RADIO FREQUENCY INTERFERENCE STATEMENT
Class B Digital Device. This equipment has been tested and found to comply with the
limits for a Class B computing device pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful interference in a
residential installation. However, there is no guarantee that interference will not occur
in a particular 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 communications. If this equipment does
cause harmful interference to radio or telephone reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the
interference by one 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 an experienced radio/TV technician for help.
Caution:
Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
To meet FCC requirements, shielded cables and power cords are required to connect
this device to a personal computer or other Class B certified device.
This digital apparatus does not exceed the Class B limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.
