Sostituzione del fusibile

Se un altro apparecchio elettrico funziona una volta collegato alla presa di rete, ma la spia di Standby continua a non illuminarsi quando l’RA-04 è collegato alla presa di rete e viene premuto il tasto Power, significa che potrebbe essersi bruciato il fusibile di protezione interno. Se ritenete che ciò possa essere successo, con- tattate il vostro rivenditore Rotel per indicazioni sulla sostituzione del fusibile.

Nessun suono

Controllate la sorgente di segnale per verificare che stia funzionando correttamente. Assicuratevi che i cavi dalla sorgente di segnale agli ingressi dell’RA-04 siano collegati correttamente. Verificate che il selettore Listening sia posizionato sull’ingresso corretto. Controllate tutti i cavi di collegamento tra l’RA-04 ed i diffusori.
