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

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.

Waarschuwing

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

Opmerkingen over de bedienings- en voedingskabels

• De bedieningskabel van de elektrische antenne (blauw) levert
+12 V gelijkstroom wanneer u de tuner inschakelt of de AF
(alternatieve frequenties) ofTA (verkeersinformatie) functie
activeert.

•

Wanneer uw auto is uitgerust met een FM/MW/L
in de achterruit/zijruit, moet u de bedieningskabel van de
elektrische antenne (blauw) of de voedingskabel van de
accessoires (rood) aansluiten op de voedingsingang van de
bestaande antenneversterker. Raadpleeg uw dealer voor meer
details.

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

Instandhouden van het geheugen

Zolang de gele voedingskabel is aangesloten, blijft de
stroomvoorziening van het geheugen intact, ook wanneer de
contactschakelaar 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 aardingskabel van de luidsprekers
met het chassis van de auto en sluit de aansluitingen van de
rechter- en linkerluidspreker niet op elkaar aan.

• Verbind de aarddraad 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)

Connection diagram

 To a metal surface of the car

First connect the black ground (earth) lead, then connect the
yellow and red power supply leads.

 To the power antenna (aerial) control lead or

power supply lead of antenna (aerial) booster

0QVGU

• It is not necessary to connect this lead if there is no power
antenna (aerial) or antenna (aerial) booster, or with a
manually-operated telescopic antenna (aerial).

• When your car has a built-in FM/MW/SW antenna (aerial)
in the rear/side glass, see “Notes on the control and power
supply leads.”

 To AMP REMOTE IN of an optional power

amplifier

This connection is only for amplifiers. Connecting any other
system may damage the unit.

 To the +12 V power terminal which is

energized in the accessory position of the
ignition switch

0QVGU

• If there is no accessory position, connect to the +12V
power (battery) terminal which is energized at all times.
Be sure to connect the black ground (earth) lead to a
metal surface of the car first.

• When your car has a built-in FM/MW/SW antenna (aerial)
in the rear/side glass, see “Notes on the control and power
supply leads.”

 To the +12 V power terminal which is

energized at all times

Be sure to connect the black ground (earth) lead to a metal
surface of the car first.

Notes on the control and power supply leads

• The power antenna (aerial) control lead (blue) supplies +12 V
DC when you turn on the tuner.

• When your car has built-in FM/MW/SW antenna (aerial) in the
rear/side glass, connect the power antenna (aerial) control
lead (blue) or the accessory power supply lead (red) to the
power terminal of the existing antenna (aerial) booster.For
details, consult your dealer.

• A power antenna (aerial) without a relay box cannot be used
with this unit.

Memory hold connection

When the yellow power supply 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 ground (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 amplifiers) 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 unit’s speaker leads to each other.

Note on connection

If speaker and amplifier are not connected correctly,“FAILURE”
appears in the display. In this case, make sure the speaker and
