La logica di selezione ed incremento per il ricevitore è la seguente:
- Tenendo premuto SET per qualche secondo si possono selezionare i parametri modicabili.
- Il primo parametro, secondo una sequenza preordinata, inizia a lampeggiare.
- Utilizzando le relative frecce SU/GIU del ricevitore si aumenta/diminuisce (oppure si seleziona ON/OFF, a seconda
del parametro) il valore in oggetto.
- E’ possibile uscire dalla sequenza premendo il tasto ESC, oppure continuare a modicare parametri.
Una rapida visualizzazione dei parametri visualizzati nei display del trasmettitore e del ricevitore è illustrata qui

PROBLEMA POSSIBILE SOLUZIONE
Il ricevitore non si accende • Vericare la presenza di alimentazione a monte
dell’impianto, la corretta connessione dei cablag-
gi, e ripetere la procedura di accensione.
Il trasmettitore non si accende • Vericare l’inserimento e la carica delle batterie,
eventualmente sostituirle. Ripetere la procedura
di accensione.
Il segnale audio non arriva al mixer • Vericare i cablaggi ed il livello di input sul ricev-
itore. Eventualmente ripetere la procedura di
sincronizzazione.
