IMPORTANT SAFETY PRECAUTIONS

Product Safe ty Notice
Some electrical and mechanical parts have special safety-related characteristi cs 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 whi ch they are to be sold. H owever, in order to maintain su ch com plian ce, it is eq ual ly im por­tant 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 sp uriou s radiation . These must al so 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 wi res do no t c ont act he at p ro duc-
ing par ts (heat sink s, oxide metal film resi stors, fus­ible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has b een replac ed, che ck that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surroundin g repa ired 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 mm 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, di sconnect the AC plug from the AC outlet.
1-3-1 DVD_SFNP
Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deter ioration. Observe that scr ews, 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 clearanc e distance (d) and (d’) between sol­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)
Table 1 : Ratings for selected area
AC Line Voltage Clearance Distance (d), (d’)
230 V
Note: This table is unofficial and for reference only.
Be sure to confirm the precise values.
3 mm(d)
6 mm(d’)
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) :

Instructions for Handling Semi-conductors
Electrostatic breakdown of the semi-conductors may occur due to a potential di fference caused by electro­static charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a groun ding band (1M ) 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 (1M) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape thr ough the body ground­ing band, be careful t o avoid contacting semi-con­ductors with your clothing.
