2.0 SAFTETY INSTRUCTIONS
GB
WARNING
All ICs and many other semi-conductors 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 wrist wrap with resistance.
Keep components and tools also at this
potential.
F
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler 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.
ESD
D
WARNUNG
Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.
NL
WAARSCHUWING
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
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.
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 riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.
“Pour votre sécurité, ces documents
doivent être utilisés par des spécia-
listesagréés,seulshabilitésàréparer
votre appareil en panne”.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn 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’état
d’origine et que soient utiliséés les piéces de rechange identiques
à celles spécifiées.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten. 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 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."

Warning !
Invisible laser radiation when open.
Avoid direct exposure to beam.
SVarning !
Osynlig laserstrålning när apparaten är öppnad och spärren
är urkopplad. Betrakta ej strålen.
SF Varoitus !
Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina
näkymättömälle laserisäteilylle. Älä katso säteeseen!
DK Advarse !
Usynlig laserstråling ved åbning når sikkerhedsafbrydere er
ude af funktion. Undgå udsaettelse for stråling.
Caution: These servicing instructions are for use by qualified service personnel only.
To reduce the risk of electric shock do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.
