This equipment has been tested and found to comply with the limits for a class A digital device, pursuant
to part 15 of the FCC rules.  These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.  This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.  Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at the user’s own expense.

Canadian Regulations

This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on
the radio interference regulations of the Canadian Department of Communications.

Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables

aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.

European Regulations

Warning
This is a Class A product. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate measures.
Achtung !
Dieses ist ein Gerät der Funkstörgrenzwertklasse A. In Wohnbereichen können bei Betrieb dieses Gerätes
Rundfunkstörungen auftreten, in weichen Fällen der Benutzer für entsprechende Gegenmaßnahmen
werantwortlich ist.
Attention !
Ceci est un produit de Classe A. Dans un environment domestique, ce produit risque de créer des
interférences radioélectriques, il appartiendra alors à l’utilsateur de prende les measures spécifiques
