SERVICE PROCEDURES 1
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
 This set employs a laser. Therefore, be sure to follow            Laser Diode Properties
 carefully the instructions below when servicing.
                                                                   Material: GaAS/GaAlAs

    2. Replacement of optical pick-up
    The laser diode in the optical pickup block is so sensitive to static
    electricity, surge current and etc. that the components are liable to
    be broken down or its reliability remarkably deteriorated.
    During repair, carefully take the following precautions.
    1. Solder the LD short terminal on mechanism.
    2. Disconnect the flexible flat cable P101.
    3. Replace the optical pickup.
    4. Connect the flexible flat cable P101.
    5. Unsolder the LD short terminal on mechanism.



                                                                                             Pick up short land




 NOTE
  1. Ground for the work-desk.                                                 3. Grounding for the human body.
     Place a conductive sheet such as a sheet of copper                           Be sure to put on a wrist-strap for grounding whose
     (with impedance lower than 10Mohm) on the work-                              other end is grounded.
     desk and place the set on the conductive sheet so that                       Be particularly careful when the workers wear
     the chassis can be grounded.                                                 synthetic fiber clothes, or air is dry.
  2. Grounding for the test equipments and tools.                              4. Select a soldering iron that permits no leakage and
     Test equipments and toolings should be grounded in                           have the tip of the iron well-grounded.
     order that their ground level is the same the ground of                   5. Do not check the laser diode terminals with the
     the power source.                                                            probe of a circuit tester or oscilloscope.
