Der Original zustand des Geräts darf nicht verändert werden;für Reparaturen sind Original-Ersatzteile zu verwenden.ILe norme di sicurezza esigono che lapparecchio venga rimessonelle condizioni originali e che siano utilizzati i pezzi di ricambioidentici a quelli specificati.“After servicing and before returning set to customer perform aleakage current measurement test from all exposed metal parts toearth ground to assure no shock hazard exist. The leakage currentmust not exceed 0.5mA.“CLASS 1LASER PRODUCT3122 110 03420GB Warning !Invisible laser radiation when open.Avoid direct exposure to beam.S Varning !Osynlig laserstrålning när apparaten är öppnad och spärrenär urkopplad.

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.2-3MCD130 PRODUCT SPEC Sheet-190 Page 1 of 10 Rev.1.0 MCD130 DVD Micro Theatre Hardware Requirement Specification Valid for stroke version: Stroke Version Countries / Region MCD130 /12 Europe /05 UK /37 USA its publication conveys no license under any patent or other right, nor does the publisher assume liability, for any consequence of its use; specifications and availability of goods mentioned in it are subject to change without notice; it is not to be reproduced, in whole or in part, without the written consent of the publisher.MCD130 PRODUCT SPEC Sheet-190 Page 2 of 10 Rev.1.0 MCD130 DVD Micro Theatre Technical Specifications (Philips Sheet-190) Contents 1.
