1-2 IMPORTANT SAFETY PRECAUTIONS

1-2-1 Product Safety Notice

Some electrical and mechanical parts have special safety-related charac teristics 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 s afe ty c har ac te rist ic s ar e i den tified 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, fi re, 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 prod uct safety and electrical codes of the countries in whic h th ey are to be sold. However, in order to maintain such comp lianc e, it is equ ally impor tant to implement the following precautions when a set is being serviced.

1-2-2 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 spur ious rad iation. T hese m ust also be replaced only with specified re pla ce men ts. Examples: RF converters, RF c ables, 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. O bs erv e t hat the wi r es do n ot co ntact h eat pr od uc -

ing parts (heatsinks, oxide metal fil m re sisto rs, fus ible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord has been r eplaced, ch eck 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 tr ansformer 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 th e complete closure of the tool.

L. When connecting or disconnecting the internal

connectors, first, discon nect the AC plug from the AC outlet.

1-2-3 Safety Check after Ser vicing

Examine the area surrounding the repaired location for damage or deterio ration. Observe that screws , parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards.

1. Clearance Distance

When replacing primary circuit components, confirm specified cleara nce distanc e (d) and (d’) between sol dered terminals, and between terminals and surrounding metallic parts. (See Fig. 1-2-1)

1-3-4 Instructions for Handling

Semi-conductors

Electrostatic breakdown of the semi-conductors may occur due to a po tential difference ca used by electr ostatic charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a gr oundin g band (1MΩ) that is properly grounded to re move any static electricity th at m ay be charged on the body.

2. Ground for Workbench

(1) Be sure to place a conductive sheet or copper plate

with proper groundin g (1MΩ) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will no t escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.
