IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some 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 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 other hazards. The Product’s 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. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
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 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 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 soldering.
F.Observe that the wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
G.Check that replaced wires do not contact sharp edges 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.Be careful that foreign objects (screws, solder droplets, etc.) do not remain inside the set.
K.Crimp type wire connector
The power transformer uses crimp type connectors which connect the power cord and the primary side of the transformer. When replacing the transformer, 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. Insert the wires fully into the connector.
4)Use a crimping tool to crimp the metal sleeve at its center. 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 outlet.

Instructions for Handling Semiconductors
Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1 MΩ ) that is properly grounded to remove any static electricity that may be charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with proper grounding (1 MΩ ) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.
