FOR AMERICAN USERS
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 installed
and used in accordance with the instructions, may cause harmful interference to radio and
television reception. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause interference to radio and television
reception, 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:
0 Reorient or relocate the receiving antenna
0 Increase the separation between the equipment and receiver
0 Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
3 Consult the dealer or an experienced radio/TV technician for help
WARNING
The connection of a non-shielded equipment interface cable to this equipment will
invalidate the FCC Certification of this device and may cause interference levels that
exceed the limits established by the FCC for this equipment. It is the responsibility of the
user to obtain and use a shielded equipment interface cable with this device. If this
equipment has more than one interface connector, do not leave cables connected to unused
interfaces.
Changes or modifications not expressly approved by the manufacturer could void the
user’s authority to operate the equipment.
FOR CANADIAN USERS

digital apparatus as set out in the radio interference regulations of the Canadian
Department of Communications.
Le present appareil numerique n’emet pas de bruits radioelectriques depassant les limites
