FCC STATEMENT
FEDERAL COMMUNICATIONS COMMISSION &
CANADIAN DEPARTMENT OF COMMUNICATIONS
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used
properly, that is, in strict accordance with the communication. It has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in
Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection against such
interference when the equipment is operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
Black Box LH1500 Media Converters Installation and User Guide (08/05)
This digital apparatus does not exceed the Class A limits for radio noise emission from digital
apparatus set out in the Radio Interference Regulation of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de classe A prescrites dans le Règlement sur le brouillage
radioélectrique publé par le ministère des Communications du Canada.
