HANDLING CHIP COMPONENTS

GB WARNING
All ICs and many other semi-conductors aresusceptible to electrostatic discharges (ESD).Careless handling during repair can reduce lifedrastically.When repairing, make sure that you areconnected with the same potential as the massof the set via a wrist wrap with resistance.Keep components and tools also at thispotential.
F ATTENTION
Tous les IC et beaucoup d’autressemi-conducteurs sont sensibles auxdécharges statiques (ESD).Leur longévité pourrait être considérablementécourtée par le fait qu’aucune précaution n’estprise à leur manipulation.Lors de réparations, s’assurer de bien être reliéau même potentiel que la masse de l’appareil etenfiler le bracelet serti d’une résistance desécurité.Veiller à ce que les composants ainsi que lesoutils que l’on utilise soient également à cepotentiel.
ESD
D WARNUNG
Alle ICs und viele andere Halbleiter sindempfindlich gegenüber elektrostatischenEntladungen (ESD).Unsorgfältige Behandlung im Reparaturfall kandie Lebensdauer drastisch reduzieren.Veranlassen Sie, dass Sie im Reparaturfall überein Pulsarmband mit Widerstand verbundensind mit dem gleichen Potential wie die Massedes Gerätes.Bauteile und Hilfsmittel auch auf dieses gleichePotential halten.
NL WAARSCHUWING
Alle IC’s en vele andere halfgeleiders zijngevoelig voor electrostatische ontladingen(ESD).Onzorgvuldig behandelen tijdens reparatie kande levensduur drastisch doen verminderen.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.
I AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sonosensibili alle scariche statiche (ESD).La loro longevità potrebbe essere fortementeridatta in caso di non osservazione della piùgrande cauzione alla loro manipolazione.Durante le riparazioni occorre quindi esserecollegato allo stesso potenziale che quello dellamassa dell’apparecchio tramite un braccialettoa resistenza.Assicurarsi che i componenti e anche gli utensilicon quali si lavora siano anche a questopotenziale.
“Pour votre sécurité, ces documentsdoivent être utilisés par des spécia-listes agréés, seuls habilités à réparervotre appareil en panne”.
GBSafety regulations require that the set be restored to its originalcondition and that parts which are identical with those specified,be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie inzijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,identiek aan de gespecificeerde, worden toegepast.
F
Les normes de sécurité exigent que l’appareil soit remis à l’étatd’origine et que soient utiliséés les piéces de rechange identiquesà celles spécifiées.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zubeachten. Der Original zustand des Geräts darf nicht verändert werden;für Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l’apparecchio 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."

GB Warning !Invisible laser radiation when open.Avoid direct exposure to beam.
S Varning !
Osynlig laserstrålning när apparaten är öppnad och spärrenär urkopplad. Betrakta ej strålen.
SF Varoitus !
Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiinanäkymättömälle laserisäteilylle. Älä katso säteeseen!
DK Advarse !
Usynlig laserstråling ved åbning når sikkerhedsafbrydere erude af funktion. Undgå udsaettelse for stråling.
