(No.YD085)1-3 SECTION 1 PRECAUTION 1.1 SAFTY PRECAUTIONS Prior to shipment from the factory, 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. 1.1.1 Precautions 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 manuals. (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 with 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 - Double 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, 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 cord 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 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 can increase the high volt- age value and cause X-ray emission from the cathode ray tube. (12) Crimp type wire connectorIn such cases as when replacing the power transformer in sets where the connections be- tween the power cord and power trans former primary lead wires are performed using crimp type connectors, if replac- ing the connectors is unavoidable, in order to prevent safe- ty 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. -Replacement 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. 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 four points noted in Fig.1-1-7.
