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 posi-

tions. 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 sol-

dered terminals, and between terminals and surround-

ing metallic parts. (See Fig. 1)

Table 1: Ratings for selected area

Note: This table is unofficial and for reference only.

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 termi-

nals, 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.
