Safety Precautions

1. This design of 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 parts must be identical to those

used in the original circuits.

Services 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 manufacturer`s

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 products 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 characteristics are identified in

the Parts List of Service Manual.

Electrical components having such features are identified by

shading on the schematics and by (

) on the Parts List in the Service Manual.

The use of a

substitute replacement which does not have the same safety characteristics as the recommended

replacement parts 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, moving parts and/or sharp edges

for the prevention of electric shock and fire hazard.

When service is required, the original lead

routing and dress should be observed, and it should be confirmed that they have been returned

to normal, after re-assembling.

5. Leakage currnet 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 transformer during this check.

Plug the AC line cord directly into the AC outlet.

Using a "Leakage Current Tester", measure

the leakage

current from each exposed metal parts of the cabinet , particularly any exposed

metal part having a return path to the chassis, to a known good earth ground. Any leakage

current must not exceed 0.5mA AC (r.m.s.)

Alternate check method

Plug the AC line cord directly into the AC outlet.

Use an AC voltmeter having, 1,000 ohms

per volt or more sensitivity in the following manner. Connect a 1,500

10W resistor paralleled by

a 0.15 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 eachexposed metal

part, particularly any exposed metal part having a

return path to the chassis, and meausre the AC

voltage across the resistor. Now, reverse the plug in

the AC outlet and repeat each measurement. voltage

measured Any must not exceed 0.75 V AC (r.m.s.).

This corresponds to 0.5 mA AC (r.m.s.).

Warning

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 maintained.

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.

Good earth ground

Place this

probe on

each exposed

metal part.

! CAUTION Burrs formed during molding may be left over on some parts of the chassis. Therefore,

pay attention to such burrs in the case of preforming repair of this system.

Important for laser products

1.CLASS 1 LASER PRODUCT

2.DANGER : Invisible laser radiation when open and inter

lock failed or defeated. Avoid direct exposure to beam.

3.CAUTION : There are no serviceable parts inside the

Laser Unit. Do not disassemble the Laser Unit. Replace

the complete Laser Unit if it malfunctions.

4.CAUTION : The compact disc player uses invisible

laserradiation and is equipped with safety switches

whichprevent emission of radiation when the drawer is

open and the safety interlocks have failed or are de

feated. It is dangerous to defeat the safety switches.

5.CAUTION : If safety switches malfunction, the laser is able

to function.

6.CAUTION : Use of controls, adjustments or performance of

procedures other than those specified herein may result in

hazardous radiation exposure.

VARNING : Osynlig laserstrålning är denna del är öppnad

och spårren är urkopplad. Betrakta ej strålen.

VARO

: Avattaessa ja suojalukitus ohitettaessa olet

alttiina näkymättömälle lasersäteilylle.Älä katso

säteeseen.

ADVARSEL : Usynlig laserstråling ved åbning , når

sikkerhedsafbrydere er ude af funktion. Undgå

udsættelse for stråling.

ADVARSEL : Usynlig laserstråling ved åpning,når

sikkerhetsbryteren er avslott. unngå utsettelse

for stråling.
