PREVENTION OF ELECTRO STATIC DISCHARGE (ESD) TO
ELECTROSTATICALLY SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically
Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip”
components. The following techniques be used to help reduce the incidence of component damage caused by electro static discharge
(ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching
a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for
potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface suck as alminum foil, to prevent
electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only a anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate
electrical charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES
devices are packaged with leads electrically shorted together by conductive foam, alminum foil or comparable conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES divice, touch the protective material to the chassis or
circuit assembly into which the device will be installed.
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise hamless motion such as the brushing together of
your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).
IMPORTANT SAFETY NOTICE
There are special components used in this equipment which are imporant for safety.
These parts are marked by in the schematic diagrams, exploded views and replacement parts list. It is
essential that these critical parts should be replaced with manufacturer’s specified parts to prevent shock, fire, or
other hazards. Do not modify the original design without permission of manufacturer.

PRECAUTION OF LASER DIODE
CAUTION:
This unit utilizes a class I laser. Invisible laser radiation is emitted from the optical pickup lens when the
unit is truned on:
1. Do not look directly into the pickup lens.
2. Do not use optical instruments to look at the pickup lens.
3. Do not adjust the preset variable resistor on the optical pickup.
4. Do not disassemble the optical pickup unit.
5. If the optical pickup is replaced, use the manufactures specified replacement pickup only.
6. Use of control or adjustment or performance of procedures other than those specified herin may result in hazardous
radiation exposure.
HANDLING PRECAUTIONS FOR TRAVERSE DECK
The laser diode in the optical pickup may break down due to
potentical diference caused by static electricity of clothes or
human body.
So be careful of electrostatic break down during repair of the
optical pickup.
Handling of optical pickup
1. Do not subject the optical pickup to static electricity
as it is extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode,
an antistatic shorting pin is inserted into the
flexible board (FPC Board).
When removing or connecting the short pin,
finish the job in as short times as possible.
3. Be careful not to apply excessive stress to the
flexible board (FPC Board).
4. Do not turn the variable resistor (Laser power adjustment).

Grounding for electrostatic breakdown prevention
1. Human body grounding.
Use the antistatic wrist strap to discharge the static
electricity from your body.
2. Work table grounding.
Put a conductive material (sheet) or steel on the area
where the optical pickup is placed and ground the sheet.
Caution:
The static electricity of your clothes will not be grounded
through the wrist strap. So take care not to let your clothes
touch the optical pickup.

ASSEMBLING AND DISASSEMBLING THE OPTICAL PICKUP (MECHANICAL P ARTS)
The optical pickup can be damaged by static electricity from your body. Be sure to take static electricity countermeasures when
working around the optical pickup.
1.Handling the Optical Pickup
The optical pickup can be damaged by static electricity from your body. Be sure to take static electricity countermeasures when
working around the optical pickup.
1. The optical pickup is an extremely high-precision mechanism. Do not subject it to strong impact.
2. To preserve the quality of the optical pickup replacement parts during transport and installation, the terminals of the laser
diode are short-circuited. After replacing the parts, use the proper procedure to return the laser diode to its original condition.
(Refer to page 2-11, Assembling the Optical Pickup.)
3. Testers cannot be used to check the laser diode of the optical pickup. The power supply inside the tester can easily damage
the laser diode.
4. Take care when handling the flexible cable because excessive force can cause it to break.
5. You cannot adjust the semifixed resistor for laser power adjustment. Do not turn it.
2.Disassembly Procedure
