DVD Portable Player PET320/00/05/37 3141 785 30840 Version 1.0 TABLE OF CONTENTS Chapter Technical Specification. 1 Safety Instructions. 2 Instruction for Use 3 Mechanical Instructions. 4 Troubleshooting fr Reparaturen sind Original-Ersatzteile zu verwenden. I Le norme di sicurezza esigono che lapparecchio venga rimesso nelle condizioni originali e che siano utilizzati i pezzi di ricambio identici a quelli specificati. After servicing and before returning set to customer perform a leakage current measurement test from all exposed metal parts to earth ground to assure no shock hazard exist. The leakage current must not exceed 0.5mA. CLASS 1 LASER PRODUCT 3122 110 03420 GBWarning ! Invisible laser radiation when open. Avoid direct exposure to beam. SVarning !

Use an AC voltmeter, having 5000 per volt or more sensitivity. Connect a 1500 10W resistor,paralleled by a 0.15uF 150V AC capacitor between a knomn 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.). SAFTY PRECAUTIONS LEAKAGE CURRENT CHECK Measure the AC voltage across the 1500 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 0.3V.A reading exceeding 0.3V 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 OUTLET AC VOLTMETER Test all exposed metal. Voltmeter Hook-up for Leakage Current Check 0.15uF 150V AC 1500 10W (5000 per volt or more sensitivity) Good earth ground such as a water pipe, conduit, etc. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated dangerous voltage within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 3.
