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 his own expense. Restrictions apply

to the use of the local-connection port on this series of controllers; failure to observe

these restrictions may result in harmful interference. Always disconnect this port as

soon as possible after completing the setup operation. Any changes or modifications

made to this equipment may void the user's authority to operate the equipment.

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 welchen Fällen der Benutzer

für entsprechende Gegenmaßnahmen verantwortlich ist.

Avertissement!

Cet appareil est un appareil de Classe A. Dans un environnement résidentiel cet

appareil peut provoquer des brouillages radioélectriques. Dans ce cas, il peut être

demandé à l’ utilisateur de prendre les mesures appropriées.
