NOTES  ON  CHIP  COMPONENT  REPLACEMENT
•  Never reuse a disconnected chip component.
•  Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
NOTES  ON  HANDLING  THE  OPTICAL  PICK-UP  
BLOCK  OR  BASE  UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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.
CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion 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.
TEST  DISCS
Please use the following test discs for the check on the CD section.

TABLE  OF  CONTENTS
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 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.
Except US, Canadian model:
This label is located on the bottom of the chassis.

SECTION  1
SERVICE  NOTE
EXTENSION  CABLE  AND  SERVICE  POSITION
When repairing or servicing this set, connect the jig (extension 
cable) as shown below.
•  Connect the MAIN board (CN701) and the SERVO board 
(CN401) with the extension cable (Part No. J-2502-076-1).
NOTE FOR REPLACEMENT OF THE USB CONNECTOR 
(CN902)
To replace the USB connector requires alignment.
1.  Insert the USB connector into the front panel.
2.  Place the KEY board on the front panel and align the terminals 
of the USB connector with the holes in the KEY board.
3.  Solder the four terminals of the connector.
NOTE  FOR  REPLACEMENT  OF  THE  SERVO  BOARD
When repairing, the complete SERVO board (Part No. A-1768-
001-A) should be replaced since any parts in the SERVO board 
cannot be repaired.
NOTE  FOR  THE  20-PIN  CONNECTOR (CN901)
Do not use alcohol to clean the 20-pin connector (CN901) connect-
ing the front panel with the main body.
Do not touch the connector directly with your bare hand. Poor con-
tact may be caused.

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 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 amplifier are 
connected correctly.

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.”

A una superficie metálica del automóvil
Conecte primero el cable de conexión a masa negro, y después los 
cables amarillo y rojo de fuente de alimentación.
2
Al cable de control de la antena motorizada o al 
cable de fuente de alimentación del 
amplificador de señal de la antena
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”.
3
A AMP REMOTE IN de un amplificador de 
potencia opcional
Esta conexión es sólo para amplificadores. La conexión de cualquier 
otro sistema puede dañar la unidad.
4
Al terminal de alimentación de +12 V que recibe 
energía en la posición de accesorio del 
interruptor de encendido
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 impHGDQFLDGHDŸcon 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 y el amplificador no están conectados correctamente, 
aparecerá “FAILURE” en la pantalla. Si es así, compruebe la conexión de 
ambos dispositivos.
