Use anAC voltmeter, having 5000 per volt or more sensitivity.Connect a 1500 10W resistor,paralleled by a 0.15uF150V AC capacitor between a knomn good earth ground(water pipe, conduit, etc.) and all exposed metal parts ofcabinet (antennas, handle bracket, metal cabinetscrewheads, metal overlays, control shafts, etc.).SAFTY PRECAUTIONSLEAKAGE CURRENT CHECKMeasure the AC voltage across the 1500 resistor.The test must be conducted with the AC switch on andthen repeated with the AC switch off. The AC voltageindicated by the meter may not exceed 0.3V.A readingexceeding 0.3V indicates that a dangerous potentialexists, the fault must be located and corrected.Repeat the above test with the DVD VIDEO PLAYERpower plug reversed.NEVER RETURN A DVD VIDEO PLAYER TO THECUSTOMER WITHOUT TAKING NECESSARYCORRECTIVE ACTION.READING SHOULD NOT EXCEED 0.3VDVD VIDEO PLAYERAC OUTLETAC VOLTMETERTest all exposed metal.Voltmeter Hook-up for Leakage Current Check0.15uF 150V AC150010W(5000 per voltor more sensitivity)Good earth groundsuch as a water pipe,conduit, etc.The lightning flash with arrowhead symbol, within anequilateral triangle, is intended to alert the user to thepresence of uninsulated “dangerous voltage“ within theproduct's enclosure that may be of sufficient magnitude toconstitute a risk of electric shock to persons.The exclamation point within an equilateral triangle isintended to alert the user to the presence of importantoperating and maintenance (servicing) instructions in theliterature accompanying the appliance.CAUTIONUse of controls or adjustments or performance ofprocedures other than herein may result in hazardousradiation exposure or other unsafe operation.- VOL +Volume control.
