    SAFETY INFORMATION
        This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.
A       Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safety repair
        complex products such as those covered by this manual.
        Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty.
        If you are not qualified to perform the repair of this product properly and safety, you should not risk trying to do so
        and refer the repair to a qualified service technician.

        Where in a manufacturer's service documentation, for example in circuit diagrams or lists
        of components, a symbol is used to indicate that a specific component shall be replaced only
        by the component specified in that documentation for safety reasons, the following symbol shall
        be used:


B
        - Safety Precautions for those who Service this Unit.
          When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable
          results.
        Caution:
          1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept.
          2. During repair or tests, do not view laser beam for 10 seconds or longer.

           CAUTION: USE OF CONTROLS OR
           ADJUSTMENTS OR PERFORMANCE OF
           PROCEDURES OTHER THAN THOSE
           SPECIFIED HEREIN MAY RESULT IN
           HAZARDOUS RADIATION EXPOSURE.
C
           CAUTION: THE USE OF OPTICAL
           INSTRUMENTS WITH THIS PRODUCT
           WILL INCREASE EYE HAZARD.

            This product is a class 1 laser product, but
            this product contains a laser diode higher
            than Class 1. To ensure continued safety,
            do not remove any covers or attempt to
            gain access to the inside of the product.




D

           Laser diode characteristics
           Wave length:
                DVD: 650 nm to 662 nm
                CD: 775 nm to 795 nm
           Focus lens on Maximum output:
                CD: 2.18 mW
                DVD: 1.33 mW

                      Additional Laser Caution
           Transistors Q17 and Q19 in PCB drive the laser diodes for DVD and CD
E
           respectively. When Q17 and Q19 is shorted between their terminals,
           the laser diodes for DVD or CD will radiate beam. If the top cover is removed
           with no disc loaded while such short-circuit is continued, the naked eyes may
           be exposed to the laser beam.



                                                                  CAUTION
          Danger of explosion if battery is incorrectly replaced.
          Replaced only with the same or equivalent type recommended by the manufacturer.
          Discord used batteries according to the manufacture's instructions.
