IMPORTANT SAFETY PRECAUTIONS

Product Safe t y 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 characteri stic s are ide ntified 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 haz ards. 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 produ ct safety and electrical co des of the countries in which they are to be sold. However, in order to maintain such com plian ce, it is eq ually impor tant 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 spu riou s radiation . These must al so be replaced only with specified replacements. Examples: RF converters, RF ca bles, 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 wi res do no t contact heat produc-

ing parts (heat sink s, oxide metal film resisto rs, fusible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord h as been replaced , check tha t

5 - 6 kg of force in any direction will not loosen it.

I. Also check areas surrounding repa ir ed loc at ion s.

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 m m of the insulat ion 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, dis connect the AC plug from the AC outlet.

Safety Check after Servicing

Examine the area surrounding the repaired location for damage or deter ioration. Observe that screws, par ts, 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 clearance distance ( d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)

Table 1 : Ratings for selected area

Note: This table is unofficial and for reference only.

Be sure to confirm the precise values.

2. Leakage Current Test

Confirm the specified (or lower) leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) is lower than or equal to the specified value in the table below.

Measuring Method (Power ON) :

Insert load Z between B (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure across the ter minals of load Z. See Fig. 2 and the following table.

Instructions for Handling Semi-conductors

Electrostatic breakdown of the semi-conductors may occur due to a potential difference caus ed by electrostatic charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a groundin g ban d (1M Ω) that is properly grounded to re move any static electr ici ty that may be charged on the body.

2. Ground for Workbench

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

with proper grounding (1MΩ) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape throu gh the body grounding band, be careful to avoid contacting s emi-conductors with your clothing.

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTS

Standard Notes WARNING

Many electrical and mechanical parts in t his chassis have special characteristics. These characteristics often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement par ts that have these special safety characteristics are identified in this manual and its supplements; electrical components having such features are identified by the mark " ! " in the schematic diagram and the parts list. Before replacing any of these components, read the pa rts list in this manual carefully. The use of substitute replacemen t par ts that do not have the same safety characteristics as specified in the par ts list may create shock, fire, or other hazards.

Notes:

1. Do not use the par t number sh own on these drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since these drawings were prepared.

2. All resistance values are indicated in ohms (K=10

3

, M=106).

3. Resistor wattages are 1/4W or 1/6W unless o therwise specified.

4. All capacitance values are indicated in µF (P=10

-6

µF).

5. All voltages are DC voltages unless otherwise specified.

6. Electrical parts such as capacitors, connectors, diodes, IC’s, transistors, resistors, switches, and fuses are identified by four digits. The first two digits are not shown for each component. In each block of the diagram, there is a note such as shown below to indicate these abbreviated two digits.
