Radio and Television Interference

This equipment has been tested and found to comply with CISPR

EN55022 Class A, and EN50082-1 (CE) requirements and also 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

Note: This product was verified to meet FCC requirements under

test conditions that included use of shielded cables and connectors

between system components. It is important that you use shielded

cables and connectors to reduce the possibility of causing

interference to radio, television, and other electronic devices.

Canadian Department of Communications Statement

This digital apparatus does not exceed the Class A limits for radio

noise emissions from digital apparatus set out in 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
