Manuale Istruzioni User Manual IT Prima di fissare il prodotto verifica il giusto allog- giamento sulla tua chitarra; appoggia centralina e strip led (senza rimuovere la protezione dell’adesi- vo) e trova la giusta posizione per applicarli. Segui questo passaggio solo se devi installare il prodotto. IT A Rimuovi la protezione dell’adesivo posto sotto la centralina e fissala tenendo aderente il supporto della strip led (A) alla chitarra. Rimuovere protezione adesivo Segui questo passaggio solo se devi installare il prodotto. IT Scollega il cavo dalla centralina e bloccalo sulla chitarra utilizzando il mattoncino adesivizzato. Ricollega il cavo alla centralina. Rimuovere protezione adesivo Segui questo passaggio solo se devi installare il prodotto. IT LED SULLA CENTRALINA Rosso > spento in carica Verde > acceso Arancione > acceso in carica Blu > connesso Viola > connesso in carica ACCENSIONE Per accendere il dispositivo tieni premuto il tasto di accensione indicato per almeno 2 secondi. Per spegnere il dispositivo premi il tasto. IT RIMOZIONE CENTRALINA Prima di rimuovere la centralina dalla base di anco- raggio, scollega delicatamente il cavo di collega- mento della strip led. Tieni premuta la linguetta (A) e fai scorrere la centralina lungo il verso della freccia mostrata in figura. A IT RIAPPLICAZIONE CENTRALINA Allinea i 4 supporti della base di ancoraggio con i 4 fori sul fondo della centralina, fai scorrere leg- germente la centralina fino allo scatto di chiusura. IT ATTACCO DI RICARICA Il connettore magnetico applicato alla centralina è rimovibile per consentirti di ricaricare anche con un normale cavo micro usb. IT Ciao e benvenuto nel mondo Visual Note, vogliamo darti qualche consiglio per sfruttare al meglio il di- spositivo e l’App fin da subito. Innanzitutto se devi installare Visual Note sulla tua chitarra segui le istruzioni qui di seguito ricordandoti di maneggiare con cura e delicatezza la strip led: VIDEO INSTALLAZIONE PRODOTTO www.visual-note.com/it/setup SCARICA L’APP Visual Note dal tuo store (Google Play o App Store) IT CONNESSIONE BLUETOOTH PROCEDURA DI PRIMO ACCOPPIAMENTO: premi il simbolo del Bluetooth nell’App, poi premi “connetti” ed attendi che il dispositivo si connetta automaticamente. CONNESSIONE: quando il dispositivo è collegato all’App, il led sulla centralina e la prima fila di led sulla strip sa- ranno attivi e di colore blu. BASE DI ANCORAGGIO DELLA CENTRALINA: puoi facil- mente sganciare la centralina per ricaricarla o sosti- tuirla con una già carica. APPENDERE LA CHITARRA: quando usi un portachitarra con aggancio alla paletta controlla sempre che non interferisca con la centralina montata sul retro della paletta stessa. IT BATTERIA/RICARICA: nella confezione viene fornito un cavo USB di ricarica con ancoraggio magnetico di sicurezza. Collegalo ad un caricabatterie ed il led sulla centra- lina diventerà rosso, quando si spegnerà la luce la ricarica sarà completa. Dopo 5 minuti in stand by senza connessione blue- tooth, il dispositivo si spegne automaticamente. DURATA BATTERIA: 10h TEMPO RICARICA: 2/3h NB: prima della messa in funzione del dispositivo, lasciare in carica per un tempo minimo di 8 ore. EN Before applying the product, check if it fits cor- rectly on your guitar; place the control unit and LED strip (without removing the adhesive protection) and find the correct mounting position. Follow this step only if you need to install the product. EN A Remove the protective adhesive under the control unit and apply it while keeping the LED strip support (A) adherent to the guitar. Follow this step only if you need to install the product. Remove protection adhesive EN Remove protection adhesive Disconnect the cable from the control unit and lock it to the guitar using the adhesive brick. Re- connect the cable to the control unit. Follow this step only if you need to install the product. EN POWER ON To turn it on, hold down the button for at least 2 seconds. To turn it off, press the button. LED ON THE CONTROL UNIT: Red > turned off under charge Green > on Orange > on under charge Blue > connected Violet > connected under charge EN A CONTROL UNIT REMOVAL Before removing the control unit from the control unit support, gently disconnect the LED strip con- nection cable. Press the lever (A) and hold it down while sliding the control unit from its support in the direction of the arrow shown in the figure. EN CONTROL UNIT RE-APPLICATION Align the four supports of the anchor base with the holes on the control unit bottom and slide the unit slightly until it clicks. EN CHARGING CONNECTION The magnetic connector attached to the control unit is removable to allow you to charge even with a normal micro usb cable. EN Hi and welcome to the Visual Note world, we want to give you some advice to take full advantage of the device and the App from the start. First of all, if you have to install Visual Note on your guitar, follow the instructions below and remem- ber to handle the LED strip carefully: PRODUCT INSTALLATION VIDEO www.visual-note.com/en/setup DOWNLOAD THE APP Visual Note from your store (Google Play or App Store) EN CONTROL UNIT SUPPORT: you can easily remove the control unit to recharge it or substitute it with an already charged one. HANGING UP THE GUITAR: when you use a guitar hold- er with a hookup on the headstock, always check that it doesn’t interfere with the control unit mount- ed on the back of the same headstock. BLUETOOTH CONNECTION FIRST PAIRING PROCEDURE: press the Bluetooth logo in the App, then press “connect” and wait for the device to connect automatically.
