SAFETY STATEMENTS
Federal Communications Commission Statement
This device complies with FCC Rules Part 15. Operation is subject to the following
two conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that
may cause undesired operation.
This equipment has been tested and found to comply with the limits for a class B
digital device, pursuant to Part 15 of the Federal Communications Commission
(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 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 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:
• 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 technician for help.
WARNING! The use of a shielded-type power cord is required in order to
meet FCC emission limits and to prevent interference to the nearby radio
and television reception. It is essential that only the supplied power cord
be used. Use only shielded cables to connect I/O devices to this equipment.
You are cautioned that changes or modications not expressly approved by
the party responsible for compliance could void your authority to operate
the equipment.
