WARNING

GB

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.

CLASS 1

LASER PRODUCT

ATTENTION

GB

Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.

AT TENTION

Tous les IC et beaucoup d'autres
semi-conducteurs sont sensibles aux
decharges statiques(ESD).
Leur longevite pourrait etre considerablement
ecourtee par le fait qu'aucune precaution n'est
prise a leur manipulation.
Lors de reparations,s'assurer de bien etre relie
au meme potentiel que la masse de l'appareil et
enfiler le bracelet serti d'une resistance de
securite.
Veiller a ce que les composants ainsi que les
outils que l'on utilise soient egalement ace
potentiel.

WARNING

D

Alle ICs und viele andere Halbleiter sind
empfindich gegenuber elektrostatischen
Entladungen(ESD).
Unsorgfaltige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie,dass Sie im Reparaturfall uber

ein Pulsarmband mit Widerstand verbunden

sind mit dem gleichen Potential wie die Masse
des Gerates.
Bauteile und Hilfsmittel auch auf dieses gleiche

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.

AVVERTIMENTO

Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche(ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
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 securite,ces documents

doivent etre utilises par des specia-
