Prior to shipment from the factory, the products are strictly inspected to conform with the recognized product
safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such com-
pliance, it is equally important to implement the following precautions when a set is being serviced.
•Precautions during Servicing
1. Locations requiring special caution are denoted by labels and inscriptions on the cabinet, chassis and
certain parts of the product. When performing service, be sure to read and comply with these and other
cautionary notices appearing in the operation and service manuals.
2. Parts identified by the symbol and shaded (
Y
) parts are critical for safety.
Replace only with specified part numbers.
Note : Parts in this category also include those specified to comply with X-ray emission standards for
products using cathode ray tubes and those specified for compliance with various regulations
regarding spurious radiation emission.
3. Use Specified internal wiring. Note especially:
1) Double insulated wires
2) High voltage leads
4. Use specified insulating materials for hazardous live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulation sheets for transistor
5. Observe that wires do not contact heat producing
parts (heatsinks, oxide metal film resistors, fusible
resistors, etc.)
6. Check that replaced wires do not contact sharp edged
or pointed parts.
7. 1) When a power cord has been replaced, check
that A mark is made on the cord, under strain,
near the aperture, and the flexible cord is
subjected 100 times to a pull of 40N for a duration
of 1 second each.
2) During the test, the cord shall not be displaced by
more than 2mm
8. Also check areas surrounding repaired locations.
9. The internal wiring is secured so as not to approach the heating parts and high voltage parts by its shape.
So, these wires must be restored to its former state.

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 original positions. Afterwards, perform the following tests and confirm the specified
values in order to verify compliance with safety standards.
•Insulation resistance test
confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone
jacks, earphone jacks, etc.) See table below.
•Dielectric strength test
Confirm specified dielectric strength or greater between power cord prongs and exposed accessible parts of
the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks,
earphone jacks, etc.) See table below.
•Clearance distance
When replacing primary circuit components, confirm
specified clearance distance (d), (d') between sol-
dered terminals, and between terminals and sur-
rounding metallic parts. See table below.
Table 1 : Ratings for selected areas
* Class II model only.
Note. This table is unofficial and for reference only. Be sure to confirm the precise values for your particular
country and locality.
•Leakage Current test
Confirm 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, micro-
phone jacks, earphone jacks, etc.)
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 both terminals of
load Z. See figure and following table.
Table 2:Leakage current ratings for selected areas.
Note. This table is for IEC member only. Be sure to confirm the precise values for your particular country and
Note. locality.
