5、 user, perform thefollowing safety checks.1. Inspect all lead dress to make certain that leads are notpinched or that hardware is not lodged between the chassisand other metal parts in the audio product.2. Inspect all protective devices such as insulating materials,cabinet, terminal board, adjustmen

6、t and compartment coversor shields, mechanical insulators etc.3. To be sure that no shock hazard exists, check for leakagecurrent in the following manner.* Plug the AC line cord directly into a 120 volt AC outlet.* Using two clip leads, connect a 1.5k ohm, 10 watt resistorparalleled by a 0.15F capac

7、itor in series with all exposedmetal cabinet parts and a known earth ground, such asconduit or electrical ground connected to earth ground.* Use a VTVM or VOM with 1000 ohm per volt, or higher,sensitivity to measure the AC voltage drop across theresistor (See diagram).* Connect the resistor connecti

8、on to all exposed metal partshaving a return path to the chassis (antenna, metal cabinet,screw heads, knobs and control shafts, escutcheon, etc.)and measure the AC voltage drop across the resistor.All tests must be repeated with the AC line cord plug connectionreversed.Any reading of 0.3 volt RMS (t
