SECTION 1

PRECAUTION

1.1 Safety Precautions

(1) This design of this product contains special hardware and

many circuits and components specially for safety purpos-

es. 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 per-

formed 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 manufacturers 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 characteris-

tics are often not evident from visual inspection nor can the

protection afforded by them necessarily be obtained by us-

ing replacement components rated for higher voltage, watt-

age, etc. Replacement parts which have these special

safety characteristics are identified in the Parts List of Ser-

vice 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 charac-

teristics 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 reassem-

bling.

(5) Leakage shock hazard testing

After reassembling the product, always perform an isola-

tion check on the exposed metal parts of the product (an-

tenna 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, particular-

ly any exposed metal part having a return path to the

chassis, to a known good earth ground. Any leakage cur-

rent 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, 1,000Ωper volt or more sensitivity

in the following manner. Connect a 1,500Ω10W resistor

paralleled by a 0.15µF AC-type capacitor between an ex-

posed 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. Voltage measured any must

not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5

mA AC (r.m.s.).

1.2 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.

1.3 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 pre-

forming repair of this system.

1.4 Critical parts for safety

In regard with component parts appearing on the silk-screen

printed side (parts side) of the PWB diagrams, the parts that are

printed over with black such as the resistor ( ), diode ( )

and ICP ( ) or identified by the " " mark nearby are critical

for safety. When replacing them, be sure to use the parts of the

same type and rating as specified by the manufacturer.

probe on

each exposed

metal part.

1.5 Preventing static electricity

Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser

diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.

1.5.1 Grounding to prevent damage by static electricity

Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products.

Be careful to use proper grounding in the area where repairs are being performed.

(1) Ground the workbench

Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the

traverse unit (optical pickup) on it.

(2) Ground yourself

Use an anti-static wrist strap to release any static electricity built up in your body.

(3) Handling the optical pickup

• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical

pickup are shorted. After replacement, return the shorted parts to their original condition.

(Refer to the text.)

• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily

destroy the laser diode.

1.6 Handling the traverse unit (optical pickup)

(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.

(2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the

replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a

time when attaching it to the connector.

(3) Handle the flexible cable carefully as it may break when subjected to strong force.

(4) I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.

1.7 Attention when traverse unit is decomposed

*Please refer to "Disassembly method" in the text for the pickup unit.

• Apply solder to the short land sections before the card wire is disconnected from the connecto on the servo board. (If the card wire

is disconnected without applying solder, the pickup may be destroyed by static electricity.)

• In the assembly, be sure to remove solder from the short land sections after connecting the card wire.

1.8 Important for laser products

1.CLASS 1 LASER PRODUCT

2.CAUTION :

(For U.S.A.) Visible and/or invisible class II laser radiation

when open. Do not stare into beam.

(Others) Visible and/or invisible class 1M laser radiation

when open. Do not view directly with optical instruments.

3.CAUTION : Visible and/or invisible laser radiation when

open and inter lock failed or defeated. Avoid direct

exposure to beam.

4.CAUTION : This laser product uses visible and/or invisible
