Electromagnetic Compatibility Information

Product Emission Class

Emission Class Levels

Various national agencies (in the United States, the Federal Communications Commission (FCC)) govern the levels of electromagnetic emissions from digital devices. Electromagnetic emissions can interfere with radio and television transmission. To reduce the risk of harmful interference these agencies have established requirements for manufacturers of digital devices.

The manufacturer of a digital device must test and label a product to inform an end-user of the maximum emission level from the product when used in accordance with its instructions. The emissions levels encountered are classified as Class A or Class B. A system that meets the Class A requirements can be marketed for use in an industrial or commercial area. A system that meets the more stringent Class B requirement can be marketed for use in a residential area in addition to an industrial or a commercial area.

The end user is generally held responsible for ensuring that the system is suitable for its environment as stated in the above paragraph, and bears the financial responsibility for correcting any harmful interference.

Modifications

Modifications or changes made to this device, and not approved by Sonus Networks, may void the authority granted by the FCC, or other such agency, to operate this equipment.

Federal Communications Commission Notice

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 create 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 can cause harmful interference in which case the user will be required to correct the interference at the user's expense.

Canadian Notice

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 Industry Canada.

Avis Canadien

Cet appareil numérique n'émet pas de bruits radioélectriques depassant les limites applicables aux appareils numériques de la Classe A prescrites dans le Règlement sur le brouillage radioélectrique édicté par le ministère des Communications du Canada.
