FCC/IC STATEMENTS

FEDERAL COMMUNICATIONS COMMISSION

AND

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 manufacturer’s

instructions, may cause interference to radio 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 B 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.

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 la classe A prescrites dans le Règlement sur le

brouillage radioélectrique publié par le ministère des Communications du Canada.

EN 55022 Warning: This is a Class A product. In a domestic environment, this

product might cause radio interference, in which case the user might be required

to take adequate measures.
