12、 PickupTurntable1-3-1B1N_ISPIMPORTANT SAFETY PRECAUTIONSProduct Safety NoticeSome electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components

13、 rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by 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 othe

14、r hazards. The Products 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 electrical codes of the countries in which they are to be sold.

15、 However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.Precautions during ServicingA. Parts identified by the # symbol are critical for safety. Replace only with part number specified.B. In addition to safety, other

16、 parts and assemblies are specified for conformance with regulations applying to spurious radiation. These must also be replaced only with specified replacements. Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.C. Use specified internal wiring. Note esp

17、ecially:1) Wires covered with PVC tubing2) Double insulated wires3) High voltage leadsD. Use specified insulating materials for hazardous live parts. Note especially:1) Insulation tape2) PVC tubing 3) Spacers4) Insulators for transistorsE. When replacing AC primary side components (transformers, pow

18、er cord, etc.), wrap ends of wires securely about the terminals before soldering.F.Observe that the wires do not contact heat producing parts (heat sinks, oxide metal film resistors, fusible resistors, etc.).G. Check that replaced wires do not contact sharp edges or pointed parts.H. When a power cor

19、d has been replaced, 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. When connecting or disconnecting the internal connectors, first, d

20、isconnect the AC plug from the AC outlet.1-3-2B1N_ISPSafety Check after ServicingExamine 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 sp

21、ecified values to verify compliance with safety standards.1. Clearance DistanceWhen replacing primary circuit components, confirm specified clearance distance (d) and (d) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)Table 1: Ratings for selected areaN

22、ote:This table is unofficial and for reference only. Be sure to confirm the precise values.2. Leakage Current TestConfirm 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 audi

23、o 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 te

24、rminals 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.

(Fig. S-1-6)CAUTION:1.The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC de

30、soldering machine, whose shape matches that of the Flat Pack-IC.2.Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage. (Fig. S-1-2)Top ViewOutInBotto
