15、, JVC products are strictly in- spected to conform with the recognized product safety and elec- trical codes of the countries in which they are to be sold.However,in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced. 1.1.1P

16、recautions 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 manua

17、ls. (2) Parts identified by the symbol and shaded ( ) 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 wi

18、th various regulations regarding spu- rious radiation emission. (3) Fuse replacement caution notice. Caution for continued protection against fire hazard. Replace only with same type and rated fuse(s) as speci- fied. (4) Use specified internal wiring. Note especially: Wires covered with PVC tubing D

19、ouble insulated wires High voltage leads (5) Use specified insulating materials for hazardous live parts. Note especially: Insulation Tape PVC tubing Spacers Insulation sheets for transistors Barrier (6) When replacing AC primary side components (transformers, power cords, noise blocking capacitors,

20、 etc.) wrap ends of wires securely about the terminals before soldering. Fig.1-1-1 (7) Observe that wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.) (8) Check that replaced wires do not contact sharp edged or pointed parts. (9) When a power c

21、ord has been replaced, check that 10-15 kg of force in any direction will not loosen it. Fig.1-1-2 (10) Also check areas surrounding repaired locations. (11) Products using cathode ray tubes (CRTs) In regard to such products, the cathode ray tubes themselves, the high volt- age circuits, and related

22、 circuits are specified for compli- ance with recognized codes pertaining to X-ray emission. Consequently, when servicing these products, replace the cathode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these cir- cuits.Unauthorized modification c

23、an increase the high volt- age value and cause X-ray emission from the cathode ray tube. (12) Crimp type wire connector In such cases as when replac- ing the power transformer in sets where the connections between the power cord and power trans former primary lead wires are performed using crimp typ

24、e connectors, if replacing the connectors is unavoidable, in order to prevent safety hazards, perform carefully and precisely according to the following steps. Connector part number :E03830-001 Required tool : Connector crimping tool of the proper type which will not damage insulated parts. Replacem

25、ent procedure a) Remove the old connector by cutting the wires at a point close to the connector.Important : Do not re- use a connector (discard it). Fig.1-1-3 b) Strip about 15 mm of the insulation from the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.

26、Fig.1-1-4 c) Align the lengths of the wires to be connected. In- sert the wires fully into the connector. Fig.1-1-5 d) As shown in Fig.1-1-6, use the crimping tool to crimp the metal sleeve at the center position. Be sure to crimp fully to the complete closure of the tool. Fig.1-1-6 e) Check the fou

27、r points noted in Fig.1-1-7. Fig.1-1-7 (13) Battery replacement caution notice. CAUTION RISK OF EXPLOSION IF BATTERY IS RE- PLACED BY AN INCORRECTIVE TYPE.

Observe that screws

29、, parts and wires have been returned to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compli- ance with safety standards. (1) Insulation resistance test Confirm the specified insulation resistance or greater be- tween power cord plug

30、prongs and externally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, ear- phone jacks, etc.).See table 1 below. (2) Dielectric strength test Confirm specified dielectric strength or greater between power cord plug prongs and e

31、xposed accessible parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.). See Fig.1-1-11 below. (3) Clearance distance When replacing primary circuit components, confirm spec- ified clearance distance (d), (d) between so

32、ldered termi- nals, and between terminals and surrounding metallic parts. See Fig.1-1-11 below. Fig.1-1-8 (4) Leakage current test Confirm specified or lower leakage current between earth ground/power cord plug prongs and externally exposed ac- cessible parts (RF terminals, antenna terminals, video

33、and audio input and output terminals, microphone jacks, ear- phone jacks, etc.). Measuring Method : (Power ON) Insert load Z between earth ground/power cord plug prongs and externally ex- posed accessible parts. Use an AC voltmeter to measure across both terminals of load Z. See Fig.1-1-9 and follow

34、- ing Fig.1-1-12. Fig.1-1-9 (5) Grounding (Class 1 model only) Confirm specified or lower grounding impedance between earth pin in AC inlet and externally exposed accessible parts (Video in, Video out, Audio in, Audio out or Fixing screw etc.).Measuring Method: Connect milli ohm meter between earth

35、pin in AC inlet and exposed accessible parts. See Fig.1-1-10 and grounding specifications. Fig.1-1-10 Fig.1-1-11 Fig.1-1-12 NOTE : These tables are unofficial and for reference only.
