Precautions during Servicing

A.Parts identified by the ( #) symbol are critical for safety.

Replace only with part number specified.

B.In addition to safety, other parts and assemblies are specified for conformance with regulations ap- plying to spurious radiation. These must also be replaced only with specified replacements.

Examples: RF converters, RF cables, noise block- ing capacitors, and noise blocking filters, etc.

C.Use specified internal wiring. Note especially:

1)Wires covered with PVC tubing

2)Double insulated wires

3)High voltage leads

D.Use specified insulating materials for hazardous live parts. Note especially:

1)Insulation Tape

2)PVC tubing

3)Spacers

4)Insulators for transistors.

E.When replacing AC primary side components (transformers, power cord, etc.), wrap ends of wires securely about the terminals before solder- ing.

F.Observe that the wires do not contact heat produc- ing parts (heatsinks, oxide metal film resistors, fus- ible resistors, etc.)

G.Check that replaced wires do not contact sharp edged or pointed parts.

H.When a power cord 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.Use care that foreign objects (screws, solder drop- lets, etc.) do not remain inside the set.

K.Crimp type wire connector

The power transformer uses crimp type connec- tors which connect the power cord and the primary side of the transformer. When replacing the trans- former, follow these steps carefully and precisely to prevent shock hazards.

Replacement procedure

1)Remove the old connector by cutting the wires at a point close to the connector.

Important: Do not re-use a connector (discard it).

2)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.

3)Align the lengths of the wires to be connected. In- sert the wires fully into the connector.

4)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.

L.When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC supply outlet.
