z UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size)
: LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher
than ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful!
Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.
Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

Se lautomobile dotata di antenna FM/MW/LW incorporata nel vetro posteriore/laterale, collegare il cavo (blu) di controllo dellantenna elettrica o il cavo (rosso) di ingresso dellalimentazione accessoria al terminale di alimentazione del preamplifi catore dellantenna esistente. Per ulteriori informazioni, consultare il proprio fornitore.
Non possibile usare unantenna elettrica senza scatola a rel con questo apparecchio.
Collegamento per la conservazione della memoriaQuando il cavo di ingresso alimentazione giallo collegato, viene sempre fornita alimentazione al circuito di memoria anche quando linterruttore di accensione spento.Note sul collegamento dei diffusori Prima di collegare i diffusori spegnere lapparecchio. Usare diffusori di impedenza compresa tra 4 e 8 ohm e con
capacit di potenza adeguata, altrimenti i diffusori potrebbero venire danneggiati.
Non collegare i terminali del sistema diffusori al telaio dellauto e non collegare i terminali del diffusore destro a quelli del diffusore sinistro.
Non collegare il cavo di terra di questo apparecchio al terminale negativo () del diffusore.
Non collegare i diffusori in parallelo. Assicurarsi di collegare soltanto diffusori passivi, poich
il collegamento di diffusori attivi, dotati di amplifi catori incorporati, ai terminali dei diffusori potrebbe danneggiare lapparecchio.
Per evitare problemi di funzionamento, non utilizzare i cavi dei diffusori incorporati installati nellautomobile se lapparecchio condivide un cavo comune negativo () per i diffusori destro e sinistro.
Non collegare fra loro i cavi dei diffusori dellapparecchio.Nota sui collegamentiSe lamplifi catore e il diffusore non sono collegati correttamente, Failure viene visualizzato nel display. In tal caso, accertarsi che lamplifi catore e il diffusore siano collegati correttamente.

WarningIf you have a power aerial without a relay box, connecting this unit with the supplied power connecting lead 3 may damage the aerial.Notes on the control power and suppy leads The power aerial control lead (blue) supplies +12 V DC when
you turn on the tuner, or when you activate the AF (Alternative Frequency) or TA (Traffi c Announcement) function.
When your car has built-in FM/MW/LW aerial in the rear/side glass, connect the power aerial control lead (blue) or the accessory power input lead (red) to the power terminal of the existing aerial booster. For details, consult your dealer.
A power aerial without a relay box cannot be used with this unit.
Memory hold connectionWhen the yellow power input lead is connected, power will always be supplied to the memory circuit even when the ignition switch is turned off.Notes on speaker connection Before connecting the speakers, turn the unit off. Use speakers with an impedance of 4 to 8 ohms, and with
adequate power handling capacities to avoid its damage. Do not connect the speaker terminals to the car chassis, or
connect the terminals of the right speakers with those of the left speaker.
Do not connect the earth lead of this unit to the negative () terminal of the speaker.
Do not attempt to connect the speakers in parallel. Connect only passive speakers. Connecting active speakers
(with built-in amplifi ers) to the speaker terminals may damage the unit.
To avoid a malfunction, do not use the built-in speaker leads installed in your car if the unit shares a common negative () lead for the right and left speakers.
Do not connect the units speaker leads to each other.Note on connectionIf speaker and amplifi er are not connected correctly, Failure appears in the display. In this case, make sure the speaker and amplifi er are connected correctly.
