Warnings and Laser safety instructionsSHOCK, FIRE HAZARD SERVICE TEST:CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance betweeneither primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and theface or Front Panel of product and controls and chassis bottom,Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before ACpower is applied, and verified before return to user/customer.Ref.UL Standard NO.1492.NOTE ON SAFETY:Symbol : Fire or electrical shock hazard. Only original parts should be used to replace any part with symbol Any other component substitution(other than original type), may increase risk or fire or electrical shock hazard.FATTENTIONTous les IC et beaucoup dautres semi-conducteurs sont sensibles aux déchargesstatiques (ESD).Leur longévité pourrait être considérablementécourtée par le fait quaucune précautionnest prise a leur manipulation.Lors de réparations, sassurer de bien êtrerelié au même potentiel que la masse delappareil et enfiler le bracelet serti dunerésistance de sécurité.Veiller a ce que les composants ainsi que lesoutils que lon utilise soient également a cepotentiel.DWARNUNGAlle IC und viele andere Halbleiter sindempfindlich gegen elektrostatischeEntladungen (ESD).Unsorgfältige Behandlung bei der Reparaturkann die Lebensdauer drastisch vermindern.Sorgen sie dafür, das Sie im Reparaturfallüber ein Pulsarmband mit Widerstand mitdem Massepotential des Gerätes verbundensind.Halten Sie Bauteile und Hilfsmittel ebenfallsauf diesem Potential.WAARSCHUWINGAlle ICs en vele andere halfgeleiders zijngevoelig voor elektrostatische ontladingen(ESD).Onzorgvuldig behandelen tijdens reparatiekan de levensduur drastisch doenverminderen.Zorg ervoor dat u tijdens reparatie via eenpolsband met weerstand verbonden bent methetzelfde potentiaal als de massa van hetapparaat.Houd componenten en hulpmiddelen ook opditzelfde potentiaal.AVVERTIMENTOTutti IC e parecchi semi-conduttori sonosensibili alle scariche statiche (ESD).La loro longevita potrebbe essere fortementeridatta in caso di non osservazione della piugrande cauzione alla loro manipolazione.Durante le riparazioni occorre quindi esserecollegato allo stesso potenziale che quellodella massa dellapparecchio tramite unbraccialetto a resistenza.Assicurarsi che i componenti e anche gliutensili con quali si lavora siano anche aquesto potenziale.All ICs and many other semi-conductors aresusceptible to electrostatic discharges (ESD).Careless handling during repair can reducelife drastically.When repairing, make sure that you areconnected with the same potential as themass of the set via a wrist wrap withresistance.Keep components and tools also at thispotential.WARNINGSafety regulations require that the set be restored to its original conditionand that parts which are identical with those specified be used.Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijketoestand wordt terug gebracht en dat onderdelen, identiek aan degespecifieerde worden toegepast.Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.Der Originalzustand des Gerats darf nicht verandert werden.Fur Reparaturen sind Original-Ersatzteile zu verwenden.Le norme di sicurezza esigono che lapparecchio venga rimesso nellecondizioni originali e che siano utilizzati pezzi di ricambiago idetici a quellispecificati.Les normes de sécurité exigent que lappareil soit remis a létat dorigine etque soient utilisées les pièces de rechange identiques à celles spécifiées.“Pour votre sécurité, ces documentsdoivent être utilisés par desspécialistes agrées, seuls habilités àréparer votre appareil en panne.”GBNLIDIFGBNLCL 96532065_002.eps120799G77G77G77G2EG72G74G76G2DG68G6FG72G76G61G74G2DG64G6AG2EG68G72Warnings and Laser safety instructionsGB 4 DVD612 /XX12.LASER SAFETYThis unit employs a laser.
