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 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.
This compact disc player is classified as a CLASS 1 LASER
product. The CLASS 1 LASER PRODUCT label is located on the
exterior.
This label is located on the bottom of the chassis.
• CD playback
You can play CD-DA (also containing CD TEXT) and CD-R/
CD-RW (MP3/WMA files).
Type of discs
Label on the disc
CD-DA
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 specified 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-fixed 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 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.

amplifier
2 Al cable de control de la antena motorizada
First connect the black ground (earth) lead, then connect the
yellow, and red power supply leads.
Notes
• 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/AM antenna (aerial) in
the rear/side glass, see “Notes on the control and power
supply leads.”
3 To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers. 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 (earth) lead to a
metal surface of the car first.
• When your car has a built-in FM/AM antenna (aerial) 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 (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/AM 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 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 (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
amplifier are connected correctly.

Notas
• Si no se dispone de antena motorizada ni de amplificador
de antena, o se utiliza una antena telescópica accionada
manualmente, no será necesario conectar este cable.
• Si el automóvil incorpora una antena de FM/AM en el
cristal trasero o lateral, consulte “Notas sobre los cables
de control y de fuente de alimentación”.

Notas
• Si no hay posición de accesorio, conéctelo al terminal de
alimentación (batería) de +12 V que recibe energía sin
interrupción.
Asegúrese de conectar primero el cable de conexión a
masa negro a una superficie metálica del automóvil.
• Si el automóvil incorpora una antena de FM/AM en el
cristal trasero o lateral, consulte “Notas sobre los cables
de control y de fuente de alimentación”.
5 Al terminal de alimentación de +12 V que
recibe energía sin interrupción
Asegúrese de conectar primero el cable de conexión a masa
negro a una superficie metálica del automóvil.
Notas sobre los cables de control y de fuente de
alimentación
• El cable de control de la antena motorizada (azul) suministrará
cc de + 12 V cuando conecte la alimentación del sintonizador.
• Si el automóvil dispone de una antena de FM/AM incorporada
en el cristal trasero o lateral, conecte el cable de control de
antena motorizada (azul) o el cable de fuente de alimentación
auxiliar (rojo) al terminal de alimentación del amplificador de
antena existente. Para obtener más información, consulte a su
distribuidor.
• Con esta unidad no es posible utilizar una antena motorizada
sin caja de relé.
Conexión para protección de la memoria
Si conecta el cable de fuente de alimentación amarillo, el circuito
de la memoria recibirá siempre alimentación, aunque apague el
interruptor de encendido.
Notas sobre la conexión de los altavoces
• Antes de conectar los altavoces, desconecte la alimentación
de la unidad.
• Utilice altavoces con una impedancia de 4 a 8 Ω con la
capacidad de potencia adecuada para evitar que se dañen.
• No conecte los terminales de altavoz al chasis del automóvil,
ni conecte los terminales del altavoz derecho con los del
izquierdo.
• No conecte el cable de conexión a masa de esta unidad al
terminal negativo (–) del altavoz.
• No intente conectar los altavoces en paralelo.
• Conecte solamente altavoces pasivos. Si conecta altavoces
activos (con amplificadores incorporados) a los terminales de
altavoz, puede dañar la unidad.
• Para evitar fallas de funcionamiento, no utilice los cables de
altavoz incorporados instalados en el automóvil si la unidad
comparte un cable negativo común (–) para los altavoces
derecho e izquierdo.
• No conecte los cables de altavoz de la unidad entre sí.
Nota sobre la conexión
Si el altavoz no está conectado correctamente, aparecerá
“FAILURE” en la pantalla. Si es así, compruebe la conexión del
altavoz.
