Warnings and Servicing Hints

SHOCK, FIRE HAZARD SERVICE TEST:

CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance between

either primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the

face 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 AC

power 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.

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 a 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 a ce que les composants ainsi que les

outils que l'on utilise soient également a ce

potentiel.

WARNUNG

Alle IC und viele andere Halbleiter sind

empfindlich gegen elektrostatische

Entladungen (ESD).

Unsorgfältige Behandlung bei der Reparatur

kann die Lebensdauer drastisch vermindern.

Sorgen sie dafür, das Sie im Reparaturfall

über ein Pulsarmband mit Widerstand mit

dem Massepotential des Gerätes verbunden

sind.

Halten Sie Bauteile und Hilfsmittel ebenfalls

auf diesem Potential.

WAARSCHUWING

Alle IC's en vele andere halfgeleiders zijn

gevoelig voor elektrostatische 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.

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.

WARNING

Safety regulations require that the set be restored to its original condition

and that parts which are identical with those specified be used.

Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke

toestand wordt terug gebracht en dat onderdelen, identiek aan de

gespecifieerde 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 l'apparecchio venga rimesso nelle

condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli

specificati.

Les normes de sécurité exigent que l'appareil soit remis a l'état d'origine et

que soient utilisées les pièces de rechange identiques à celles spécifiées.

"Pour votre sécurité, ces documents

doivent être utilisés par des

spécialistes agrées, seuls habilités à

réparer votre appareil en panne."
