WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic
(where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency
(and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.

Among some types of lead free solder currently available,
it is recommended to use one of the following types for the
repair work.
· Sn + Ag + Cu (tin + silver + copper)
· Sn + Cu (tin + copper)
· Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
1. As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.
2. If lead solder must be used, be sure to remove lead free
solder from each terminal section of the parts to be
replaced and from the area around it completely before
soldering, or make sure that the lead free solder and
lead solder melt together fully.

WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may
cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during
servicing of the unit.
1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.
2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.
3) CAUTION: Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
Laser Emitting conditions:
1. This device is a Class IIIb laser device.
Class IIIb means
With the protective case removed, exposure to the light output from the laser, either directly or reflected by a mirror, can
cause harm to the eyes, but there is no danger to the eyes from exposure to dispersed reflected laser light. (Generally 0.5
W or less)
2. Always wear eyeglasses designed for protection against laser light.
3. Always wear gloves.
4. Have no reflective objects anywhere near this device.
5. Figure A shows from where in this device the laser is emitted.
6. When switching on the power to the device for the first time, always measure the laser power with a laser power meter
and check that the power is no greater than the number of Watts in the specifications.
7. Never look directly at the laser light while the laser is emitting light.
8. Do not allow the laser light to shine directly on your skin while the laser is emitting light.
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

I PREVENTION OF ELECTROSTATIC DISCHARGE
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 should 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 such as aluminum 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 an 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, aluminum foil or comparable
conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES device, 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 harmless 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).
Grounding for electrostatic breakdown prevention
1. Human body grounding:
Use an anti static wrist strap to discharge the static electricity
Anti-static wrist strap
from your body.
2. Work table grounding: 1M
Put a grounded conductive material (sheet) or iron sheet on
the area where the optical pickup is placed.
Caution:
The static electricity of your clothes will not be grounded
through the wrist strap. So take care not to let your clothes Conductive material
(sheet) or steel sheet
touch the optical pickup.
