FCC STATEMENT Radiation Exposure Statement NOTE: 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 instruc- tions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equip ment does cause harmful interference to radio or television reception, which can b e 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: 1. 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, includinginterference that may cause undesired operation.2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an ou tlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body
