Nema zvuka	Uređaj se nije uključio. Provjerite napajanje. Provjerite je li odabran odgovarajući ulazni izvor. Pritisnite gumb na prednjoj ploči za promjenu ulaznog kanala. Provjerite postavku izlaza. Provjerite veze za sve uređaje. Umetnite priključne kabele do kraja. Provjerite glasnoću svih uređaja i jesu li isključeni. Bluetooth IN: Preniska glasnoća na telefonu. Prilagodite glasnoću. USB ULAZ: 1) Too low volume on PC. Please check and adjust the computer system volume, music player volume and driver volume to the maximum. 2) Select the default output device of your music player or computer as this unit.
Šumna reprodukcija	Pokušajte s drugim pjesmama. Ovaj uređaj ne podržava specifikacije pjesama. Ako se šum pojavljuje samo prilikom reprodukcije DSD-a files, please check and adjust the computer system volume, music player volume and driver volume to the maximum. Provjerite je li problem u izvoru, nizvodnoj opremi i kabelima. Ako šum nestane nakon isključivanja USB kabela, moguće je da je riječ o smetnjama iz izvora. Možete pokušati dodati USB izolaciju između ovog uređaja i izvora.
One channel with noise / no output	Provjerite je li problem u izvoru, nizvodnoj opremi i kabelima.
Neravnoteža kanala	Set to C (Balance) in [Setup Menu - Advance - Channel balance]. Provjerite je li problem u izvoru, nizvodnoj opremi i kabelima. You can try swapping the left and right channel connections and try with another source.
Cannot pair the Bluetooth	Prvo omogućite Bluetooth funkciju u izborniku postavki. May be already connected to another Bluetooth device. Press and hold headphone button on the remote control to let this unit enter pairing mode. Približite Bluetooth uređaj ovoj jedinici. Turn the power of the unit off and then try again. Približite Bluetooth uređaj ovoj jedinici. Uklonite prepreke između Bluetooth uređaja i ove jedinice.
Bluetooth ulaz: zvuk je isključen	Kako biste spriječili elektromagnetske smetnje, postavite ovu jedinicu dalje od mikrovalnih pećnica, bežičnih LAN uređaja i drugih Bluetooth uređaja. Ponovno povežite Bluetooth uređaj.
Priključeni USB uređaj ne prepoznaje ovaj uređaj	USB kabel nije ispravno spojen. Provjerite ili promijenite kabel. Problem s upravljačkim programom. Pokušajte ponovno instalirati upravljački program. Maybe caused by the PC. Check or try with another PC. Neki telefoni zahtijevaju da prvo bude omogućena OTG funkcija.
Daljinski upravljač ne reagira	Prvo omogućite funkciju daljinskog upravljanja u izborniku postavki. Pokušajte umetnuti dvije nove AAA baterije. Molimo usmjerite prema prijemniku daljinskog upravljača. Približite daljinski upravljač uređaju. Pomoću kamere svog Android telefona pogledajte odašiljač na vrhu daljinskog upravljača. Ako ne treperi kada pritisnete gumb na daljinskom upravljaču, daljinski upravljač je neispravan. Ako imate više od jednog uređaja za prelijevanje, provjerite koristite li ispravan daljinski upravljač.
Ne mogu podesiti glasnoću ovog uređaja	Please check if DAC mode was set in [Setup menu-Advanced-DAC mode]. In DAC mode, the volume is not adjustable and is the maximum value, while in PRE mode the volume can be adjusted. Set it to PRE mode if you need to adjust the volume.
SampBrzina zvuka prikazana na uređaju ne odgovara glazbi file	The choice of music player app, the setting of music player and the setting of computer/phone will all have an impact on the sampling stopa. SampBrzina linga koju prikazuje ova jedinica je sampbrzina prijenosa ulaznog signala i neće promijeniti sampsama stopa linga. If the music player can be set to exclusive mode, the audio signal will not be resampvođen računalom/telefonom, pa sampBrzina prijenosa izlaznog signala je sampstopa linga originala file, i sampBrzina linga koju prikazuje ova jedinica također je sampstopa linga originala file. Budući da se neki playeri ne mogu postaviti na ekskluzivni način rada, audio signal će biti...ampvođen računalom/telefonom, a zatim izlaz. Dakle, ovaj uređaj će uvijek prikazivati sampbrzina poziva koju postavlja računalo/telefon. We recommend using Audirvana player on MAC OS and Foobar on Windows.
