB data carrier are not played:
