IMPORTANT SAFETY PRECAUTIONS

Product Safety Notice

Some electrical and mechanical parts have special
safety-related charac teristics 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 s afe ty c har ac te rist ic s ar e i den ­tified 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, fi re, 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 prod uct safety and electrical codes of
the countries in whic h th ey are to be sold. However, in
order to maintain such comp lianc e, it is equ ally impor ­tant 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 spur ious rad iation. T hese m ust also be
replaced only with specified re pla ce men ts.
Examples: RF converters, RF c ables, 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 wir es do n ot co ntact h eat pr od uc -

ing parts (heatsinks, oxide metal fil m re sisto rs, fus ­ible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord h as been repl aced, ch eck 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 tr ansformer 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 th e complete clo­sure of the tool.

L. When connecting or disconnecting the internal

connectors, first, discon nect the AC plug from the
AC outlet.

Safety Check after Servicing

Examine the area surrounding the repaired location for
damage or deterio ration. 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 cleara nce distanc e (d) and (d’) between sol ­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)

Be sure to confirm the precise values.

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 acr oss the ter minals of l oad
Z. See Fig. 2 and the following table.

Instructions for Handling
Semi-conductors

Electrostatic breakdown of the semi-conductors may
occur due to a po tential difference ca used by electr o­static charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a gr oundin g band (1MΩ) that is prop­erly grounded to re move any static electricity th at m ay
be charged on the body.

2. Ground for Workbench

(4) Be sure to place a conductive sheet or copper plate

with proper groundin g (1MΩ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will no t escape through the body ground­ing band, be careful to avoid contacting semi-con­ductors with your clothing.
