TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
q Meter impedance should be equivalent to 1500 ohm shunted
by 0.15µF.
q Leakage current must not exceed 0.5mA. q Be sure to test for leakage with the AC plug in both polarites.
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 REASON 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.
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
30cm away from the laser pick-up unit at all times. Do not stare the laser beam at any time.
2) Do not attempt readjustment, disassemble or repair of the laser pick-up, unless notes 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) When the Top Cover is removed, and POWER SW is turned to the "ON" position, the laser component
will emit a beam for several seconds to detect if a disc is present. During this time (5-10sec.) the laser
may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to
any laser emissions.
2) The laser power level can be adjusted with VR on pick-up PWB, however, this level has been set by
the factory prior to shipping from the factory. Do not adjust this laser level control unless instruction
is provided elsewhere in this manual.
Adjustment of this control can increase the laser emission level from the device.

CLASS 1 LASER PRODUCT
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 are 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 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, aluminum 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 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).
IMPORTANT SAFETY NOTICE
There are special components used in this equipment which are important 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.

2. Storing and Handling Test Discs
Surface precision is vital for DVD test discs. Be sure to store and handle them carefully.
1. Do not place discs directly onto the workbench, etc., after use.
2. Handle discs carefully in order to maintain their flatness.
Place them into their case after use and store them verically. Store discs in a cool place where they are not exposed to direct
sunlight or air from air conditioners.
3. Accurate adjustment will not be possible if the disc is warped from being placed on a surface made of glass, etc. If this
happens, use a new test disc to make optical adjustments.
4. If adjustment is done using a warped disc, the adjustment will be incorrect and some discs will not be playable.
