1 Safety Precautions
1.1.      General Guidelines
 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or
    damaged by the short circuit.
 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly
    installed.
 3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

1.1.1.      Leakage Current Cold Check
 1. Unplug the AC cord and connect a jumper between the two
    prongs on the plug.
 2. Measure the resistance value, with an ohmmeter, between
    the jumpered AC plug and each exposed metallic cabinet
    part on the equipment such as screwheads, connectors,
    control shafts, etc. When the exposed metallic part has a
    return path to the chassis, the reading should be between
    1M9 and 5.2M9.
     When the exposed metal does not have a return path to
    the chassis, the reading must be      .




                            Figure 1

1.1.2.      Leakage Current Hot Check (See
            Figure 1.)
 1. Plug the AC cord directly into the AC outlet. Do not use an
    isolation transformer for this check.
 2. Connect a 1.5k9, 10 watts resistor, in parallel with a 0.15
