SERVICE PROCEDURE

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

    1. Replacing the fuses                                                      2. Safety-check out
                                                                                (Only U.S.A. model)
                    This symbol located near the fuse indicates that the        After correcting the original service problem perform the
    fuse used is show operating type, For continued protection against          following safety check before releasing the set to the customer
    fire hazard, replace with same type fuse , For fuse rating, refer to        Connect the insulating-resistance tester between the plug of
    the marking adjust to the symbol.                                           power supply cord and terminal GND on the back panel.
                                                                                Specifications: More than 10M ohm at 500V
                  Ce symbole indique que le fusible utilise est e lent.
    Pour une protection permanente, n'utiliser que des fusibles de meme

    WARNING :   TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN
                OR MOISTURE. DANGEROUS HIGH VOLTAGES ARE PRESENT INSIDE THE ENCLOSURE. DO NOT OPEN THE
                CABINET. REFER SERVICING TO QUALIFIED PERSONNEL ONLY.

    CAUTION :   TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
