Operation is subject to the following two conditions : (1) This Device may not cause harmful interface, and (2) This device must accept any interference received, including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for CLASS B digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment 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 correct the interference by one or more of the following measures: 1.1. Reorient or relocate the receiving antenna. 1.2. Increase the separation between the equipment and receiver. 1.3. Connect the equipment into an outlet on a circuit different from that to which receiver is connected. 1.4. Consult the dealer or experienced radio/TV technician for help. WARNING Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. “CAUTION : Exposure to Radio Frequency Radiation. Antenna shall be mounted in such a manner to minimize the potential for human contact during normal operation. The antenna should not be contacted during operation to avoid the possibility of exceeding the FCC radio frequency exposure limit.
