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 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. 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.
Note
This unit cannot be connected to a digital preamplifier or an equalizer. Design and specifications are subject to change without notice.
US, Canadian model: 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.

Remarques sur le raccordement des haut-parleurs
· 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 haut-parleurs droit à celles du haut-parleur gauche. · Ne raccordez pas le câble de masse de cet appareil à la borne négative () de l'enceinte. · N'essayez pas de raccorder les haut-parleurs en parallèle. · Raccordez uniquement des haut-parleurs passifs. Le raccordement de haut-parleurs actifs (avec amplificateurs intégrés) aux bornes des haut-parleurs peut endommager l'appareil. · Pour éviter tout dysfonctionnement, n'utilisez pas les fils des hautparleurs intégrés installés dans votre voiture si l'appareil partage un fil négatif commun () pour les haut-parleurs droit et gauche. · Ne raccordez pas entre eux les cordons des haut-parleurs de l'appareil.
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 amplifiers) to the speaker terminals may damage the unit. · To avoid a malfunction, do not use the built-in speaker wires 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 cords to each other.
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 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 toma a tierra 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 fallos de funcionamiento, no utilice los cables de altavoz incorporados instalados en el automóvil si su unidad comparte un cable negativo común () para los altavoces derecho e izquierdo. · No conecte los cables de altavoz de la unidad entre sí.
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.
Remarque sur le raccordement
Si les haut-parleurs et l'amplificateur ne sont pas raccordés correctement, le message « Failure » s'affiche. Dans ce cas, assurezvous que les haut-parleurs et l'amplificateur sont bien raccordés.
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.
