SAFETY&PRECAUTIONS
SAFETY CHECK AFTER SERVING

Examine the area surrounding the repaired location for damage or deterioration. Observe that screw,
parts and wires have been returned to original positions. Afterwards, perform the following tests and con-
form the specified values in order to verify compliance with safety standards.

1. Insulation resistance test
Confirm the specified insulation resistance between power cord plug prong and externally exposed
parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, micro-
phone jacks, earphone jacks, etc.) is greater than values given in table 1 below.

2. Dielectric strengthen test
Confirm specified dielectric strengthen between
power cord plug prongs and exposed accessible parts
of the set (RF terminals, antenna terminals, video and
audio input output terminals, microphone jack, ear
phone jacks, etc.) is greater than values given table 1.

3. Clearance distance
When replacing primary circuit component, confirm specified clearance distance (d), (d') between sol-
dered terminals, and between terminals and surrounding metallic parts. See table below.

Rating for selected areas

Insulation Dielectric Clearance
AC Line Voltage Region
Resistance Strength Distance(d),(d)
100V Japan ] 1M/500V DC 1kV AC 1min. ]3
110 to 130V USA & Canada - 900V AC 1min. ] 3.2
Europe ] 6(d)
* 110 to 130V
Australia ] 10M/500V DC 4kV AC 1min. ] 8(d')

4. 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 termi-
nals, video and audio input output terminals, microphone
jacks, earphone jacks, etc.)
Measuring method:(Power ON) Insert load Z between
B(earth ground, power cord plug prongs) and exposed
accessible parts. Use on AC voltmeter to measure across both terminals of load Z. See figure2 and
following table.

Leakage current ratings for selected are as
