AT TENZIONE

RISCHIO DI SCOSSE 

ELETTRICHE, NON APRIRE 

ATTENZIONE: PER RIDURRE IL RISCHIO DI SCOSSE 
ELETTRICHE, NON TENTARE DI APRIRE ALCUNA PARTE 

DELL’UNITÀ. NON CI SONO PARTI INTERNE AD USO DELL’UTENTE. 
RIVOLGERSI A PERSONALE QUALIFICATO PER L’ASSISTENZA.

NON ESPORRE QUESTO APPARECCHIO ALLA PIOGGIA, 
UMIDITÀ O SOSTANZE LIQUIDE. OGGETTI PIENI DI LIQUIDI, 

COME VASI, NON DEVONO ESSERE COLLOCATI SU QUESTO APPARATO.

I TERMINALI DEI DIFFUSORI POTREBBERO ESSERE 
PERICOLOSI, SE VIENE UTILIZZATA LA CONNESSIONE IN 

MODALITÀ BRIDGE DEGLI ALTOPARLANTI.

ADOTTARE LE CORRETTE TECNICHE DI CONNESSIONE E 
ISOLAMENTO QUANDO VIENE UTILIZZATA LA CONNESSIONE 

IN MODALITÀ BRIDGE DEGLI ALTOPARLANTI.

SPIEGAZIONE DEI SIMBOLI GRAFICI

Il triangolo con il lampo è utilizzato per avvisare 
l’utente del rischio di scossa elettrica.

Il triangolo con il punto esclamativo è utilizzato per 
avvisare l’utente di importanti istruzioni d’uso e ma-
nutenzione.

Il marchio CE indica la conformita’ del prodotto a 
tutte le direttive europee applicabili

Simbolo della connessione di terra.

Simbolo di conformità alla Direttiva 2002/96/CE e 
alla Direttiva  2003/108/CE del Parlamento Europeo 
sulle apparecchiature elettriche ed elettroniche 
(RAEE).

Simbolo per le apparecchiature sensibili alle scariche 
elettrostatiche

Questo modulo amplificatore è destinato ad essere 

installato dentro altri dispositivi e deve quindi 

essere controllato nel prodotto finito.
