FJK_RF_7121_A Wireless Digital Transceiver RFB02 FCC NOTE: 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. The antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operated in conjunction with any other antenna or transmitter. The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user's authority to operate the equipment. Note: This equipment contains module , FCC ID LE2RFB02, which qualifies as an UNLICENSED MODULAR TRANSMITTER per FCC Public Notice DA 00-1407. It has been tested and found to comply with Part 15.247 of the FCC Rules. This module has been designed for use by the JSW Pacific Corp. Required labeling. Any device incorporating this module must include an external, visible, permanent marking or label which states: ”Contains FCC ID: LE2RFB02.” Failure to comply with this requirement will void the user’s authority to operate any device that incorporates this module. This equipment complies with FCC radiation exposure limits set forth for uncontrolled equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has very low levels of RF energy that it is deemed to comply without testing of specific absorption ratio(SAR).
