ESD

© WARNING

All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD). Careless handling during

repair can reduce life drastically.

When repairing, make sure that you are connected with the

same potential as the mass of the set via a wristband with

resistance. Keep components and tools at this potential.

WAARSCHUWING

Alle IC´s en vele andere halfgeleiders zijn gevoelig voor

electrostatische ontladingen (ESD).

Onzorgvuldig behandelen tijdens reparatie kan de levensduur

drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie

via een polsband met weerstand verbonden bent met hetzelfde

potentiaal als de massa van het apparaat.

Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

f ATTENTION

Tous les IC et beaucoup d´autres semi-conducteurs sont

sensibles aux décharges statiques (ESD). Leur longévite

pourrait être considérablement écourtée par le fait qu´aucune

précaution nést prise à leur manipulation.

Lors de réparations, s´assurer de bien être relié au même

potentiel que la masse de l´appareil et enfileer le bracelet

serti d´une résistance de sécurité.

Veiller à ce que les composants ainsi que les outils que l´on

utilise soient également à ce potentiel.

i AVVERTIMENTO

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche

statiche (ESD).

La loro longevità potrebbe essere fortemente ridatta in caso di

non osservazione della più grande cauzione alla loro

manipolazione. Durante le riparationi occorre quindi essere

collegato allo stesso potenziale che quello della massa

delápparecchio tramite un braccialetto a resistenza.

Assicurarsi che i componenti e anche gli utensili con quali si

lavora siano anche a questo potenziale.

d WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich

gegenüber elektrostatischen Entladungen (ESD).

Unsorgfältige Behandlung im Reparaturfall kann die

Lebensdauer drastisch reduzieren.

Sorgen Sie dafür, daß sie im Reparaturfall über ein Puls-

armband mit Widerstand mit dem Massepotential des

Gerätes verbunden sind.

Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem

Potential.

SAFETY

Safety regulations require that the set be restored to its

original condition and that parts which are identical with

those specified be used.

Safety components are marked by the symbol

Veiligheidsbepalingen vereisen, dat het apparaat in zijn

oorspronkeliijke toestand wordt teruggebracht en dat

onderdelen, identiek aan de gespecificeerde, worden toegepast.

De Veiligheidsonderdelen zijn aangeduid met het symbool

Le norme di sicurezza estigono che l´apparecchio venga

rimesso nelle condizioni originali e che siano utilizzati i

pezzi di ricambiago identici a quelli specificati.

© DANGER : Invisible laser radiation when open.

AVOID DIRECT EXPOSURE TO BEAM.

s Varning !

Osynlig laserstrålning när apparaten är öppnad och

spärren är urkopplad. Betrakta ej strålen.

¶ Advarsel !

Usynlig laserstråling ved åbning når sikkerhedsafbrydere

er ude af funktion. Undgå udsaettelse for stråling.

§ Varoitus !

Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina

näkymättömälle laserisäteilylle. Älä katso säteeseen !

©

After servicing and before returning the set to customer

perform a leakage current measurement test from all

exposed metal parts to earth ground, to assure no

shock hazard exists.

The leakage current must not exceed 0.5mA.
