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. 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. Caution:. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. RF Exposure Warning: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This device is provided with an internal antenna and minimum 20 cm spacing must be maintained between this PC C Card and all person’s body (excluding extremities of hands, wrist and feet) during wireless mode of operation. Further, this transmitter must not be co- located or operated in conjunction with any other antenna or transmitter.
