Hałaśliwe odtwarzanie	Spróbuj z innymi piosenkami. Specyfikacje utworów nie są obsługiwane przez to urządzenie. Jeśli szum pojawia się tylko podczas odtwarzania DSD files, check and adjust the computer system volume, music player volume, and driver volume to the maximum. Sprawdź, czy problem leży w źródle, urządzeniach podłączonych do sieci i kablach. If the noise disappears after unplugging the USB cable, it may be interference from the source. Consider using a USB isolation device between this unit and the source.
Jeden kanał z szumem/brak wyjścia	Check to see if the problem is with the source, downstream equipment, and cables. Try swapping the left and right channel connections and test with another source.
Nierównowaga kanału	Check to see if the problem is with the source, downstream equipment, and cables. Try swapping the left and right channel connections and test with another source.
Nie można sparować Bluetooth	Enable Bluetooth function in the setup menu first. May be already connected to another Bluetooth device. Press and hold the brightness button in the lower right corner on the remote to let this unit enter pairing mode. Zbliż urządzenie Bluetooth do tego urządzenia. Turn the power of the unit off and on again, and then try again.

To prevent electromagnetic interference, locate this unit away from microwave ovens, wireless LAN devices, and other Bluetooth devices. Ponownie podłącz urządzenie Bluetooth.
Podłączone urządzenie USB nie rozpoznaje tego urządzenia	USB cable did not connect properly. Check or change the cable. Spróbuj użyć innego portu USB. Driver may need to be reinstalled. Przyczyną może być komputer. Sprawdź lub spróbuj na innym komputerze. Niektóre telefony wymagają najpierw włączenia funkcji OTG.
Pilot nie odpowiada	Spróbuj włożyć dwie nowe baterie AAA. Proszę kierować pilota w stronę odbiornika. Zbliż pilota do urządzenia. Za pomocą kamery w telefonie z systemem Android spójrz na nadajnik znajdujący się w górnej części pilota. Jeżeli nie miga on po naciśnięciu przycisku pilota, oznacza to, że pilot jest uszkodzony.

Because some players can't be set to exclusive mode, the audio signal will be resampled by the computer/phone and then output.
