2. Sigurnosne informacije

Please read and understand all safety instructions before operating the device. Failure to comply with these instructions may result in electric shock, fire, or damage to the product.

• Uvijek spojite napajanje na uzemljenu utičnicu.
• Nemojte raditi na mokrom ili damp uvjetima.
• Osigurajte odgovarajuću ventilaciju kako biste spriječili pregrijavanje. Ne blokirajte otvore za zrak.
• Ne otvarajte casing; unutra nema dijelova koje korisnik može sam servisirati. Servisiranje prepustite kvalificiranom osoblju.
• Provjerite unos voltage settings (110V/220V) match your local power supply before connecting.
• Use only the specified power cord and accessories.
• Isključite napajanje prije bilo kakvog spajanja ili odspajanja na izlaznim terminalima.
