Radio Frequency Interference Statement
NOTE: 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 environ-
ment. 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 cause the user will be required to correct the interference at his own
expense.
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 Commu-
nications
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites appli-
cables aux appareils numériques de classe A prèscrite dans le Règlement sur le brouillage
radioélectrique édict par le Ministère des Communications du Canada.
To maintain compliance with FCC radio frequency emission limits the use of quadshield, RG-6/U
type CATV cable is required for connection to the CATV system. Any changes or modifications
may void the user's authority to operate this equipment.
EN 55 022 Statement
This is to certify that Bay Networks CMTS is shielded against the generation of radio interference
in accordance with the application of Council Directive 89/336/EEC, Article 4a. Conformity is
declared by the application of EN 55 022 Class A (CISPR 22).
Voluntary Control Council for Interference (VCCI) Statement
This is a Class A product based on the standard of the Voluntary Control Council for Interference
from Information Technology Equipment (VCCI). If this is used near a radio or television receiver
in a domestic environment, it may cause radio interference. Install and use the equipment accord-
ing to the instruction manual.
Règlement sur le brouillage radioélectrique du ministère des Communications
Cet appareil numérique CMTS respecte les limites de bruits radioélectriques visant les appareils
numériques de Classe A prescrites dans le Règlement sur le brouillage radioélectrique du Min-
istère des Communications du Canada.
