SERVICE NOTES

CAUTION

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

This label is located on the bottom of the chassis.

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

The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible 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 reflective 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.

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

CD-R test disc TCD-R082LMT (Part No. J-2502-063-1)
CD-RW test disc TCD-W082L (Part No. J-2502-063-2)

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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead
free 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 flow)
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.

EXTENSION CABLE AND SERVICE POSITION

When repairing or servicing this set, connect the jig (extension cable)
as shown below.

• Connect the MAIN board (CNP301) and the SER VO board (CN1)
with the extension cable (Part No. J-2502-076-1).

Connection diagram

1 To a metal surface of the car

First connect the black ground lead, then connect the yellow
and red power input leads.

2 To the power antenna control lead or power

supply lead of antenna booster amplifi er

Notes

•

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

•

When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply
leads.”

3 To AMP REMOTE IN of an optional power

amplifi er

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

4 To the +12 V power terminal which is

energized in the accessory position of the
ignition key switch

Notes

•

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

•

When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply
leads.”

5 To the +12 V power terminal which is

energized at all times

Be sure to connect the black ground lead to a metal surface
of the car fi rst.

Notes on the control and power supply leads

•

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

•

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

•

A power antenna without a relay box cannot be used with this
unit.

Memory hold connection

When 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 ground 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 unit’s speaker leads to each other.

Note on connection

If 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.

permanence

Raccordez d’abord le câble de mise à la masse noir à un

point métallique du véhicule.

Le câble de commande d’antenne électrique (bleu) fournit une
alimentation de +12 V CC lorsque vous mettez la radio sous
tension.
Lorsque votre voiture est équipée d’une antenne FM/AM
intégrée dans la vitre arrière/latérale, raccordez le câble de
commande d’antenne (bleu) ou l’entrée d’alimentation des
accessoires (rouge) à la borne d’alimentation de l’amplifi cateur
d’antenne existant. Pour plus de détails, consultez votre
détaillant.
Une antenne électrique sans boîtier de relais ne peut pas être
utilisée avec cet appareil.

Avant de raccorder les haut-parleurs, mettez l’appareil hors
tension.
Utilisez des haut-parleurs ayant une impédance de 4 à 8 ohms
avec une capacité électrique adéquate pour éviter de les
endommager.
Ne raccordez pas les bornes du système de haut-parleurs au
châssis de la voiture et ne raccordez pas les bornes des haut­parleurs droit à celles du haut-parleur gauche.
Ne raccordez pas le câble de mise à la masse de cet appareil
à la borne négative (–) du haut-parleur.
N’essayez pas de raccorder les haut-parleurs en parallèle.
Raccordez uniquement des haut-parleurs passifs. Le
raccordement de haut-parleurs actifs (avec amplifi cateurs
intégrés) aux bornes des haut-parleurs peut endommager
l’appareil.
Pour éviter tout dysfonctionnement, n’utilisez pas les câbles
des haut-parleurs intégrés installés dans votre voiture si
l’appareil partage un câble négatif commun (–) pour les haut­parleurs droit et gauche.
Ne raccordez pas entre eux les cordons des haut-parleurs de
l’appareil.

THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)

For schematic diagrams.

Note:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.

• All resistors are in Ω and 1/
specified.

f

•

: internal component.

4

W or less unless otherwise

• C : panel designation.

Note:

The components identi­fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.

Note:

Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.

• A : B+ Line.

• B : B– Line.

• H : adjustment for repair.

•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• CD mechanism section

no mark : CD PLAY

• Main (1/3), (2/3), (3/3) and Key sections

no mark : FM

(): AM
<>: CD PLAY

∗ : Impossible to measure

•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc­tion tolerances.

•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc­tion tolerances.

• Circled numbers refer to waveforms.

• Signal path.

J : CD PLAY
F : FM
f : AM
L : AUX

For printed wiring boards.

Note:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.
