The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section.” The antennas of the FUJI TECOM.INC’s Leak noise logger are permanently attached. The connection to an outside antenna becomes the structure not to come off easily to fix it by a special screw. Conclusion: The FUJI TECOM INC. FCC ID: 2AARD0002 equipment complies with the requirement of §15.203. e-OHTAMA, LTD., Tokyo LaboratoryTest Report Number EOTEL002 2-8-20 Kurigi, Asao-ku Kawasaki-shi, Kanagawa, JapanForm Rev. 1.00 TEL: +81-44-980-2052 Page 4 of 15 2. Equipment Under Test (EUT) 2.1General Descriptions The loggers mounted with sensors are installed on the ancillary equipment of water pipeline such as valves, fire hydrants and air valves, and “minimum sound levels of water leak noise” are collected at a certain interval. The minimum sound levels recorded on the loggers are transmitted to the data collector via radio communication. The collected minimum sound levels are judged normal or abnormal based on the threshold in the management software and the results are displayed on the map. In addition, the respective logger data displayed in the graph can be compared, and ageing variation can be found. Therefore, faulty pipelines can be detected very effectively. 2.2Detailed Descriptions Product NameLogger Model NumberLNL-1L Serial Number13034030 Power SupplyDC 3.6V Dimension 40.0mmΦ × 110.0mm(H) Operating Frequency 429.250～429.475MHz Equipment CategoryPart15:Remote Control / Security Device Transceiver IC:Wireless Video or Data Device (54-806 MHz) Normal PlacementOutdoor equipment Condition of the EUTProd…
