FCC Compliance This equipment has been tested and found to comply with the limits for a Class 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 the radio communications. However, there are no guarantees that interference will not occur in a particular installation. Troubleshooting If this equipment does cause harmful interference to radio reception, which can be determined by turning the equipment off and on, the user is encouraged to correct the interference by one or more of the following instructions. Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Consult dealer or an experienced radio technician. Conditions Operation is subject to the following conditions This device may not cause harmful interference. This device must accept any interference received, including interference that may cause undesired operation. FCC Caution This device complies with Part 15 of the FCC rules.
