 Refer to the service manual in the GSPN (see the rear cover) for more information.
                                                                                                               1. Precautions



1. Precautions

1.1. Safety Precautions

1) Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not
   limited to, the following items:
    a) Be sure that no built-in protective devices are defective or have been defeated during servicing
         i) Protective shields are provided to protect both the technician and the customer. Correctly replace all missing
            protective shields, including any removed for servicing convenience.
         ii) When reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all protective
             devices, including, but not limited to, nonmetallic control knobs, insulating fish papers, adjustment and
             compartment covers/shields, and isolation resistor/capacitor networks. Do not operate this instrument or permit
             it to be operated without all protective devices correctly installed and functioning.
    b) Be sure that there are no cabinet openings through which adults or children might be able to insert their fingers and
       contact a hazardous voltage. Such openings include, but are not limited to, excessively wide cabinet ventilation
       slots, and an improperly fitted and/or incorrectly secured cabinet back cover.
    c) Leakage Current Hot Check -- With the instrument completely reassembled, plug the AC line cord directly into a
       230V(220V ~ 240V) AC outlet. (Do not use an isolation transformer during this test.)
        Use a leakage current tester or a metering system that complies with American National Standard Institute (ANSI)
        C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL) 1270 (40.7). With the instrument's
        AC switch first in the ON position and then in the OFF position, measure from a known earth ground (metal
        water pipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle brackets, metal cabinets,
        screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical
        return path to the chassis.
        Any current measured must not exceed 0.5mA.
        Reverse the instrument power cord plug in the outlet and repeat the test. See
        Any measurements not within the limits specified herein indicate a potential shock hazard that must be eliminated
        before returning the instrument to the customer.

    d) Insulation Resistance Test Cold Check -- (1) Unplug the power supply cord and connect a jumper wire between
       the two prongs of the plug. (2) Turn on the power switch of the instrument. (3) Measure the resistance with
       an ohmmeter between the jumpered AC plug and all exposed metallic cabinet parts on the instrument, such as
       screwheads, antenna, control shafts, handle brackets, etc. When an exposed metallic part has a return path to the
       chassis, the reading should be between 1 and 5.2 megohm. When there is no return path to the chassis, the reading
       must be infinite. If the reading is not within the limits specified, there is the possibility of a shock hazard, and the
       instrument must be repaired and rechecked before it is returned to the customer. See
