I Safety Precautions

t. The design this product contains special hardware and many circuits and components specially for safety purposes. For continued
protection. no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement pans
must be identical to those used in the original circuits. Service should be performed by qualified personnel only.

2. Alterations of the design or circuitry of the product should not be made. Any design alterations of the product should not be made.
Any design alterations or additions will void the manufactures warranty and will further relieve the manufacture of responsibility
for personal injury or property damage resulting therefrom.

3. Many electrical and mechanical parts in the product have special safety - related characteristics. These characteristics are often
not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement
components rated for higher voltage. wattage. etc. Replacement parts which have these special safety characleristics are
identified in the parts list of service manual. Electrical components having such features are identified by shading(EI:l) and (A )
on the schematic diagram and pans list in the service manual. The use of a substitute replacement which does not have the same
safety characteristics as the recommended replacement part shown in the parts list of service manual may create shock. fire. or
other hazards.

4. The leads in the products are routed and dressed with ties. clamps . tubings. barriers and the like to be separated from live parts.
high temperature parts. mpving parts and or sharp edges for the prevention of electric shock and fire hazard. When sen/ice is
required. the original lead routing and dress should be observed. and it should be confirmed that they have been returned to
normal. after reassembling.

5. Leakage current check (Electrical shock hazard testing)

After re - assembling the product, always perform an isolation check on the exposed metal parts of the product (antenna

terminals. knobs. metal cabinet. screw heads. headphone jack. control shafts. etc.) to be sure the product is safe to operate

without danger of electrical shock. Do not use a line isolation

- Alternate check method

Plug the AC line cord directly into the AC outlet. Use an AC 600d earth ground
voltmeter having 1.000 ohms per volt or more sensitivity in the following manner. Connect a 1.500 ohms 10W resistor paralleled
by a 0.15 .11 F AC type capacitor between an exposed metal part and a known good earth ground. Measure the AC voltage
across the resistor with the AC voltmeter. Move the resistor connection to each exposed metal part. particularly any exposed
metal part having a return path to the chassis. and measure the AC voltage across the resistor. Now. reverse the plug in the AC
outlet and repeat each measurement. Any voltage measured must not exceed 0.75V AC(r.m.s.).This corresponds to 0.5mA

AC(r.m.s.).

warning (UK ONLY)

1. This equipment has been designed and manufactured to meet international safety standards.

2. It is the legal responsibility of the repairer to ensure that these safety standards are maintaintaind.
3. Repairs must be made in accordance with the relevant safety standards.

4. It is essential that safety critical components are replaced by approved parts.

5. If mains voltage selector is provided. check setting for local voltage.
