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.

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 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as a water pipe or conduit.
UseanDVM or VOMwith1000 ohmper 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
1.4Vrms (thiscorresponds to 0.7mArms 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

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. Pourêtresûrqu’iln’yaaucunrisquedechocélectrique,
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
de10watts1,5kohmenparallèleavecuncondensateur
de0,15µFensérieavecdespiècesducoffretmétallique
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.

How to Remove / Install Flat Pack-IC
1. Removal
With Hot-Air Flat Pack-IC Desoldering Machine:
(1)Prepare the hot-air flat pack-IC desoldering ma-
chine, then apply hot air to the Flat Pack-IC (about 5
to 6 seconds). (Fig. S-1-1)
Fig. S-1-1
(2)Remove the flat pack-IC with tweezers while apply-
ing the hot air.
(3)Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
(4)Release the flat pack-IC from the CBA using twee-
zers. (Fig. S-1-6)
Caution:
1. Do not supply hot air to the chip parts around the flat
pack-IC for over 6 seconds because damage to the
chip parts may occur. Put masking tape around the
flat pack-IC to protect other parts from damage.
(Fig. S-1-2)
2. The flat pack-IC on the CBA is affixed with glue, so
be careful not to break or damage the foil of each pin
or the solder lands under the IC when removing it.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occurduetoapotentialdifferencecausedbyelectrostatic
charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) 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 (1MΩ) 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.
