SAFETY NOTICE SAFETY PRECAUTIONS LEAKAGE CURRENT CHECK Plug the AC line cord directly into a 120V AC outlet (do not use an isolation transformer for this check). Use an AC voltmeter, having 5000 Ω per volt or more sensitivity. Connect a 1500 Ω 10 W resistor, paralleled by a 0.15 µF 150V AC capacitor between a known good earth ground (water pipe, conduit, etc.) and all exposed metal parts of cabinet (antennas, handle bracket, metal cabinet screwheads, metal overlays, control shafts, etc.). Measure the AC voltage across the 1500 Ω resistor. The test must be conducted with the AC switch on and then repeated with the AC switch off. The AC voltage indicated by the meter may not exceed 0.3 V. A reading exceeding 0.3 V indicates that a dangerous potential exists, the fault must be located and corrected. Repeat the above test with the DVD VIDEO PLAYER power plug reversed. NEVER RETURN A DVD VIDEO PLAYER TO THE CUSTOMER WITHOUT TAKING NECESSARY CORRECTIVE ACTION. READING SHOULD NOT EXCEED 0.3V DVD VIDEO PLAYER AC VOLTMETER (5000 W per volt or more sensitivity) Good earth ground such as a water pipe, conduit, etc. 1500 W 10 W 0.15 µF 150V AC AC OUTLET Test all exposed metal.
