1-1. Safety Precautions for Repairs
1. Safety Precautions
1) Since the equipment uses laser diode, ensure that eyes and parts of the body do not come near the laser diode while performing repair service.
2) Do not disassemble pickup to repair. If the laser diode is faulty, then replace the complete pickup assembly.
3) Perform repair services away from electrical equipments such as TV to avoid interference from these equipments.
4) Ensure to unplug the power cord from the unit before replacing any parts.
5) Ensure to insert the disc properly into the unit before use.
6) Since this equipment cannot be used as a standalone unit, it must be installed in a PC (586 or higher) with appropriate device driver from the floppy disk to verify proper operation.
7) This equipment has many parts with properties related to safety. These parts are specifically noted in the parts list and schematic drawings. Ensure to replace these parts with new parts that have the same specifications.
- Since the laser diode in the optical pickup bundle can be easily damaged by the static electricity in human body or clothing, use the following grounding guidelines when handling the bundle.
Wear a wrist strap with one end properly grounded. The wrist strap discharges the static electricity in human body.
Work on a conductive material such as copper plate that is properly grounded.
Since the static electricity stored in clothing is not easily discharged, ensure that clothing does not make a contact with the pickup bundle.
1-2. Safety Precautions for Installations
A certain semiconductor components are highly susceptible to damages caused by electrostatic discharge (ESD). Semiconductors components such integrated circuits, field effect transistors, and other semiconductor devices are examples of devices that are highly sensitive to ESD. Use the following guidelines to reduce the damages caused by the ESD.
1) Before handling any semiconductor components or parts that contains semiconductors, immediately discharge all static electricity in the body by making a contact with a grounded metallic object. A commercially available wrist strap may also be used. The static electricity must be discharged to avoid potential impact on the voltage during testing.
2) After removing ESD-sensitive components or parts, place the items on a conductive surface such as on a piece of aluminium to prevent accumulation of charges and exposure to ESD.
3) Use properly grounded soldering iron to solder or to de-solder ESD-sensitive components.
4) Only use anti-static soldering iron to de-solder ESD-sensitive components. Use of soldering irons not classified as “anti -static” has enough electrostatic charges to cause damages to the components.
5) Do not use chemical sprays such as Freon. These chemicals have enough electrostatic charges to cause damages to the ESD-sensitive components.
6) Do not remove replacement parts from the anti-static packaging until they are ready for installation. [Most of the replacement parts are packaged in conductive foam, aluminium, or other conductive materials with all the leads shorted together.]
7) Before removing the anti-static packing materials for the new parts, make a contact with the chassis or protective material for the circuits to discharge the static charges.
8) Minimize body movement when handling unprotected ESD-sensitive parts and components. (The movement of body causes build up of electrostatic charges from friction between layers of clothing, and between the shoes and the carpet which may cause damage to the components.)
Caution: Ensure that the power does not get transferred to
the chassis or to the circuitry, and that all general safety guidelines are followed.

1-3. Static Electricity, PL, and Voltage Safety Precautions
1) Read all safety and operational manuals before operating the product.
2) Keep the safety and operational manuals for future reference.
3) Follow all precautions and operational instructions shown inside or on the outside of the product.
4) Follow all operational and maintenance precautions.
5) Unplug the power cord from the socket before cleaning operation. Do not use liquid or aerosol type of cleaners to clean the exterior cabinet. Use a dry cloth only to clean the dust off the cabinet.
6) Do not use any attachments not recommended by the manufacturer. This may be unsafe and may damage the product.
7) Do not use the product near water such as bathtubs, washbasins, washing machines, swimming pools, or lakes.
8) Never place the product on the bed, sofa, radiator, or near any heat source.
9) Power: Only use the type described on the label.
Contact the dealer if the power type cannot be identified. To operate the product using batteries or other sources of power, consult the operating manual.
10)Lightening: Unplug the power during lightening
and during a long period when the product is not being used.
11) Electrical Overload: Do not plug excessive number of power cords into the outlet or extension outlet to prevent fire hazard and electrical shock.
12) Never put any object or liquid in the product.
It may cause fire or electrical shock due to a potential contact with the power supply and/or short-circuit.
13) Replacement Parts: The service technician
must use a replacement part with the same exact specification. Use of replacement part with incorrect specification may result in fire, electrical shock, and other safety hazards.
14) Safety Inspection: Always perform a safety
inspection after a service and/or repairs.
Important Safety Precaution: The product contains special components important for safety. These components are identified with in the schematic drawings. These components must be replaced with components with the exact same specification to prevent electrical shock, fire, and other hazards. Do not modify any part of the original product design without manufacturer
s permission.
Warning: A death or a serious injury may result if the
instructions are not followed properly.
Caution: Property damage may result if the instructions
are not followed properly.
