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.

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.

optical pick-up

semi-fixed resistor

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 dam-

aged by heat.

Notes on CD-Rs (recordable CDs)/CD-RWs (rewritable CDs)

This unit can play the following discs:

Type of discs Label on the disc

Audio CD

MP3 files

• Some CD-Rs/CD-RWs (depending on the equipment used for its recording or the condition of the disc) may not play on this unit.

• You cannot play a CD-R/CD-RW that is not finalized∗.

• You can play MP3 files recorded on CD-ROMs, CD-Rs, and

CD-RWs.

• A CD-R/CD-RW to which a session can be added can be played.

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.

∗ A process necessary for a recorded CD-R/CD-RW disc to be

played on the audio CD player.

Pour plus de détails, consultez votre détaillant.

• Une antenne électrique sans boîtier de relais ne peut pas être utilisée avec cet appareil.

Raccordement pour la conservation de la mémoire

Lorsque le fil d’entrée d’alimentation jaune est raccordé, le circuit de la mémoire est alimenté en permanence même si la clé de contact est sur la position d’arrêt.

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 hautparleurs au châssis de la voiture et ne raccordez pas les bornes des haut-parleurs droit à celles du hautparleur gauche.

• Ne raccordez pas le câble de masse de cet appareil à la borne négative (–) de l’enceinte.

•N’essa yez 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 hautparleurs peut endommager l’appareil.

•Pour éviter tout dysfonctionnement, n’utilisez pas les fils des haut-parleurs 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 hautparleurs de l’appareil.

Remarque sur le raccordement

Si les haut-parleurs et l’amplificateur ne sont pas raccordés correctement, le message « FAILURE » s’affiche. Dans ce cas, assurez-vous que les hautparleurs et l’amplificateur sont bien raccordés.
