Erklæring fra Federal Communication Commission (FCC, USA)

Dette udstyr er blevet testet og fundet i overensstemmelse med grænserne for en klasse B digital enhed i henhold til del 15 af FCC-reglerne. Disse grænser er designet til at give rimelig beskyttelse mod skadelig interferens i en boliginstallation. Dette udstyr genererer, bruger og kan udstråle radiofrekvensenergi og kan, hvis det ikke installeres og bruges i overensstemmelse med instruktionerne, forårsage skadelig interferens i radiokommunikation. Der er dog ingen garanti for, at der ikke vil forekomme interferens i en bestemt installation. Hvis dette udstyr forårsager skadelig interferens på radio- eller tv-modtagelse, hvilket kan afgøres ved at slukke og tænde for udstyret, opfordres brugeren til at forsøge at korrigere interferensen ved en af ​​følgende foranstaltninger:

• Drej eller flyt modtagerantennen.
• Øg afstanden mellem udstyret og modtageren.
• Tilslut udstyret til en stikkontakt på et andet kredsløb end det, som modtageren er tilsluttet.
• Kontakt forhandleren eller en erfaren radio/tv-tekniker for at få hjælp.

Denne enhed overholder del 15 af FCC-reglerne. Betjening er underlagt følgende to betingelser: (1) Denne enhed må ikke forårsage skadelig interferens, og (2) denne enhed skal acceptere enhver modtaget interferens, inklusive interferens, der kan forårsage uønsket drift.

FCC advarsel:
Enhver ændring eller modifikation, der ikke udtrykkeligt er godkendt af den part, der er ansvarlig for overholdelse, kan annullere brugerens ret til at betjene dette udstyr.

VIGTIGE BEMÆRKNINGER

Advarsel om samlokalisering:
