LASER BEAM SAFETY PRECAUTIONS
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.
Location: Inside Top of DVD mechanism.

CAUTION -  VISIBLE LASER

INTERLOCK DEFEATED.
AVOID EXPOSURE TO BEAM.

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, isola-
tion resistor/capacitor networks, mechanical insula-
tors 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 0.15
µF 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, bou-
tons 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.
