IMPORTANT SAFETY PRECAUTIONS

3/21/2018

Digitized in Heiloo Netherlands

Product Safety Notice

Some electrical and mechanical parts have special
safety-related characteristic s 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 afety characteristics are
identifi ed b y 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 electr ical codes of the
countries in which they are to be sold. However, in
order to maintain such compliance, it is e qual ly imp or ­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 radi ation. Thes e must also be
replaced only with specified replacements.
Examples: RF conver ters, 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 no t co ntac t he at prod uc -

ing parts (heatsink s, oxide metal film resist ors, fus­ible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord has b een replac ed, 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 insu lation 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 complet e clo­sure of the tool.

L. When connecting or disconnecting the internal

connectors, first, disconne ct the AC plug from the
AC outlet.

Safety Check after Servicing

3/21/2018

Digitized in Heiloo Netherlands

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 Distan ce

When replacing primary circuit components, confirm
specified clearance dista nce (d) and (d’) between sol ­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)

2. Leakage Curre nt 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 t he ter minals of l oad

Semi-conductors

Electrostatic breakdown of the semi-conductors may
occur due to a potenti al difference caused by electro ­static charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a groundi ng ban d (1M Ω) that is prop­erly grounded to remove any static electr icity 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 wor kbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escap e through the body ground­ing band, be care ful to avoid contacting semi-con ­ductors with your clothing.
