LASER BEAM SAFETY PRECAUTIONS

D
This DVD player uses a pickup that emits a laser beam.
Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin.
The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 30cm away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
Caution: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation exposure.

IMPORTANT SAFEGUARDS AND PRECAUTIONS

T M
1. IMPORTANT SERVICE NOTES
BEFORE RETURNING THE DVD VIDEO PLAYER Before returning the DVD video player to the user,
perform the following safety checks.
1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the DVD video player.
2. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and compartment covers or shields, isola­tion resistor/capacitor networks, mechanical insula­tors etc.
3. To be sure that no shock hazard exists, check for current in the following manner. Plug the AC line cord directly into a 230 volt AC outlet (Do not use an isolation transformer for this test). Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known earth ground, such as a water pipe or conduit. Use an DVM or VOM with 1000 ohm per volt, or higher, sensitivity or measure the AC voltage drop across the resistor (See Diagram). Move the resistor connection to earth exposed metal part having a return path to the chassis (metal cabinet, screw heads, knobs and control shafts, etc.) and measure the AC voltage drop across the resistor.
Reverse the AC plug on the set and repeat AC voltage measurements for each exposed part. Any reading of
1.4V rms (this corresponds to 0.7mA rms AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the DVD video player to the owner.

1. NOTES DE SERVICE IMPORTANTES
AVANT DE RENDRE LE REPRODUCTOR DE VíDEO DVD
Avant de rendre le reproductor de vídeo DVD à l’utilisateur, effectuer les vérifications de sécurité suivantes.
1. Vérifier toutes les gaines de fil pour être sûr que les fils ne sont pas pincés ou que le matériel n’est pas coincé entre le châssis et les autres pièces métalliques dans le reproductor de vídeo DVD.
2. Vérifier tous les dispositifs de protection tels que les boutons de commande non métalliques, les matériaux d’isolement, le dos du coffret, les couvercles de compartiment et ajustement ou les boucliers, les réseaux de résistance / condensateur d’isolement, Ies isolateurs mécaniques, etc.
3. Pour être sûr qu’il n’y a aucun risque de choc électrique, vérifier le courant de fuite de la maniére suivante. Brancher le cordon d’alimentation secteur directement dans une prise de courant de 230 volts. (Ne pas utiliser de transformateur d’isolement pour cet essai). Utiliser deux fils à pinces et connecter une résistance de 10 watts 1,5 kohm en parallèle avec un condensateur de 0,15 µF en série avec des pièces du coffret métallique exposées et une masse de terre connue telle qu’un tuyau ou un conduit d’eau. Utiliser un DVM ou VOM avec une sensibilité de 1000 ohms par volt ou plus ou mesurer la chute de tension CA entre la résistance (voir diagramme). Déposer la connexion de la résistance à toutes les
pièces métalliques exposées ayant un parcours de retour au châssis (coffret métallique, tétes de vis, bou­tons et arbres de commande, etc.) et mesurer la chute de tension CA entre la résistance. Inverser la fiche CA (une fiche intermédiaire non polarisée doit être utilisée à seule fin de faire ces vérifications.) sur l’appareil et répéter les mesures de tension CA pour chaque piéce métallique exposée. Toute lecture de 1,4 V rms (ceci correspond à 0,7 mA rms CA) ou plus est excessive et signale un danger de choc qui doit être corrigé avant de rendre le reproductor de vídeo DVD à son utilisateur.

Instructions for Connectors
1. When you connect or disconnect the FFC (Flexible Foil Connector) cable, be sure to first disconnect the AC cord.
2. FFC (Flexible Foil Connector) cable should be in­serted parallel into the connector, not at an angle.

Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldening bit, contact our service station or service ranch in your area.
Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder by 40°C, and as it has poor solder wettabillty, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be excoeded, remove the bit from the PWB as soon as you conurm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum on and off the power of the bit as required. if a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Becareful when replacing parts with polarity indication on the PWB silk.

Instructions for Handling Semi-conductors
Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1M) that is properly grounded to remove any static electricity that may be charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with proper grounding (1M) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.

three Locking Tabs (L-2) .
1-2. Release three Locking Tabs (L-3). Then remove
the Front Assembly.
CAUTION 2: Electrostatic breakdown of the laser diode in the optical system block may occur as a potential difference caused by electrostatic charge accumulated on cloth, human body etc., during unpacking or repair work.
To avoid damage of pickup follow next procedures. 2-1. Short the three short lands (either of two places) of
FPC cable with solder before removing the FFC cable (CN201) from it as shown in “View for A” in Fig. 4. If you disconnect the FFC cable (CN201), the laser diode of pickup will be destroyed. (Fig. 4)
2-2. Disconnect Connectors (CN301), (CN401) and
(CN601). Remove two Screws (S-3A) and (S-3B) and lift the DVD Main CBA Unit. (Fig. 4)
CAUTION 3: When reassembling, confirm the FFC cable (CN201) is connected completely. Then remove the solder from the three short lands of FPC cable. (Fig. 4)
