This Class B digital apparatus meets all requirements
of the Canadian Interference-Causing Equipment
Regulations.
Cet appareil numérique de la Classe B respecte toutes
les exigences du Règlement sur le matérier brouilleur
du Canada.
NOTE:
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not in-
stalled and used in accordance with the instructions, may
cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television recep-
tion, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and
receiver.
– Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV techni-
cian for help.
NOTE:
Changes or modifications may cause this unit to
fail to comply with part 15 of the FCC Rules and may void
the user
′
s authority to operate the equipment.
NOTE TO CATV SYSTEM INSTALLER:
This reminder is provided to call the CATV (Cable-TV) system installer's attention to Article 820-40 of the NEC, which
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the
grounding system of the building, as close to the point of cable entry as practical.
