SERVICE NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostat­ic break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The fl exible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused
on the disc refl ective surface by the objective lens in the optical
pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

TEST DISCS

Please use the following test discs for the check on the CD section.

YDES-18 (Part No. 3-702-101-01)

TD-012 (Part No. 4-225-203-01)

PA

CAUTION

Use of controls or adjustments or performance of procedures other than
those specifi ed herein may result in hazardous radiation exposure.

If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fi xed resistor located at the side of optical
pick-up block.

UNLEADED SOLDER

Boards 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 with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded 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 be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 °C.
Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscous (sticky, less prone to fl ow)

than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

sintonizzatore oppure la funzione TA (notiziario sul traffico) o
AF (frequenza alternativa).

• Se l’automobile è dotata di antenna FM/MW/LW incorporata
nel vetro posteriore/laterale, collegare il cavo (blu) di
controllo dell’antenna elettrica o il cavo (rosso) di ingresso
dell’alimentazione accessoria al terminale di alimentazione
del preamplificatore dell’antenna esistente.Per ulteriori
informazioni, consultare il proprio fornitore.

• Non è possibile usare un’antenna elettrica senza scatola a relè
con questo apparecchio.

Collegamento per la conservazione della memoria

Quando il cavo di ingresso alimentazione giallo è collegato,
viene sempre fornita alimentazione al circuito di memoria anche
quando l’interruttore di accensione è spento.

Note sul collegamento dei diffusori

• Prima di collegare i diffusori spegnere l’apparecchio.

• Usare diffusori di impedenza compresa tra 4 e 8 ohm e con

capacità di potenza adeguata, altrimenti i diffusori potrebbero
venire danneggiati.

• Non collegare i terminali del sistema diffusori al telaio dell’auto
e non collegare i terminali del diffusore destro a quelli del
diffusore sinistro.

• Non collegare il cavo di messa a terra di questo apparecchio al
terminale negativo (–) del diffusore.

• Non collegare i diffusori in parallelo.

• Assicurarsi di collegare soltanto diffusori passivi, poiché

il collegamento di diffusori attivi, dotati di amplificatori
incorporati, ai terminali dei diffusori potrebbe danneggiare
l’apparecchio.

• Per evitare problemi di funzionamento, non utilizzare i cavi dei
diffusori incorporati installati nell’automobile se l’apparecchio
condivide un cavo comune negativo (–) per i diffusori destro e
sinistro.

• Non collegare fra loro i cavi dei diffusori dell’apparecchio.

Nota sui collegamenti

Aansluitschema

" Naar AMP REMOTE IN van een optionele

eindversterker

Deze aansluiting is alleen bedoeld voor versterkers. Door
een ander systeem aan te sluiten kan het apparaat worden
beschadigd.

# Naar het interface-snoer van een

autotelefoon

Waarschuwing

Indien u een elektrische antenne hebt zonder relaiskast,
kan het aansluiten van dit apparaat met het bijgeleverde
netsnoer  de antenne beschadigen.

Opmerkingen over de bedienings- en voedingskabels

• De antennevoedingskabel (blauw) levert +12 V gelijkstroom
wanneer u de tuner inschakelt of de AF (Alternative
Frequency) ofTA (Traffic Announcement) functie activeert.

• Wanneer uw auto is uitgerust met een FM/MW/LW-antenne
in de achterruit/zijruit, moet u de antennevoedingskabel
(blauw) of de hulpvoedingskabel (rood) aansluiten op de
voedingsingang van de bestaande antenneversterker.
Raadpleeg uw dealer voor meer details.

• Met dit apparaat is het niet mogelijk een automatische antenne
zonder relaiskast te gebruiken.

Instandhouden van het geheugen

Zolang de gele voedingskabel is aangesloten, blijft de
stroomvoorziening van het geheugen intact, ook wanneer het
contact van de auto wordt uitgeschakeld.

Opmerkingen betreffende het aansluiten van de luidsprekers

• Zorg dat het apparaat is uitgeschakeld, alvorens de
luidsprekers aan te sluiten.

• Gebruik luidsprekers met een impedantie van 4 tot 8 Ohm
en let op dat die het vermogen van de versterker kunnen
verwerken. Als u dit niet doet, kunnen de luidsprekers ernstig
beschadigd raken.

• Verbind in geen geval de aansluitingen van de luidsprekers
met het chassis van de auto en sluit de aansluitingen van de
rechter- en linkerluidspreker niet op elkaar aan.

• Verbind de aardingskabel van dit apparaat niet met de
negatieve (–) aansluiting van de luidspreker.

• Probeer nooit de luidsprekers parallel aan te sluiten.

• Sluit geen actieve luidsprekers (met ingebouwde versterkers)
aan op de luidsprekeraansluiting van dit apparaat. Dit zal
leiden tot beschadiging van de actieve luidsprekers. Sluit dus
altijd uitsluitend luidsprekers zonder ingebouwde versterker
aan.

• Om defecten te vermijden mag u de bestaande
luidsprekerbedrading in uw auto niet gebruiken wanneer er een
gemeenschappelijke negatieve (–) draad is voor de rechter- en
linkerluidsprekers.

• Verbind de luidsprekerdraden niet met elkaar.

Opmerking over aansluiten

Als de luidspreker en versterker niet correct zijn aangesloten,
wordt "FAILURE" in het displayweergegeven. In dit geval moet u
zorgen dat de luidspreker en versterker correct zijn aangesloten.
