7DVD-2500BTCISafety Check after ServicingExamine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, andwires have been returned to their original positions. Afterwards, do the following tests and confirm the specifiedvalues to verify compliance with safety standards.1. Clearance DistanceWhen replacing primary circuit components, confirmspecified clearance distance (d) and (d’) betweensoldered terminals, and between terminals andsurrounding metallic parts. (See Fig. 1)Table 1: Ratings for selected areaNote: This table is unofficial and for reference only. Besure to confirm the precise values.2. Leakage Current TestConfirm the specified (or lower) leakage currentbetween B (earth ground, power cord plug prongs) andexternally exposed accessible parts (RF terminals,antenna terminals, video and audio input and outputterminals, microphone jacks, earphone jacks, etc.) islower than or equal to the specified value in the tablebelow.Measuring Method (Power ON):Insert load Z between B (earth ground, power cord plugprongs) and exposed accessible parts. Use an ACvoltmeter to measure across the terminals of load Z.See Fig. 2 and the following table.Table 2: Leakage current ratings for selected areasNote: This table is unofficial and for reference only.
