Federal Communications Commission (FCC) compliance
information statement
This product has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation
The FCC Class B limits are designed to provide reasonable protection against harmful interference when the
equipment is operated 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 your point of purchase or service representative for additional suggestions.
The manufacturer is not responsible for radio or television interference caused by using other than recommended
cables or by unauthorized changes or modifications to this equipment. Unauthorized changes or modifications could
void the user's authority to operate this equipment.
Note: To assure compliance with FCC regulations on electromagnetic interference for a Class B computing device,
use a properly shielded and grounded cable such as Lexmark part number 1021294 for USB attach. Use of a
substitute cable not properly shielded and grounded may result in a violation of FCC regulations.
