Size This equipment has been tested an d found to comply with the lim its for a Class B digital device, pursuant to Part 15 of the FCC Rules. T hese limits are designed to provide reasonable p rotection against harmful inter ference in a residential installation. This equipment generates, uses and ca n radiate radio frequency energy and, if not installed and used in accordance w ith the instructions, may cause harmful interference to radio communica tions. However, there is no guarantee th at interference will not occur in a particular installation. If this equipment does cause harmful i nterference to radio or television reception, w hich can be determined by turni ng the equipment off and on, the user i s 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 o utlet on a circuit different fr om that to which the receiver is connected. ● Consult the dealer or an experi enced radio/TV technician for h elp. 6. FCC STATEMENT 6. FCC STATEMENT FCC Caution: Any changes or modi fications not expressly approve dby the party responsible for compliance could void the user’s authorit y to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation i ssubject to the following two conditions: (1) This device may not cause har mful interference, and (2) this devic e must accept any interference received, including interference that ma y cause undesired operation. This device and its antenna(s) mu st not be co-located or operat ion in conjunction with any other antenna or transmitter. A UWB device operating under the provisions of this section sha ll transmit only when it is sending informat ion to an associated receiver. The UWB intentional radiator shall cease transmission within 10 seconds unless it receives an acknowledgement from the associated receiver that i ts transmission is being received. An acknowledgement of reception must continue to be received by the U WB intentional radiator at leas tevery 10 seconds or the UWB device must cease transmitting. 6. FCC STATEMENT 6. FCC STATEMENT

No Requirements EUT 1 Have its own RF shielding Device is equipped with metal shielding to cover RF section. Refer to external photos. 2 Have buffered modulation/data inputs (if such inputs are provided) All inputs to the modules are buffered th ought logic or microprocessor inputs. 3 Have it own power supply regulation The part number of the power regulator is ( XC6223-3.3V ) 4 Meet the antenna requirements of Section 15.203 The antenna type is PCB antenna. refer to the external photo. 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing Please reference exhibition Test Conf iguration Photo for the stand-alone test configuration 6 Be labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the out side of the device into which the module is installed must also display a label referring to the enclosed module Label is to be placed in front of the EUT(LBM-002), and other label is to be placed in the User’s Guide. Refer to FCC ID label format. 7 The modular transmitter is manufactured so t hat the user cannot influence the operation of the transmitter that will operate outsi de of the scope of the regulations. The EUT is compliant whith all applicable FCC rules. Detail instructions for maintaining compliance are given in the Users Manual. 8 Address compliance with the Commission’s RF exposure limits in Sections 1.1310 and 2.1091. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(b)(4). This device is categorically excluded from routine environmental because it operate at very low power level
