WARNING AND LASER SAFETY INSTRUCTIONS

GB

WARNING

All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce
life drastically.
When repairing, make sure that you are
connected with the same potential as the
mass of the set via a wrist wrap with
resistance.
Keep components and tools also at this
potential.

F

ATTENTION

D

WARNUNG

I

WAARSCHUWING

AVVERTIMENTO

NL

Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor elektrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie
kan de levensduur drastisch doen
verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.

Tous les IC et beaucoup d’autres semi­conducteurs sont sensibles aux décharges
statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution
n’est prise a leur manipulation.
Lors de réparations, s’assurer de bien être
relié au même potentiel que la masse de
l’appareil et enfiler le bracelet serti d’une
résistance de sécurité.
Veiller a ce que les composants ainsi que les
outils que l’on utilise soient également a ce
potentiel.

GB

Safety regulations require that the set be restored to its original condition
and that parts which are identical with those specified be used.

NL

Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke
toestand wordt terug gebracht en dat onderdelen, identiek aan de
gespecifieerde worden toegepast.

Alle IC und viele andere Halbleiter sind
empfindlich gegen elektrostatische
Entladungen (ESD).
Unsorgfältige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafür, das Sie im Reparaturfall
über ein Pulsarmband mit Widerstand mit
dem Massepotential des Gerätes verbunden
sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls
auf diesem Potential.

D

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.
Der Originalzustand des Gerats darf nicht verandert werden.
Fur Reparaturen sind Original-Ersatzteile zu verwenden.

I

Le norme di sicurezza esigono che l’apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.

Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello
della massa dell’apparecchio tramite un
braccialetto a resistenza.
Assicurarsi che i componenti e anche gli
utensili con quali si lavora siano anche a
questo potenziale.

F

“Pour votre sécurité, ces documents
doivent être utilisés par des
spécialistes agrées, seuls habilités à
réparer votre appareil en panne.”

Les normes de sécurité exigent que l’appareil soit remis a l’état d’origine et
que soient utilisées les pièces de rechange identiques à celles spécifiées.

LASER SAFETY

This unit employs a laser. Only a qualified service person should remove the cover or attempt to service this
device, due to possible eye injury.

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURE OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

AVOID DIRECT EXPOSURE TO BEAM

WARNING

The use of optical instruments with this product will increase eye hazard.

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.

IMPORTANT SAFETY PRECAUTIONS

Product Safety Notice

Some electrical and mechanical parts have special
safety-related characteristics which are often not evi­dent from visual inspection, nor can the protection
they give necessarily be obtained by replacing them
with components rated for higher voltage, wattage,
etc. Parts that have special safety characteristics are
identified by a ! on schematics and in parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might create shock, fire, and/or other
hazards. The Product’s Safety is under review contin­uously and new instructions are issued whenever
appropriate. Prior to shipment from the factory, our
products are carefully inspected to confirm with the
recognized product safety and electrical codes of the
countries in which they are to be sold. However, in
order to maintain such compliance, it is equally impor­tant to implement the following precautions when a set
is being serviced.

Precautions during Servicing

A. Parts identified by the ! symbol are critical for

safety. Replace only with part number specified.

B. In addition to safety, other parts and assemblies

are specified for conformance with regulations
applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise block­ing capacitors, and noise blocking filters, etc.

C. Use specified internal wiring. Note especially:

1)Wires covered with PVC tubing

2)Double insulated wires

3)High voltage leads

D. Use specified insulating materials for hazardous

live parts. Note especially:

1)Insulation tape

2)PVC tubing

3)Spacers

4)Insulators for transistors

E. When replacing AC primary side components

(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before solder­ing.

F. Observe that the wires do not contact heat produc-

ing parts (heatsinks, oxide metal film resistors, fus­ible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord has been replaced, check that

5 - 6 kg of force in any direction will not loosen it.

I. Also check areas surrounding repaired locations.
J. Be careful that foreign objects (screws, solder

droplets, etc.) do not remain inside the set.

K. Crimp type wire connector

The power transformer uses crimp type connectors
which connect the power cord and the primary side
of the transformer. When replacing the transformer,
follow these steps carefully and precisely to pre­vent shock hazards.
Replacement procedure

1)Remove the old connector by cutting the wires at a
point close to the connector.

Important: Do not re-use a connector. (Discard it.)

2)Strip about 15 mm of the insulation from the ends
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.

3)Align the lengths of the wires to be connected.
Insert the wires fully into the connector.

4)Use a crimping tool to crimp the metal sleeve at its
center. Be sure to crimp fully to the complete clo­sure of the tool.

L. When connecting or disconnecting the internal con-

nectors, first, disconnect the AC plug from the AC
outlet.

1-3-1 DVD_SFNP

Safety Check after Servicing

Examine the area surrounding the repaired location for
damage or deterioration. Observe that screws, parts,
and wires have been returned to their original posi­tions. Afterwards, do the following tests and confirm
the specified values to verify compliance with safety
standards.

1. Clearance Distance

When replacing primary circuit components, confirm
specified clearance distance (d) and (d’) between sol­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)

≥ 6 mm(d’)

2. Leakage Current Test

Confirm the specified (or lower) leakage current
between B (earth ground, power cord plug prongs)
and externally exposed accessible parts (RF termi­nals, antenna terminals, video and audio input and
output terminals, microphone jacks, earphone jacks,
etc.) is lower than or equal to the specified value in the
table below.

Measuring Method (Power ON) :

Insert load Z between B (earth ground, power cord
plug prongs) and exposed accessible parts. Use an
AC voltmeter to measure across the terminals of load
Z. See Fig. 2 and the following table.

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 (1MΩ) that is prop­erly grounded to remove any static electricity that may
be charged on the body.

2. Ground for Workbench

(1) 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.
