Federal Communication Commission Interference Statement
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 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 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.
This device complies with part 15 of the FCC Rules.
FCC Caution: To assure continued compliance, any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate this equipment. (Example - use
only shielded interface cables when connecting to computer or peripheral devices).
FCC SAR evaluation:
This equipment complies with SAR test exclusion thresholds.
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.
IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no change to the
antenna orthe device is permitted. Any change to the antenna or the device could result in the device
exceeding the RFexposure require-ments and void user’s authority to operatethe device.
